Gear Introduction
Bevel Gears
Bevel gears are most commonly used to transmit power between shafts that intersect at a 90 degree angle. They are used in applications where a right angle gear drive is required. Bevel gears are generally more costly and are not able to transmit as much torque, per size, as a parallel shaft arrangement.
Worm Gear
Worm gears transmit power through right angles on non-intersecting shafts. Worm gears produce thrust load and are good for high shock load applications but offer very low efficiency in comparison to the other gears. Due to this low efficiency, they are often used in lower horsepower applications.
Helical Gears
Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel. This causes more than 1 tooth to be in contact during operation and helical gears can carry more load than spur gears. Due to the load sharing between teeth, this arrangement also allows helical gears to operate smoother and quieter than spur gears. Helical gears produce a thrust load during operation which needs to be considered when they are used. Most enclosed gear drives use helical gears.
Spur Gears
Spur gears transmit power through shafts that are parallel. The teeth of the spur gears are parallel to the shaft axis. This causes the gears to produce radial reaction loads on the shaft, but not axial loads. Spur gears tend to be noisier than helical gears because they operate with a single line of contact between teeth. While the teeth are rolling through mesh, they roll off of contact with 1 tooth and accelerate to contact with the next tooth. This is different than helical gears, which have more than 1 tooth in contact and transmit torque more smoothly.
Hypoid Gears
Hypoid gears look very much like a spiral bevel gear, but unlike spiral bevel gears, they operate on shafts which do not intersect. In the hypoid arrangement because the pinion is set on a different plane than the gear, the shafts are supported by the bearings on either end of the shaft.
Herringbone Gears
Herringbone gears are very similar to the double helical gear, but they do not have a gap separating the 2 helical faces. Herringbone gears are typically smaller than the comparable double helical and are ideally suited for high shock and vibration applications. Herringbone gearing is not used very often due to their manufacturing difficulties and high cost.

How does a gear pump handle variations in fluid viscosity?
A gear pump is capable of handling variations in fluid viscosity effectively. Here’s a detailed explanation:
1. Positive Displacement Operation:
One of the key features of a gear pump is its positive displacement operation. Regardless of the fluid’s viscosity, the pump delivers a consistent flow rate with each revolution of the gears. The pump traps and displaces a fixed volume of fluid with each rotation, ensuring that the same amount of fluid is moved regardless of changes in viscosity. This positive displacement action allows the gear pump to handle variations in fluid viscosity and maintain accurate and consistent fluid delivery.
2. Viscosity Range:
Gear pumps are designed to handle fluids with a wide range of viscosities. They can effectively handle low-viscosity liquids as well as highly viscous fluids. The pump’s positive displacement mechanism ensures that the fluid is moved at a consistent rate, regardless of its viscosity. This makes gear pumps versatile and suitable for various applications where fluids of different viscosities need to be pumped.
3. Self-Priming Capability:
Gear pumps have a self-priming capability, which means they can draw fluid into the pump without the need for additional priming mechanisms. This self-priming feature allows gear pumps to handle fluids of varying viscosities, including thicker or more viscous fluids that may be difficult to pump with other types of pumps. The gears create a vacuum effect that draws the fluid into the pump, enabling efficient operation even with varying viscosities.
4. Temperature Considerations:
Fluid viscosity can be affected by temperature variations. Gear pumps are designed to handle a wide range of temperatures, allowing them to accommodate changes in fluid viscosity due to temperature fluctuations. It’s important to consider the temperature limits specified by the pump manufacturer to ensure optimal performance and prevent any adverse effects on the pump or the pumped fluid.
5. Material Selection:
The choice of materials used in the construction of gear pumps can also contribute to their ability to handle variations in fluid viscosity. The materials should be selected based on the compatibility with the range of viscosities and potential chemical properties of the fluids being pumped. Proper material selection helps ensure that the pump can effectively handle the fluid without significant variations in flow rate or delivery accuracy.
In summary, gear pumps handle variations in fluid viscosity through their positive displacement operation, designed viscosity range, self-priming capability, consideration of temperature effects, and appropriate material selection. These features make gear pumps versatile and reliable for pumping fluids with different viscosities in various applications.
Can gear pumps be used for both liquid and gas pumping?
Gear pumps are primarily designed for liquid pumping and are not typically used for pumping gases. Here’s a detailed explanation:
1. Liquid Pumping:
Gear pumps are widely used for pumping various types of liquids, including water, oils, fuels, chemicals, and viscous fluids. The positive displacement action of gear pumps allows them to efficiently move liquids by trapping and displacing a fixed volume of fluid with each revolution of the gears. The close tolerances between the gear teeth and the pump housing help minimize leakage and ensure effective liquid transfer.
2. Gas Pumping:
Unlike liquids, gases are highly compressible and have significantly lower densities. The design and operation of gear pumps are not well-suited for pumping gases due to the following reasons:
- Compression: Gear pumps are not designed to compress gases. When a gas is introduced into the pump’s chamber, it will compress as the gears rotate, leading to increased pressure and reduced volume. This can cause excessive strain on the pump and its components, potentially leading to damage or failure.
- Leakage: Gear pumps rely on close tolerances and tight clearances to minimize leakage in liquid applications. However, these tight clearances are not effective for handling gases, which can easily leak through the small gaps between the gear teeth and the pump housing. This leakage can result in poor efficiency and loss of pumping performance.
- Flow Characteristics: Gases have different flow characteristics compared to liquids. Gear pumps are specifically designed to handle the viscosity and flow properties of liquids, including their lubricating properties. Gases lack these characteristics, and the gear pump’s design may not provide the necessary sealing and lubrication required for efficient gas pumping.
3. Alternative Technologies:
For gas pumping applications, other types of pumps are typically used, such as centrifugal pumps, diaphragm pumps, rotary vane pumps, or specialized gas pumps. These pumps are specifically designed to handle the unique properties of gases, including their compressibility and low density. They incorporate features like gas-tight seals, variable displacement mechanisms, and specialized materials to ensure efficient and reliable gas transfer.
In summary, gear pumps are primarily designed for liquid pumping applications. While they excel at efficiently transferring liquids, their design characteristics and limitations make them unsuitable for pumping gases. For gas pumping, it is recommended to use pumps specifically designed for handling gases to ensure optimal performance and reliability.
Can gear pumps be used for both high-pressure and low-pressure applications?
Yes, gear pumps can be used for both high-pressure and low-pressure applications. Here’s a detailed explanation:
1. High-Pressure Applications:
Gear pumps can be designed and configured to handle high-pressure fluid transfer. By adjusting various parameters such as gear size, tooth profile, operating speed, and material selection, gear pumps can generate the necessary pressure to meet the requirements of high-pressure applications. The close tolerance design and efficient sealing mechanisms of gear pumps contribute to their ability to handle high pressures without excessive leakage or loss of performance.
2. Low-Pressure Applications:
Similarly, gear pumps are also suitable for low-pressure applications. The positive displacement operation of gear pumps allows them to deliver a consistent flow rate even at low pressures. Gear pumps can efficiently handle low-viscosity fluids and transfer them with precision, making them suitable for applications that require accurate metering or low-pressure fluid circulation. Additionally, the compact size and simplicity of gear pump design make them convenient for low-pressure systems where space and simplicity are important considerations.
3. Pressure Control:
Gear pumps can incorporate pressure relief valves or bypass mechanisms to regulate and control the pressure within the system. These features allow gear pumps to adapt to varying pressure requirements and protect the pump from excessive pressure build-up. Pressure relief valves can be set to open and divert excess fluid when the system reaches a specified pressure, ensuring safe and reliable operation in both high-pressure and low-pressure scenarios.
4. System Integration:
Gear pumps can be integrated into different hydraulic or fluid systems to accommodate various pressure levels. They can be used as standalone pumps or as part of a larger system, working in conjunction with other components such as valves, filters, and control devices. The flexibility and versatility of gear pumps make them adaptable to a wide range of pressure requirements across different industrial applications.
5. Application Considerations:
When selecting a gear pump for a specific application, it’s essential to consider the desired pressure range, flow rate, viscosity, and other system requirements. Proper sizing, material selection, and configuration of the gear pump will ensure optimal performance and longevity in both high-pressure and low-pressure applications.
In summary, gear pumps can effectively handle both high-pressure and low-pressure fluid transfer applications. Their design versatility, pressure control options, and ability to integrate into various systems make gear pumps a reliable choice for a wide range of pressure requirements in different industries.
