Description
Technical field:
The utility model relates to a kind of secondary gear reducer, belongs to decelerator technical field.
Background technology:
Decelerator plays coupling rotating speed and transmitting torque between prime mover and working machine or executing agency, and decelerator is a kind of relatively accurate machinery, and the object that uses it is to reduce rotating speed, increases torque. Can be divided into single-stage and multi-stage speed reducer according to transmission progression difference; Can be divided into cylinder gear speed reducer, cone gear reducer and circular cone-Cylinder Gear running wheel decelerator according to tooth factory wheel shape; Can be divided into again expansion, shunting and enter together shaft type decelerator according to the arrangement form of transmission. Decelerator is a kind of individual components being made up of the gear drive, worm-drive, the gear-worm-drive that are enclosed in stiff case, is commonly used for the speed reduction gearing between driving link and working machine. Between prime mover and working machine or executing agency, play coupling rotating speed and transmitting torque, in modern mechanical, application is very extensive.
Reductor is generally used for the drive apparatus of low rotation speed large torque, motor, internal combustion engine or other power running up are reached to the object of deceleration by the gear wheel on the few gear engagement output shaft of the number of teeth on the power shaft of reductor, common reductor also has and several same principle gear is reached to desirable deceleration effect, the ratio of the number of teeth of large pinion is exactly gearratio. Reductor is a kind of relatively accurate machinery, and the object that uses it is to reduce rotating speed, increases torque. It of a great variety, model is different, and variety classes has different purposes. Decelerator of a great variety, can be divided into gear reduction unit, worm reducer and planetary reducer according to transmission type; Can be divided into single-stage and multi-stage speed reducer according to transmission progression difference; Can be divided into cylinder gear speed reducer, cone gear reducer and circular cone-cylinder gear speed reducer according to gear shape; Can be divided into again expansion, shunting and coaxial-type decelerator according to the arrangement form of transmission.
Decelerator, in running, generally adopts gear engagement to carry out transmission, and thus, the friction between gear can produce heat, if decelerator heat radiation is insufficient, can cause the interlock of travelling gear, greatly reduces the decelerator life-span.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of secondary gear reducer, and its design science is reasonable, simple in structure, and maintenance and repair is convenient, uses extensively, easy to use.
A kind of secondary gear reducer of the present utility model, it comprises: one-level pinion, reducer input shaft, one-level gear wheel, decelerator base, oil sealing, reducer output shaft, bearing, secondary gear axle, left box body lid, reduction case, described reduction case is fixedly mounted on decelerator base, left box body lid is arranged on reduction case, described reducer input shaft is arranged on left box body and covers, one-level pinion is arranged on reducer input shaft, described secondary gear wheel is arranged in reduction case, reducer output shaft is arranged on secondary gear wheel, between described reducer output shaft and reduction case, install by oil sealing, described secondary gear axle is arranged on the bottom of reduction case by bearing, one-level gear wheel is arranged on secondary gear axle.
Further, described left box body lid and reduction case all adopt cast iron quality to process, and described one-level pinion and one-level gear wheel are meshed transmission gear.
The beneficial effects of the utility model: its design science of the utility model is reasonable, simple in structure, maintenance and repair is convenient, uses extensively, easy to use.
