SEW style's Vertical Upward worm gear factory

worm gear

The feature of the enveloping worm

Because the difference of forming principle, the enveloping worm set compares with normal column worm shaft set. There are many differences in the features of joggle. The following features of surface worm shaft in the joggle are:

1.Many joggling teeth numbers at the same time:

The teeth of surface worm shaft along with the circle of the worm gear to encircle the teeth of worm gear. In theory, all the teeth of the worm shaft can attend to the joggle, and joggle many teeth at the same time, so every tooths bearing load is small, the bearing of the whole worm shaft fit will enhance.

2. The teeth surface of the worm gear shows the crewel contact

In the second envelop process, just because the twice contact principle, the tooth surface of the worm gear can show appear the phenomena of crewel contact, the crewel contact has increased the length of contact line, minished the load of the length of the unit contact line.

3.The angle between the positions of opposite move and the contact line

This angle is called lubricative angle. The bigger the angle the better.

Our Worm Gears:

1. Bespoke manufacture of white drawing or sample will be suppied.

2. Technology support from excellent engineers with more than 10 years Experiences.

3. Durable service life from selected material and precise CNC processing equipment.

4. Low MOQ is acceptable upon the drawing details.

5. High Quality with a Competitive Price

6.100% QC inspection defore delivery.

7. Convinient Transportation. (Ningbo/Shanghai)

Advantage:

1.Enveloping worm sets power is 2 to 3 times of with the same one center distance , under the consituation of transmission the same power,circular reducer gearboxs outline size only is 1/2 to 1/3 of common cyclindrical worm reducer

2.Because enveloping worm set form s consituation is well,so in the process of work, to be liquid lubrication or critical liquid lubrication. There be not directly friction ,between worm gear and worm wheel ,so is small, transmission efficiency is high

3.The main form of invalidity for worm is abrasion, and . These matter all be got conquered successfully, under the same condition, s useful life is 5 to 10 times of common
