How do you design a gearbox?
The first step in the gearbox design process is to select the material. A material is to be selected by doing intensive research on the properties of the various materials. A material is to be selected keeping in mind the various parameters like strength, weight, durability, cost and other parameters.
What is a gearbox engineering?
The gearbox is a mechanical method of transferring energy from one device to another and is used to increase torque while reducing speed.
What is single stage gearbox?
In most single-stage gearboxes, the output shaft rotates in a direction opposite the input shaft. But with each additional stage, the direction of rotation is reversed again. So in the two-stage gear arrangement shown here, the output rotates in the same direction as the input.
What are the consideration while designing gearbox?
With this information, gearbox manufacturers can better assist you in selecting the correct gearbox for your intended application.
- Your choice: standard, modified standard, or complete custom.
- Main specs.
- Operation (duty cycle)
- Temperature range.
- Grease/oil.
- Environment.
- Input needs.
- Output needs.
How many types of gearboxes are there?
In general, there are three different types of gearboxes: concentric, parallel, and right angle.
What is a 3 stage gearbox?
A three-stage gearbox is obtained by means of increasing the length of the ring gear and adding another planet stage. A transmission ratio of 100:1 is obtained using individual ratios of 5:1, 5:1 and 4:1.
What are the requirement for design of a gear drive?
For the technical requirements, the design inputs include: Overall gear ratio and number of different reductions and their gear ratios if multi-speed and the ratio tolerance. Size and envelope requirements. Weight restrictions.
How do you calculate gearbox size?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
