Description

Technical Field

[0001] The utility model relates to the field of copper worm gears, in particular to a copper worm gear which can prevent from falling off. Background Art

[0002] Copper worm gear usually refers to the copper parts used in worm gear superchargers, such as copper bearing sleeves. In worm gear superchargers, the role of copper worm gear is to form a double oil film between the shaft and the bearing seat, which can reduce friction and protect the bearing. When working, the copper worm gear will rotate with the shaft in the middle of the bearing seat, so it needs to have good wear resistance and corrosion resistance. The material of copper worm gear is usually chromium-copper alloy, and the surface will be plated with a layer of lead-tin alloy or metal indium to improve its performance.

[0003] The copper worm gear in the prior art is generally directly nested on the rotating shaft and then subjected to some simple reinforcement treatment. Such an assembly method may cause the worm gear to fall off the rotating shaft due to insufficient reinforcement, thereby causing some safety accidents.

[0004] Therefore, a copper worm gear that can prevent falling off is introduced. By setting a screw between the limit hole and the screw hole, the device can limit and fix the entire worm gear through the limit plate to prevent the worm gear from falling off during operation, avoiding the problem of the worm gear falling off the rotating shaft due to insufficient reinforcement, which in turn causes some safety accidents.

By setting a nesting column welded to the front end of the rear limit block, when the device is assembled with the gear shaft, the rear will naturally limit the gear shaft, thereby improving the stability and applicability of the device. By setting a nesting mouth 1 to match the outer size of the nesting column, the installation between the gear shaft and the nesting column is made more firm and simple, thereby improving the stability and convenience of the device.
