Description
Technical field:
The utility model relates to a kind of speed reducer, especially cam output to-and-fro motion speed reducer.
Background technique:
Some mining machineries or other need mechanically reciprocating, usually need speed reducer as power transmission, existing reduction gearbox output shaft generally rotates along same circumferencial direction, reduction gearbox output shaft can not be realized reciprocal rotation, just need more additional external agencies to realize the to-and-fro motion of executive component so in use, as the lifting means used on the mine, pumping unit etc., external agency's (as crankrocker mechanism) takes up room greatly, transmission efficiency is low, and the power source power that needs is bigger.
The model utility content:
Can not realize the back and forth deficiency of rotation in order to overcome existing reduction gearbox output shaft, the utility model provides a kind of cam output to-and-fro motion speed reducer, the output shaft of this cam output to-and-fro motion speed reducer can be realized crankmotion, output shaft directly links to each other with reciprocating executive component, has the high characteristics of compact structure and transmission efficiency.
The technical solution of the utility model is: this cam output to-and-fro motion speed reducer comprises casing, input shaft and output shaft, commutation input shaft and commutation output shaft are arranged between input shaft and the output shaft, between input shaft and commutation input shaft and output shaft and the commutation output shaft all by gear transmission, be fixed with big small trochal disc respectively on commutation input shaft and the commutation output shaft, be fixed with eccentric big grooved wheel on the big trochal disc, there is small grooved wheel at the small trochal disc center, be wound with wire rope on the big small grooved wheel, one end of wire rope is fixed on the off-centered side of small trochal disc, and the other end is fixed on the casing.
The center fixed of above-mentioned wire rope has support block; Wire rope is a chain: the outward edge of big grooved wheel is inlaid with bearing; Wire rope is fixed by the side of roller and small trochal disc.
The utlity model has following beneficial effect: owing to take such scheme, eccentric big grooved wheel rotates wire rope is tightened, and affects the small trochal disc rotation to the greatest extent, and the commutation output shaft is rotated, and output shaft is just changeing; After eccentric big grooved wheel forwarded certain position to, wire rope loosened, and wire rope is removed the pulling force of small trochal disc, and output shaft reverses under the effect of gravity or other loading force; Wire rope is tightened, so just formed the clockwise and anticlockwise of reduction gearbox output shaft, output shaft can be realized crankmotion, and output shaft directly links to each other with reciprocating executive component, compact structure, transmission efficiency height.
