Zeal Gears Pvt. Ltd. offers the best quality Two Stage Helical Gear Box with Oil Pump that is widely used for power transmission in various industries.
Helical Gear Box Two Stage
We have already discussed the helical gearbox one stage. And from our discussion, we know by now that they are highly efficient gearboxes to work with. Then, why do we need an addition to the family of helical gearboxes? Or, why specifically the requirement of the helical gearboxes two stage?
The answer is quite simple. Their need arises because of the following factors:
- They provide a two stage gear reduction performance between the output and the input shaft.
- And second they are required for power transmission purposes.
So, in industrial applications where heavy-duty work is required it becomes the more appropriate choice. We manufacture and supply a wide range of helical gear two stage with unmatched quality.
Design of helical gearbox two stage
Now, designing one stage helical gearboxes are quite simpler processes. But as we proceed towards multistage gearboxes the design becomes more complex. Their designs are usually very large and are highly constrained.

|---|---|---|---|
| CD-80MM | CD-200MM | Rs 40,000 | Rs 2,40,000 |
What makes it more complex?
Well, the fact that we would be using different subsets and obviously there would be some kind of interaction between those subsets. That makes the whole designing procedure a Whole lot more tedious if you ask me.
Now, the choice of gear width and the centre distance that you keep between the different subsets is going to influence the gear reduction capacity of helical gearboxes greatly.
So, our engineers optimize the dimensions of the subsets of the gearboxes in such as way that it provides you with maximum gear reduction and high power transmission capacity. Thus, making your procedure a whole lot more efficient.
They have a compressive range of constraints groups utilized in the designing process. Till date at least 24 constraints groups have been studied and implicated in the designing of two stage helical gearboxes.
Now, the basic function of these constraints groups is to minimize the overall volume and second to minimize as much power loss as they can.
Basic design
The basic design of the helical gearbox two stage remains the same as the one stage helical gearboxes.
In essence, they are cast in the same grained iron or steel alloys with anticorrosive metals added to it. And their interior is coated with the coat of anticorrosive paint, high-performance oil and heat-resistant materials.
They have proper lubrication are sealed at the junctions to prevent any oil spillage. They are as efficient as helical gearboxes can be with high power transmission capacity, torque and heat transmission capacity.

FAQ for Two-Stage Helical Gearbox
What is a two-stage helical gearbox?
A two-stage helical gearbox is a gear reducer that uses two sets of helical gears to achieve greater speed reduction. It provides a higher reduction ratio than a single-stage gearbox, allowing for more significant speed reduction and torque increase.
What are the advantages of using a two-stage helical gearbox?
- Higher Reduction Ratios: Allows for more significant speed reduction in a compact design.
- Smooth Operation: Helical gears offer quieter and smoother operation compared to other gear types.
- Improved Torque: Provides higher torque output due to the increased gear stages.
- Versatility: Suitable for applications requiring substantial speed reduction and high torque.
How does a two-stage helical gearbox differ from a single-stage helical gearbox?
A two-stage helical gearbox has two sets of helical gears, which allows for greater reduction ratios and higher torque output compared to a single-stage gearbox, which has only one set of gears. The two-stage gearbox can provide more substantial speed reduction while maintaining compactness.
What factors should be considered when selecting a two-stage helical gearbox?
- Reduction Ratio: Ensure the gearbox provides the required speed reduction for your application.
- Load Capacity: Verify that the gearbox can handle the torque and load requirements.
- Efficiency: Check the gearbox’s efficiency to minimize energy loss.
- Size and Mounting: Consider the dimensions and mounting options to fit your installation space.
- Operating Environment: Take into account environmental factors such as temperature, dust, and moisture.
What maintenance is required for a two-stage helical gearbox?
- Routine Inspections: Regularly check for signs of wear, leaks, and unusual noises.
- Lubrication: Maintain proper lubrication levels and use the recommended lubricant.
- Cleaning: Keep the gearbox and surrounding area clean to prevent contamination.
- Alignment Checks: Ensure the gearbox is properly aligned with connected equipment to avoid premature wear.
What are common issues with two-stage helical gearboxes and their solutions?
- Excessive Noise: May indicate misalignment, insufficient lubrication, or gear wear. Check alignment, ensure proper lubrication, and inspect gears.
- Overheating: Often due to inadequate lubrication or excessive load. Verify lubrication levels and check that the gearbox is not overloaded.
- Vibration: Can result from misalignment or imbalance. Ensure proper alignment and secure mounting.
What materials are used in two-stage helical gearboxes?
Two-stage helical gearboxes are commonly made from high-strength steel for the gears and cast iron or aluminum for the housing. The material choice depends on the load requirements and operating conditions.
Can a two-stage helical gearbox be customized?
Yes, manufacturers often offer customization options, including different gear ratios, mounting configurations, and materials to suit specific application needs.
How is a two-stage helical gearbox installed?
- Alignment: Properly align the gearbox with the input and output shafts.
- Mounting: Securely mount the gearbox to prevent movement or vibration.
- Lubrication: Apply the recommended lubricant and ensure proper levels.
- Connection: Ensure the input and output shafts are correctly connected.
Where can I find replacement parts or service for a two-stage helical gearbox?
Contact the gearbox manufacturer or authorized distributors for replacement parts and service. Additionally, specialized repair services are available from third-party providers for maintenance and repairs.
