Abstract
The utility model relates to a three-fork sliding equal angular speed universal coupling, which is a universal coupling used for turning transmission when a definite included angle is arranged between axial lines of a drive shaft and a driven shaft, and the utility model is convenient to be processed and reduce the cost. The utility model is characterized in that one end of a coupling head (1) of the drive shaft is three radial direction fork levers (7) which are separated with 120 DEG, the three fork levers are respectively sheathed with joint bearings (2), and the joint bearing can use an existing standard part. Each joint bearing is provided with a plunger piston (3), the plunger pistons are respectively inserted into a sleeve (5), the sleeves are made of babbitt alloy, and the three sleeves (5) are respectively embedded into three uniformly distributed axial cylindrical holes on a coupling flange (4) of the driven shaft.
Description
The utility model relates to the Hooks coupling universal coupling in a kind of mechanical transmission.
In mechanical transmission, when between the axis of driving shaft and driven axle certain angle being arranged, the transmission of then using Hooks coupling universal coupling to rotate.Cross Hooks coupling universal coupling commonly used is replaced by angular speed universal coupling in recent years gradually owing to its non-isogonism speed drive characteristic.Fig. 3 is the structural drawing of a kind of three fork arm roller type angular speed universal couplings of producing of Germany, circumferentially the interval is provided with three cylindrical guiding grooves parallel with driven axle for 120 ° in driven axle tie-plate (8) upper edge, on radially three fork arms (9) of active coupling head, be with flat spherical roller (10), coupling is in transmission process, and spherical roller shows as sphere and contacts with the curved line of cylndrical surface in cylindrical guiding groove.This cylindrical guiding groove requires to have very high machining accuracy and certain quenching hardness, its result can cause processing difficulties and cost to improve.
The purpose of this utility model is that a kind of angular speed universal coupling by being convenient to after the improvement structure process and reduce cost will be provided.
The purpose of this utility model is achieved in that the joint shaft bearing (2) that belongs to standard piece is installed on three fork arms (7) of driving shaft coupling head (1), plunger (3) is housed on the joint shaft bearing (2), in the hole of driven axle tie-plate (4), stud with sleeve (5) for plunger motion, plunger (3) inserts in the sleeve (5), by the axial slip of plunger in sleeve (5) and the aligning effect of joint shaft bearing (2), make when between driving shaft coupling head (1) and driven axle tie-plate (4) axis angle being arranged, coupling still can carry out the transmission of isogonism speed.Thereby, organization plan of the present utility model require to have machining accuracy cylindrical guiding groove very high and that need to quench to realize providing a kind of Hooks coupling universal coupling of processing and reducing cost be convenient in the original structure because having cancelled.
Tripod Sliding Universal Joint provided by the utility model and three fork arm roller type angular speed universal couplings are relatively, since on the structure with the line way of contact between original spherical roller and the cylindrical guiding groove, be improved to the face contact between plunger and the sleeve and the face way of contact of joint shaft bearing, carry-over moment ability of the present utility model is obviously greater than three fork arm roller type Hooks coupling universal couplings.Owing to bush material of the present utility model is selected Babbitt for use and do not required quenching, because joint shaft bearing can selection standard spare, consequently reduced difficulty of processing, and cost reduces to some extent again.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Fig. 1 is the organization plan figure of the sliding angular speed universal coupling of three fork arms provided by the utility model.
Fig. 2 is the Tripod Sliding Universal Joint organization plan figure that the utility model provides, and is the right elevation of structure when driving shaft and driven axle dead in line shown in Figure 1.
The three fork arm roller type angular speed universal coupling structural drawing that Fig. 3 is produced for Germany in the prior art.
Describe sliding angular speed universal coupling CONSTRUCTED SPECIFICATION of three fork arms that provide according to the utility model and working condition in detail below in conjunction with Fig. 1 and Fig. 2.
Tripod Sliding Universal Joint provided by the utility model comprises a driving shaft coupling head (1) and a driven axle tie-plate (4), the splined hole at driven axle tie-plate (4) center connects with driven axle (6), an end of driving shaft coupling head (1) is the screw thread that connects with driving shaft, the other end is three warp-wise fork arms (7) at 120 ° at interval, it is characterized by and on three fork arms, be with joint shaft bearing (2) respectively, joint shaft bearing can use the existing standard part, a plunger (3) is housed on each joint shaft bearing, plunger inserts respectively in the sleeve (5), and three sleeves (5) are bumped into respectively in three axial cylindrical holes of even cloth of driven axle tie-plate (4).
In the course of the work, driving shaft drives driving shaft coupling head (1) and three fork arms (7), joint shaft bearing (2) is given in three fork arms (7) power transmission, and joint shaft bearing (2) is given sleeve (5) and driven axle tie-plate (4) by plunger (3) power transmission, orders about the driven axle constant speed at last and rotates.In transmission shown in Figure 1, when between driving shaft and driven axle (6) axis angle being arranged, plunger (3) slippage in sleeve (5), the land portions of joint shaft bearing (2) is waved, and three fork arms (7) are done small slip in joint shaft bearing.The axis angle of driving shaft and driven axle can reach 30 °.
Claims (2)
1, rotate the sliding angular speed universal coupling of three fork arms of transmission when being used for having between the axis of driving shaft and driven axle certain angle, comprise a driving shaft coupling head (1) and a driven axle tie-plate (4), the splined hole at driven axle tie-plate (4) center connects with driven axle (6), one end of driving shaft coupling head (1) is the screw thread that connects with driving shaft, the other end is three warp-wise fork arms (7) at 120 ° at interval, it is characterized by and on three fork arms, be with joint shaft bearing (2) respectively, joint shaft bearing can use the existing standard part, a plunger (3) is housed on each joint shaft bearing, plunger inserts respectively in the sleeve (5), and three sleeves (5) are bumped into respectively in three axial cylindrical holes of even cloth of driven axle tie-plate (4).
