Abstract
The slide block type universal coupling with the same angular speed is composed of active axle coupling head, joint bearing, slide block, passive axle coupling disk and radial branch rods. The radial branch rods installed with joint bearing with slide block in correspodent guide slot are symmetrically made on the active axle coupling head, which is coupled with the passive one in surface contact mode with included angle up to 30 deg. Its advantages include simple and novel structure and greater transmission torque.
Description
The present invention relates to a kind of iso-angular velocity universal coupling with slider of making through machining with metallic material that is used for mechanical transmission.
In mechanical transmission, when the axis of driving shaft and driven axle has been asked certain angle, just need the transmission of using Hooks coupling universal coupling to rotate.Present employed coupling kind is a lot, it is commonly used mainly contains cross Hooks coupling universal coupling, three fork arm roller type Hooks coupling universal couplings and Rzeppa type Hooks coupling universal coupling etc., wherein cross Hooks coupling universal coupling is the transmission of non-isogonism speed, then two kinds is the transmission of isogonism speed, because it has the transmission efficiency height, performance is good and be widely used, but because the complex structure of the coupling of these isogonism speed transmissions, the requirement on machining accuracy height, quenching hardness is big, and ubiquity the high shortcoming of cost.And,, the application area of existing coupling is suffered restraints so its bearing capacity is subjected to certain limitation because its reasons in structure causes the transmission way of contact is line contact.End is got up, and existing coupling technology ubiquity complex structure, processing difficulties, and bearing capacity is little, manufactures shortcomings such as cost height.
The objective of the invention is to overcome the shortcoming that exists in the existing angular speed universal coupling technology, seek a kind of novel structure of design and manufacture, process and manufacture iso-angular velocity universal coupling with slider easy, that cost is low, bearing capacity is bigger.
In order to realize the foregoing invention purpose, the present invention mainly contain driving shaft coupling head, joint shaft bearing, slide block, driven axle tie-plate and radially parts such as fork arm constitute.Symmetry was shaped on three radially fork arms around driving shaft connected first end, on each fork arm joint shaft bearing is housed, the slide block of selecting for use antiwear cast iron alloy to make is housed on the joint shaft bearing, driving shaft coupling head the other end center is shaped on cylindrical bore, save material with weight reduction, driving shaft coupling head and driven axle tie-plate contact jaw center are shaped on segment shape plush copper, play the role of positioning, symmetry is shaped on three opening guide-track grooves around on the driven axle tie-plate, and slide block is respectively charged in the corresponding opening guide-track groove.The opening guide-track groove is the linear rail groove with the parallel axes of driven axle tie-plate, play the aligning effect by slide block slippage and joint shaft bearing on driven axle tie-plate opening guide-track groove, make when between driving shaft coupling head and the driven axle tie-plate axis angle being arranged, but guarantee still isogonism speed transmission of the present invention.Owing to adopted area of contact is big when stressed joint shaft bearing and slide block transmitting element, thereby can transmit bigger load as load.
The present invention compared with prior art be the face way of contact owing to structurally become original line contact, and it is big to have carry-over moment, and it is simple that the slide block processing of transmitting element is manufactured, and is convenient to heat treatment, can reduce advantages such as complete machine cost.
Fig. 1 is the present invention's structural principle schematic representation.
Fig. 2 is that the present invention is perpendicular to the axial direction generalized section.
Further specify below in conjunction with accompanying drawing.In the enforcement, complete machine adopts metallic material to manufacture through machining and forms, 120 ° of symmetries of an end circumferentially-spaced of driving shaft coupling head 1 are shaped on three radially fork arms 5, three radially are equipped with standard piece joint shaft bearing 2 respectively on the fork arm, suit slide block 3 on each joint shaft bearing outer shroud, slide block 3 are packed in the corresponding opening guide-track groove 6 on the driven axle tie-plate 4.Radially fork arm 5, segment shape plush copper 8 and driving shaft coupling head 1 as a whole parts.The center is shaped on cylindrical bore 7 in the driving shaft coupling head, not influence the complete machine performance be principle to alleviate complete machine weight, the other end of driven axle tie-plate 4 is shaped on driven axle 9, and a passive tie-plate 4 is the face way of contact with driving shaft coupling head 1, thereby has big carry-over moment.
In the course of the work, driving shaft coupling head 1 is by radially fork arm 5 power transmissions are to joint shaft bearing 2, and driven axle tie-plate 4 is given in 3 power transmissions of process slide block again, orders about its isogonism speed and rotates.When between driving shaft coupling head 1 and driven axle tie-plate 4 axis angle being arranged, slide block 3 slippage in opening guide-track groove 6, the swing of the land portions of joint shaft bearing 2, three radially fork arm 5 in joint shaft bearing, do small slip.Angle between the axis of driving shaft coupling head 1 of the present invention and driven axle tie-plate 4 can reach 30 °.
