Two, background technique
At present, our employed retarder major part is a gearing, and its structure is to be provided with the gear teeth on cylindrical circumference, and being meshed by the different numbers of teeth reaches the purpose of deceleration.This retarder reduction speed ratio is more stable, reliable operation, but its volume and weight is big, needs a large amount of steel raw materials, the manufacture cost height, and also work together noise and the vibration of this retarder is very big.Just because of there is above-mentioned defective in the gear type retarder, people invent and develop belt wheel formula retarder, ball type retarder, electromagnetic rail brake and cycloid formula retarder.This retarder is compared with the gear type retarder and has been enlarged gear range, has reduced volume and weight, and noise and vibration alleviate greatly, have reduced the manufacture cost of retarder, have improved working efficiency, have obtained prolongation the working life of retarder.
It is to be processed with cycloid groove on the end face of two disks and with the immediate cycloid formula of the utility model retarder, drive by steel ball between two cycloid groove and mesh, but this cycloid formula retarder in use the axial pretightening device in running because vibration is easy to generate loosening.The heat that circular housing is produced owing to friction when work is not easy to shed, and the stressed side of track is easy to wearing and tearing near the tooth top place during overlond running, and track is easy to generate distortion, thereby the gap between track and the ball is become greatly, produces loosening and noise once more.
Three, model utility content
The purpose of this utility model is exactly in order to solve the problem that existing cycloid formula retarder exists on structural design, in use is easy to generate looseningly, and heat is not easy to shed, thereby a kind of new technological scheme is provided.
For achieving the above object, the utility model can be realized by following scheme:
A kind of novel cycloidal ball retarder, it is made up of input part and output, the input part is that the end at housing is provided with axis hole, the fixed pendulum drum is housed in axis hole, input shaft, steel ball and movable pendulum drum, output is that another corresponding end at housing is provided with axis hole, be provided with the movable pendulum drum in the axis hole, steel ball and output shaft, input shaft rolls mutually with steel ball by the movable pendulum drum with output shaft and is connected, right-hand member at input shaft is provided with eccentric shaft e (e is a throw of eccentric), on eccentric shaft, the movable pendulum drum is housed by bearing, be manufactured with cycloid groove on one end face of movable pendulum drum, also be manufactured with cycloid groove on fixed pendulum drum and the corresponding end face of movable pendulum drum, between the cycloid groove of fixed pendulum drum and movable pendulum drum and cycloid groove, steel ball be housed; Being manufactured with diameter on the other end of movable pendulum drum is the annular nest of 2e, is manufactured with the steel ball nest on output shaft and the corresponding end face of movable pendulum drum, forms the W output mechanism behind the embedding steel ball.
The cycloid groove that is located on movable pendulum drum one end face is an annular with its shape of cycloid groove on the corresponding end face of fixed pendulum drum, is provided with a spill oil storage tank in the cycloid groove bottom, is used for trapped fuel and mate is lubricated.Be axially arranged with Thrust nut at output shaft.
The advantage that the utility model had is: simple in structure, volume is little, and is in light weight, and cost is low, and long service life turns round during work steadily flexibly, and the transmission efficiency height is not easy during use to produce and becomes flexible, and radiating effect is very good.The utility model robot, medical apparatus, servo-system, aerospace vehicle etc. require that volume ratio is less, velocity ratio is bigger and also based on the occasion of transmitting movement in use very extensive.
Four, description of drawings
Accompanying drawing 1 is a kind of example structure schematic representation of the utility model;
Accompanying drawing 2 is movable pendulum drum (5) the structure enlarged diagrams in the utility model accompanying drawing 1;
Accompanying drawing 3 is right TV structure schematic representation of the utility model accompanying drawing 2 movable pendulum drums (5);
Accompanying drawing 4 is left TV structure schematic representation of the utility model accompanying drawing 2 movable pendulum drums (5).
Five, embodiment
Now with specific embodiment the utility model is described in further details in conjunction with the accompanying drawings:
The utility model is to be provided with axis hole at the corresponding two ends of housing, in the axis hole input part is housed; In another axis hole output is housed.The input part is made up of input shaft 1, bearing and movable pendulum drum 5, and input shaft 1 is fixedly connected by bearing and bearing cap 2, and bearing cap 2 plays sealing here and tightens up effect; Output is made up of movable pendulum drum 5, steel ball 4, balancing weight 6, output shaft 14, and output shaft 14 is undertaken fastening by bearing 8,10 and precompressed nut 13, between bearing 10 and precompressed nut 13 seal ring 11 is housed.Bearing 8,10 here play supporting role, and described precompressed nut 13 is provided with Thrust nut 12.Be manufactured with the deceleration part that the steel ball 4 of movable pendulum drum 5, fixed pendulum drum 3 and the some of cycloid groove 15 is formed with fixed pendulum drum 3 corresponding faces, present embodiment is provided with 12 steel ball nests 17 and is made up of 12 steel balls.Movable pendulum drum 5 one sides are provided with closed annular cycloid groove 15, are manufactured with annular steel ball nest 17 on the same radius of another side, and its size is decided by the radius of steel ball.When input shaft 1 rotated, the eccentric shaft on it drove by rotary arm bearing and makes 5 revolution of movable pendulum drum.The internal and external cycloids groove of scribing on two cycloid disc end faces is formed the cyclic track of a sealing, steel ball 4 in the cyclic track is made pure rolling, and movable pendulum drum 5 is being fixed on housing 7, force movable pendulum drum 5 the revolution in again around self axis rotation, thereby the formation planetary motion has realized retarded motion.It is that the steel of 2e (e is a throw of eccentric) is asked nest 17 that the other end of movable pendulum drum 5 is manufactured with diameter, and the opposing end surface of output shaft 14 is carved with the steel ball nest of 12 quantity, forms the W output mechanism after embedding steel ball.Circular groove and steel ball nest guarantee the correctness of transmission of movement according to the parallel-crank mechanism principle design.Under the motion of steel ball 4, with the transmission of movement of movable pendulum drum 5 to output shaft 14, thereby realize slowly running of output shaft 14.Be provided with bolt 9 in housing 7 lower ends and play the emptying effect here.Be axially arranged with Thrust nut 12 at output shaft 14, Thrust nut 12 has been played and tight effect with former precompressed nut 13, solved the axial play problem that retarder produces owing to vibration in movement process, vibration reduces, friction also reduces, and the heat that is produced by vibration also just reduces naturally.Increase the oil storage tank 16 that a ring cross-section is shaped as spill in the bottom of cycloid groove 15, be used to store oil plant, mate has been lubricated, reduced the retarder heating.Experimental results show that: under the load test state, compared with prior art oily temperature drop is low 10 ℃, and noise has reduced 5dB.
