Abstract
The present invention discloses a kind of roller cam speed-reducer, and its technological scheme is an affixed anchor ring shape cam on the input shaft of speed reducer, and the star-wheel of affixed and cam-engaged has radial tire on the output shaft on it, on each tire roller is housed.Advantage is the efficient height, little power consumption, and volume is little, and is in light weight, and maintenance is easy and expense is low, simple in structure, and cost of production is low, reaches country and consumes raw material and electric energy less, and society obtains the purpose of the retarder of long service life.
Description
The invention belongs to a kind of retarder.
At present the kind of retarder is a lot, but with regard to structure, traditional mainly with gear as transmission component substantially, using more for a long time is gear and worm transmission structure.Only there is a tooth to do the transmission of power during this class retarder engagement, thereby the load of unit forced element is big, must cause physical dimension to increase, when engagement, have sizable relative sliding velocity simultaneously, so quite a few energy consumption is in the relative friction of engagement, so efficient is low, having is that this class retarder all adopts cast tin bronze again, and its contact allowable stress is no more than 220Mpa, and intensity is relatively poor, the very easy gummed of the flank of tooth and going to pot causes working life low.
The purpose of this invention is to provide a kind of novel roller cam speed-reducer, the efficient height, the life-span is long, and volume is little, and is in light weight, and cost is lower.
The object of the present invention is achieved like this: affixed anchor ring shape cam on the input shaft of speed reducer, the star-wheel of affixed and cam-engaged has radial tire on the output shaft on it, on each tire roller is housed.
Working principle: connect input shaft by motor, the input of moment of torsion and rotating speed is passed to cam, and cam passes to roller with power, and roller can rotation can revolve round the sun again and produce moment and pass to star-wheel, star-wheel passes torque to output shaft, reaches the purpose of moment of torsion and speed change output.
The present invention compared with prior art has following advantage:
1, owing to employing rolling friction on the structure replaces sliding friction, thus the efficient height, mechanical efficiency can be up to 98% in the transmission system, and overall efficiency is more than 90%.
2, lack consuming electric power 10-26% than traditional retarder.
3, volume and weight reduces 5-15% than traditional retarder.
4, maintenance is easy, and maintenance cost is low, and easily damaged parts is a small roller, not only change easily, and it is few to spend.
5, long service life doubled than traditional retarder life-span.
6, simple in structure, technology is easy, and cost of production is lower.
Provide embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is cam of the present invention and roller mesh schematic representation.
Fig. 4 is the star wheel structure schematic representation.
Fig. 5 is the cam tooth schematic representation of opening rectangle.
Fig. 6 is semicircular cam tooth schematic representation.
See Fig. 1-6, embodiments of the invention are as follows: install input shaft 2 on the casing 1, and assembling cam 4 on it, cam 4 is the anchor ring shape, and the protruding 4 teeth groove sectional shapes of taking turns are opening rectangle 7, can also be semicircle 8.Teeth groove is a single-wire helix, can also be two-wire, multi-thread spiral.Assembling output shaft 5 on the casing 1, assembling star-wheel 3 has radial tire 6 on it on the star-wheel 3, and a roller 9 is housed on each tire 6, and roller 9 is rolling bearings, and star-wheel 3 is by roller 9 and cam 4 engagements.
The present invention can be used as deceleration or drives up, and also can make the usefulness of calibration.
