Abstract
The utility model discloses the speed reducer that a kind of novel volume is little and transmission efficiency is high, comprise casing, input shaft and output shaft, input shaft is located on casing by bearing housing, a thrust-bearing is separately installed with inside the radial bearing of input shaft and output shaft one end, stretch into casing internal input shaft and be provided with worm gear, worm gear and the runner be positioned on casing internal output shaft are connected by meshing transmission, and input shaft and output shaft are hollow shaft, and the inwall of described hollow shaft is provided with spline.The beneficial effects of the utility model: compared with prior art, the utility model is by being separately installed with a thrust-bearing inside the radial bearing of input shaft and output shaft one end, the frictional force of radial bearing back-up ring can be reduced, ensure the lithe of running, decrease kinetic equation loss, also reduce noise, and input shaft is connected by bearing, make product performance more stable and reliable.
Description
Technical field
The utility model relates to speed reducer technical field, particularly relates to the speed reducer that a kind of novel volume is little and transmission efficiency is high.
Background technique
Speed reducer is widely used speed change gear in the middle of mechanical transmission, be generally used for the transmission device of low rotation speed large torque, motor, internal-combustion engine or other power run up are reached the object of deceleration to gearwheel on output shaft by the few meshed transmission gear of the number of teeth on the input shaft of speed reducer, but various speed reducer output torque power is little in the market, usage mode is more single, thus can be restricted, its internal structure also more complicated, substantially increase installation and fabricating cost.
Model utility content
For deficiency of the prior art, the utility model provides the speed reducer that a kind of novel volume is little and transmission efficiency is high.
To achieve these goals, technical solution adopted in the utility model is:
The speed reducer that a kind of novel volume is little and transmission efficiency is high, comprise casing, input shaft and output shaft, input shaft is located on casing by bearing housing, described bearing is ball bearing, be separately installed with a thrust-bearing inside the radial bearing of input shaft and output shaft one end, stretch into casing internal input shaft and be provided with worm gear, worm gear and the runner be positioned on casing internal output shaft are connected by meshing transmission, input shaft and output shaft are hollow shaft, and the inwall of described hollow shaft is provided with spline.
Tooth on described worm gear becomes middle part cambered surface recessed, is bolted to connection on input shaft.
The beneficial effects of the utility model: compared with prior art, the utility model is by being separately installed with a thrust-bearing inside the radial bearing of input shaft and output shaft one end, the frictional force of radial bearing back-up ring can be reduced, ensure the lithe of running, decrease kinetic equation loss, also reduce noise, and input shaft is connected by bearing, make product performance more stable and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the speed reducer that a kind of novel volume is little and transmission efficiency is high, comprise casing 1, input shaft 2 and output shaft 3, input shaft 2 is located on casing 1 by bearing housing, described bearing is ball bearing, a thrust-bearing 4 is separately installed with inside input shaft 2 and the radial bearing of output shaft 3 one end, stretch into the inner input shaft 2 of casing 1 and be provided with worm gear 5, worm gear 5 and the runner 6 be positioned on casing 1 inner output shaft 3 are connected by meshing transmission, input shaft 2 and output shaft 3 are hollow shaft, the inwall of described hollow shaft is provided with spline, tooth on described worm gear 5 becomes middle part cambered surface recessed, be bolted to connection on input shaft 2.
The beneficial effects of the utility model: compared with prior art, the utility model is by being separately installed with a thrust-bearing inside the radial bearing of input shaft and output shaft one end, the frictional force of radial bearing back-up ring can be reduced, ensure the lithe of running, decrease kinetic equation loss, also reduce noise, and input shaft is connected by bearing, make product performance more stable and reliable.
