Abstract
The utility model relates to an outer-board electric rotary drum, composed of a left supporting seat, a left end cover, a rotary drum, a left supporting shaft, an output left end cover, a right end cover, a right supporting shaft, a right supporting seat, a motor, an input shaft, and a speed reducer. The motor is arranged on the outer part of the rotary drum, the motor is connected with the right supporting seat tightly, a motor shaft is directly connected with the input shaft through a flat key, the input shaft and an output shaft are in the same shaft line, the speed reducer adopts a planet cyclo gear speed reducer, and the planet cyclo gear speed reducer is arranged in the rotary drum. The utility model has the advantages of simple structure, convenient maintenance, stable operation, large bearing capacity, good heat dispersion, and long service life of motors.
Description
The utility model relates to various belt conveyers, bucket elevator, the driving device that winch is supporting.
At present, common supporting motorized pulleys of belt conveyer, bucket elevator, winch on the market, its speed reduction gearing mostly is involute cylindrical gear gearing speed-reducer, worm type of reduction gearing or epicyclic reduction gear, because double reduction transmission device inside and outside adopt more, so part is more, complex structure, efficient is lower, and volume is big.The double reduction gear that the disclosed utility model patent 87215919 of Chinese patent communique has adopted cycloidal-pin wheel retarder and epicyclic reduction gear to be combined into, the structure that makes motorized pulleys is compact, volume is less, bearing capacity has had raising, but because this cylinder adopts the motor built in type, and adopted two reduction gear, thus still existed motor radiating relatively poor, complex structure, maintenance is inconvenient, the defective that range of use is restricted.
The purpose of this utility model is the weak point in the above-mentioned technology, provides a kind of simple in structure, and motor radiating is good, running steadily, the fitted outside motorized pulleys that bearing capacity is big.
The utility model is realized in the following way:
Be the fitted outside motorized pulleys, comprise left support abutment, left end cap, barrel, left bolster, output left end cap, right end cap, right bolster, right support abutment, motor, input shaft and retarder, it is characterized in that: motor places the barrel outside, and connect fastening with right support abutment, motor shaft is by flat key and input shaft direct connection, make input shaft and output shaft on same axis, retarder adopts planetary cycloidal pin gear reducer, and planetary cycloidal pin gear reducer is installed in the barrel.
It is that the circumference tooth curve is the Cycloidal Wheel of curtate epicycloid profile of tooth that above-mentioned planetary cycloidal pin gear reducer adopts, and Cycloidal Wheel is meshed with the pin tooth that is fixed on pin wheel housing, and pin wheel housing is connected with bolt with right end cap.
The right part of above-mentioned input shaft is provided with holdback.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1, generalized section of the present utility model.
Fig. 2, holdback generalized section.
Among the figure: cover, 20 free-wheel clutchs, 21 braking overcoats in 1 left support abutment, 2 left end caps, 3 barrels, 4 left bolsters, 5 output left end caps, 6 pin wheel housings, 7 gear pins, 8 pin gear sleeves, 9 right end caps, 10 Cycloidal Wheel, 11 right bolsters, 12 right support abutments, 13 motors, 14 holdbacks, 15 input shafts, 16 eccentric bushings, 17 bearing pins, 18 guidees, 19 brakings.
As shown in the figure, motor 13 is connected fastening with right support abutment 12, motor shaft and input shaft 15 flat key direct connection, input shaft 15 is supported by the two bearings in right support abutment 12 and right bolster 11 holes, in hollow right bolster 11, pass, the power of motor 13 is input in the cylindrical shell 3, and input shaft 15 connects with eccentric bushing 16 with flat key again, rotates thereby drive eccentric bushing 16.On eccentric bushing 16, be with bearing, bearing outside diameter is installed in Cycloidal Wheel 10 holes, bearing pin 17 passes in the pin-and-hole of Cycloidal Wheel 10 distributions by guide 18, guide 18 connects fastening with output left end cap 5 and right bolster 11, rotation with input shaft 15 is slided, the curtate epicycloid profile of tooth that the circumference tooth curve of Cycloidal Wheel 10 adopts, be meshed with the pin tooth on being fixed on pin wheel housing 6, the pin tooth is to be made of pin gear sleeve 8 and gear pin 7, promote the slide relative that pin gear sleeve 8 and gear pin 7 contact as face with the rotation of Cycloidal Wheel 10, thereby promote the pin tooth, because of the external cycloidal teeth-shaped radius of curvature is big, so there is the tooth of nearly half meshing and bearing load.6 of pin wheel housings are fixing by bolt and right end cap 9, drive barrel 3 rotations with the rotation of Cycloidal Wheel 10.
The utility model has following advantage:
1, simple in structure, be convenient to maintenance.
2, smooth running, bearing capacity is big.
3, perfect heat-dissipating prolongs motor service life.
Claims (3)
1, a kind of fitted outside motorized pulleys, comprise left support abutment, left end cap, barrel, left bolster, output left end cap, right end cap, right bolster, right support abutment, motor, input shaft and retarder, it is characterized in that: motor places the barrel outside, and connect fastening with right support abutment, motor shaft is by flat key and input shaft direct connection, make input shaft and output shaft on same axis, retarder adopts planetary cycloidal pin gear reducer, and planetary cycloidal pin gear reducer is installed in the barrel.
2, fitted outside motorized pulleys according to claim 1, what it is characterized in that the planetary cycloidal pin gear reducer employing is that the circumference tooth curve is the Cycloidal Wheel of curtate epicycloid profile of tooth, Cycloidal Wheel is meshed with the pin tooth that is fixed on pin wheel housing, and pin wheel housing is connected with bolt with right end cap.
3, fitted outside motorized pulleys according to claim 1 is characterized in that being provided with holdback in the right part of input shaft.
