Background technique
Prior art " a kind of hole-pin translation pinwheel cycloid in planet retarder " patent No. ZL200620162473.2, form by eccentric input shaft, pin, translational disk, pin tooth, hypocycloid gear ring and output shaft, input shaft, pin, translational disk and support are formed hole-pin circle parallel moving mechanism, uniform being fixed on of pin tooth constitutes pinwheel on the translational disk, hypocycloid gear ring and output shaft are fixedly connected, have the pin-and-hole that is uniformly distributed along the circumference on the translational disk, pin is uniformly distributed along the circumference and is fixed on the frame; The flank profil of described pin tooth is round; The flank profil of described hypocycloid gear ring is a hypocycloid curve; Described pinwheel is provided with sleeve.The structure that adopts pinwheel and translational disk to unite two into one is compared with double crank ring-plate-type pin pendulum Gear Planet Transmission, has saved ring flat-plate, and volume simple in structure is little, saves material.Compare with the transmission of hole-pin involute planetary, avoided the interference of tooth profiles problem, manufacturing is easy, and mounting or dismounting are easy, and cost reduces.When hypocycloid gear ring and sprocket wheel or belt wheel connect firmly when making output element together, can be made into deceleration sprocket wheel or speed reducing pulley.When input shaft rotates, drive the translational disk motion, owing to be subjected to the restriction of pin to do the circle translation, pin tooth and epicyclodial wheel engagement drive its dead axle and rotate, and as output movement, are exported away by output shaft, realize surely than transmission.The problem that this retarder exists is that pin and pin tooth are cantilever beam structure, and stressed bad, flexural strength is low, and rotary arm bearing is stressed big, and bearing capacity reduces, and the retarder transmission power reduces.In order to improve pin and pin beam strength of tooth, must increase the diameter of pin and pin tooth, cause the radial dimension of retarder to increase like this, also limit the number of teeth of pin tooth in addition, the number of teeth of pin tooth can not be too many, so be not suitable for making the retarder of large speed ratio.
The model utility content
The purpose of this utility model is that a kind of force-bearing situation that improves pin tooth and rotary arm bearing will be provided, and improves their bearing capacity; Reduce the retarder size, increase the pin pendulum planetary reducer of its speed ratio and transmission power.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hole-pin pin pendulum planetary reducer is characterized in that, mainly is made up of input shaft 1, eccentric shaft 2, rotary arm bearing 3, translational disk 4, protecgulum 5, housing 6, inner ring 7, pin tooth 8, epicyclodial wheel 9 and output shaft 10:
The outer ring of inner ring 7 is circular, and in the housing 6 with the internal diameter round chamber of packing into, the inner ring of inner ring 7 circumferentially evenly distributes corresponding with pin tooth 8 positions, quantity, and diameter is greater than a plurality of semicircle orifices of pin tooth 8 diameters, and the external part of pin tooth 8 inserts in the described semicircle orifice.
The epicycloidal wheel tooth of epicyclodial wheel 9 is meshed with pin tooth 8, and epicyclodial wheel 9 is an one with output shaft 10 fixed connections.
The diameter difference of described pin tooth 8 and inner ring 7 first circular holes equals 2 times of throw of eccentric of eccentric shaft 2 and input shaft 1.
The axis of described input shaft 1, inner ring 7, epicyclodial wheel 9 and output shaft 10 is on same straight line.
Adopt the technical program, inner ring 7 is formed hole-pins circle parallel moving mechanisms, and the diameter difference of pin tooth 8 and inner ring 7 first circular holes equals 2 times of throw of eccentric of eccentric shaft 2 and input shaft 1.Pin tooth 4 is meshing with each other with the gear teeth of epicyclodial wheel 9.The axis of input shaft 1, inner ring 7, epicyclodial wheel 9 and output shaft 10 is on same straight line.Circumferentially the distribution circle of semicircle orifice is identical uniformly on pin tooth 8 and the inner ring 7, the quantity and the position of inner ring 7 first circular holes are corresponding with pin tooth 8, during work, input shaft 1 rotates, driving eccentric shaft 2 rotates, drive translational disk 4, owing to be subjected to the restriction of inner ring 7 first circular holes to translational disk 4 pin teeth 8, translational disk 4 is made the circle translational motion.Pin tooth 8 connects firmly on translational disk 4, also makes the circle translational motion, realizes the round translational motion of pinwheel.Pin tooth 8 and epicyclodial wheel 9 engagements drive epicyclodial wheel 8 dead axles and rotate, and cross the output shaft 10 that connects firmly with it and will rotate output, realize slowing down.When the cycloid wheel active, can realize speedup.
The beneficial effects of the utility model are: the utility model is by introducing inner ring 7, pinwheel and pin are united two into one, 7 pairs of pin teeth 8 of inner ring have supporting effect, improved the force-bearing situation of pin tooth 8 and rotary arm bearing 3, reduce the suffered moment of flexure of pin tooth 8, reduce the stressed of rotary arm bearing, improved the flexural strength of pin tooth 8, thereby improved the bearing capacity of retarder.In addition, saved the column pin hole on the translational disk 4, and can reduce pin tooth 8 diameters, made compact structure, size is little, and cost reduces.
