Abstract
The utility model discloses a three-axle cycloid pin gear reducer, which comprises an output axle, an output axle fastening ring, a gland, a frame, an air permeable cap, double eccentric bearings, a pin axle, a pin sleeve, a needle shell, a separation ring, a needle sleeve, a needle pin, a cycloid pin gear, an end cap, an input axle, an input axle fastening ring, bearings, oil seal, etc., wherein, the part at the left end of the input axle extending out of a case body is a first axle which can connect with other mechanisms; the part extending towards the other end of the input axle and passing through the inner hole of the output axle is a third axle which can connect with other mechanisms. The output axle is made into a hollow axle with a step inner hole, the part extending out of the case body is a second axle which connects with other mechanisms. The three-axle cycloid pin gear reducer can satisfy requirements of special mechanisms such as mechanisms with positive and reverse movements and different speeds, mechanisms needing double-power driving, coaxial double-brake mechanisms, etc. The utility model has the advantages of a double-axle cycloid pin gear reducer, and can be made into horizontal, vertical or motor direct-linked types.
Description
Affiliated technical field
The utility model relates to a kind of cycloidal planetary gear speed reducer, and three cycloid pin speed reducers of three projecting shafts are arranged.
Background technique
At present, known cycloidal planetary gear speed reducer is a kind of application Gear Planet Transmission principle, adopt the cycloid pin to vow the gearing down machinery of engagement, have that velocity ratio is big, efficient is high, volume is little, in light weight, running steadily, characteristics such as noise is low, shock-resistant, overload capacity is strong, the life-span is long.Be widely used in the mechanical transmission in fields such as lifting transportation, metallurgy, mine, petrochemical industry, light industry, chemical industry, food.Because cycloidal planetary gear speed reducer has only cross-compound arrangement so far, can not satisfy the requirement that specific compound action mechanism is arranged, as: forward and reverse motion is arranged, and the different mechanism of forward and reverse movement velocity; Need mechanism with double dynamical driving; Use the mechanism of coaxial pair of brake structure etc.
The model utility content
There is the deficiency that can not satisfy the requirement that specific compound action mechanism is arranged in order to overcome existing cycloidal planetary gear speed reducer, the utility model provides a kind of three cycloidal planetary gear speed reducers, this machine is except that having the original advantage of twin shaft cycloidal planetary gear speed reducer, it has three projecting shafts, can be respectively realize connecting, can satisfy the requirement of specific compound action mechanism with three mechanisms.
In order to solve the problems of the technologies described above, on the basis of the biaxial type structure of cycloidal planetary gear speed reducer, output shaft is made hollow shaft.Simultaneously an end of input shaft prolongs, and passes from the output shaft endoporus and to extend to outside the output shaft.The 3rd axle that formation can connect with other mechanism.
The technological scheme that the utility model technical solution problem is adopted is: three cycloidal planetary gear speed reducers by output shaft, shaft retaining ring, gland, support, ventilative cap, double-eccentric shaft hold, bearing pin, guide, pin vow that shell, spacer ring, pin vow that cover, pin vow pin, cycloidal-pin wheel, end cap, input shaft, go into main zero (portion) part such as a retaining ring, bearing, oil sealing and form.Output shaft is made the hollow shaft of platform valency endoporus, and endoporus is equipped with bearing, oil sealing.Its outer fenestra is made stepped ramp type, and bearing, oil sealing also are housed on the cylindrical step.Input shaft passes the output shaft endoporus and extends to outside the output shaft, the 3rd axle that formation can connect with other mechanism.
The beneficial effects of the utility model are: have rational in infrastructure, compact, volume is little, efficient is high, cost is low.For cycloidal planetary gear speed reducer family increases a new architecture that can satisfy specific compound action mechanism demand, widened the Applicable scope of cycloidal planetary gear speed reducer.
