產品特色
A spur gear has a cylindrical pitch surface with teeth that are parallel to the axis. Spur Gears are widely used in kinds of application. We can do the shaping, hobbing and grinding, the max size we can do is 6000mm.
Unlike spur gears, which feature teeth that are parallel to the axis of the gear, helical gears have teeth that are cut at an angle. During the engagement of the teeth, contact begins at one end of the tooth, and then spreads gradually throughout rotation, until full mesh is achieved. The teeth of the helical gears then gradually exit mesh in the same manner.
A worm gear is used when a large speed reduction ratio is required between crossed axis shafts which do not intersect. A basic helical gear can be used but the power which can be transmitted is low. A worm drive consists of a large diameter worm wheel with a worm screw meshing with teeth on the periphery of the worm wheel. The worm is similar to a screw and the worm wheel is similar to a section of a nut. As the worm is rotated the wormwheel is caused to rotate due to the screw like action of the worm. The size of the worm gearset is generally based on the centre distance between the worm and the wormwheel.
RTR max size for worm gears is 2000mm.
