Description
Technical field
The present invention relates to a kind of mining winch speed reducer, be particularly useful for mining double speed and use winch more, also be applicable to the winch of other type.
Background technology
Disclosed No. 200610038523.0 patents have been authorized by Patent Office of State Intellectual Property Office, this patent disclosure a kind of mining winch speed reducer technical scheme, this scheme adopts conventional mechanical retarder and two-stage brake equipment, but actv. is realized double speed operation and braking, the raising that all improves to some extent of aspects such as life-span, tractive force, work efficiency, but still exist assembling difficulty, the inconvenient and certain potential safety hazard of speed governing.As: bearing assembling, dismounting in the inner blind hole of brake bracket are very difficult, are difficult to location and lubricated; The speed governing of employing shifting slide gear must be stopped earlier before the speed governing, comes speed governing by motor crawl or the moving retarder of manual dish again, is difficult to speed governing fast and accurately when using at the scene, makes troubles to operation; Connect between internally toothed annulus and the coaxial dual gear and brake bracket connects with another dual gear all by the articulation bolt group, loose or dislocation easily such as bolt, nut brings certain potential safety hazard in long-term work.
