Abstract
The utility model relates to a speed reducer with a hardened tooth surface. The speed reducer comprises an input gear shaft, a primary driven gear, an intermediate gear shaft, a secondary driven gear, an output shaft, an engine seat and a box cover. The teeth of the input gear shaft and the intermediate gear shaft are inclined teeth, and the primary driven gear and the secondary driven gear are bevel gears. The input gear shaft is fixed on the engine seat through a cone bearing, a bearing cover, an oil seal and a bearing end cover, the intermediate gear shaft is fixed on the engine seat through the cone bearing and the bearing cover, and the output shaft is fixed on the engine seat through a bearing, a bearing block, the bearing cover, a circular nut (including a backing ring) and the oil seal. The speed reducer with the hardened tooth surface, disclosed by the utility model, has the advantages of small volume, light weight, strong bearing capability, two purposes of standing and lying, high connection precision, stable transmission and low noise.
Description
Technical field
The utility model relates to a kind of speed reducer, particularly relates to a kind of hard-tooth surface speed reducer.
Background technique
Hard-tooth surface speed reducer is widely used in fields such as metallurgy, mine, lifting, transportation, cement, building, chemical industry, weaving, printing and dyeing, pharmacy.Hard-tooth surface speed reducer is that a kind of power is passed on mechanism, and it utilizes the velocity transducer of gear, the winding number of motor is decelerated to desired winding number, and obtain the device of big torque.Hard-tooth surface speed reducer is a kind of accurate relatively machinery, and the purpose of using it is to reduce rotating speed, increases torque.But traditional hard-tooth surface speed reducer volume is bigger, and bearing capacity is not strong, and transmission is not steady, and noise is bigger.
The model utility content
The technical problem that the utility model solved is to provide a kind of hard-tooth surface speed reducer, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of hard-tooth surface speed reducer; Comprise input gear shaft, one-level driven gear, intermediate gear shaft, secondary driven gear, output shaft, support, case lid; The tooth of said input gear shaft and intermediate gear shaft is helical teeth, and one-level driven gear and secondary driven gear are helical gear.Said input gear shaft is fixed on the support through cone bearing, bearing cap, oil sealing and bearing (ball) cover; Said intermediate gear shaft is fixed on the support through cone bearing and bearing cap, and said output shaft is fixed on the support through bearing, bearing support, bearing cap, round nut (containing gasket ring) and oil sealing.Said one-level driven gear is fixed on the intermediate gear shaft through key and axle sleeve, and the secondary driven gear is fixed on the output shaft through key and axle sleeve.Said input gear shaft and the engagement of one-level driven gear, intermediate gear shaft and the engagement of secondary driven gear.
Beneficial effect: the utility model volume is little, and is in light weight, and bearing capacity is strong, and it is dual-purpose to stand, crouch, and it is high to connect precision, stable drive, and noise is low.
