Description
Technical field
The utility model relates to a kind of high-power spiral bevel gear speed reducer.
Background technique
Speed reducer plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and speed reducer is a kind of relatively accurate machinery, uses its object to be reduce rotating speed, increases torque.The individual components that it is a kind of gear transmission by being enclosed in stiff case, worm drive, pinion-endless screw transmission form, be commonly used for the speed reduction gearing between driving link and working machine, between prime mover and working machine or actuator, play coupling rotating speed and transmitting torque, apply very extensive in modern mechanical.
Traditional hard tooth surface speed reducer for spiral bevel, the input flange generally including casing and be fixedly connected with casing, input flange place is provided with input shaft, the corresponding casing one end of input shaft is provided with input gear, but its driving mechanism complex structure, difficulty of processing is larger, there is overall volume large, transmitting torque is little, noise is large, overload capacity is little, the shortcomings such as working life is short, in use easily produce slippage, larger impact is existed on the intensity of axle, reduce safety coefficient, when power is larger, axial force is larger, the speed reducer life-span is caused greatly to be reduced, and when using in larger dust atmosphere, speed reducer is poor in sealability, dust easily enters wherein, speed reducer is caused normally to use.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, there is provided a kind of structure simple, novel, overall volume is little, transmitting torque is large, noise is little, overload capacity is large, longer service life, sealing and the good high-power spiral bevel gear speed reducer of anti-dust performance.
The utility model solves the technological scheme that its technical problem adopts: a kind of high-power spiral bevel gear speed reducer, there is body and curved-tooth bevel gear wheel shaft, output shaft and the first gear shaft and the second gear shaft is provided with in described body, one end of output shaft is provided with only lid, its the other end is provided with logical lid, the two ends of the first gear shaft and the second gear shaft are mounted with end cap by bolt, one end of curved-tooth bevel gear wheel shaft is provided with keyway, its the other end is connected with spiral bevel gear, spiral bevel gear engages with the first gear shaft, first gear shaft is engaged with the second gear shaft by the first gear, second gear shaft is engaged with output shaft by the second gear.
Further, described logical lid and output shaft joint are provided with oil sealing, and the effect of oil sealing is exactly generally isolated with parts of exerting oneself by the parts needing in transmission part to lubricate, and is unlikely to allow oil seepage.
Further, the two ends of described output shaft and the first gear shaft and the second gear shaft are equipped with bearing, and described bearing is four-point contact ball.
Further, be provided with distance ring between the first described gear shaft and spiral bevel gear, between the second gear shaft and the first gear, be provided with distance ring, distance ring is provided with between second gear and output shaft, by dead for bearing nail in bearing support, can well ensure axial position, can not displacement be produced.
Further, described bearing and end cap and be provided with adjustment ring between only covering, adjust axial dimension chain when adjustment ring is for assembling, it is made to meet the axial fiting property of the assembling of design, and not easy oil leakage, be coated with low temp. electric black chromium plating on the surface, not easily get rusty, there is good dust-proof effect.
The beneficial effects of the utility model are: the utility model structure is simpler, novel, overall volume is little, transmitting torque is large, noise is little, overload capacity is large, longer service life, sealing and anti-dust performance good, when power is larger, larger infringement can not be caused, there is locking functions, do not affect the intensity of axle.
