Problems solved by technology
[0002] More than 90% of the failure mode of the Oldham coupling is extrusion deformation, which leads to bearing wear, equipment vibration, and failure to work normally. However, at this time, only two contact surfaces of the coupling are deformed, and other parts are still intact.
In this way, there are two disadvantages. One is that the half-coupling and the Oldham are scrapped only because of the deformation of the contact surface, and the material is fully utilized; the other is that the half-coupling assembled on the shaft must be cut off by oxygen cutting. , it is very difficult to replace the half coupling, and the workload is quite large

Embodiment Construction
[0016] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention;
[0017] like figure 1 As shown, the technical solution of the preferred embodiment of the present invention is an Oldham coupling comprising: multi-groove half-coupling 1, multi-groove half-coupling 3 and Oldham 2;
[0018] Further, the multi-groove half-coupling 1 and the multi-groove half-coupling 3 are provided with three sets of grooves 4, 5, 6 at equiangular intervals;
[0019] The design principle of the present invention lies in: the design of the Oldham coupling, the difference between the multi-groove half coupling and the current coupling is that there are several more grooves with the same size and the same included angle as the original groove. The other dimensions are the same as those of the current half coupling; the size of the Oldham slider remains unchanged; the position of the keyway is determined according to the angle. The coupling in ...

The invention provides an Oldham coupling. The Oldham coupling comprises a multi-groove coupling half and a crosshead shoe and is characterized in that the coupling half is provided with a plurality of grooves and the crosshead shoe can continue to be used simply by being inserted into one of other grooves after one groove deforms through rotation, so that the service life of the coupling half is prolonged by multiple times when compared with that of an coupling half. The Oldham coupling reduces the maintenance workload, is long in service life, relatively decreases the frequency of replacement, greatly reduces the costs due to the fact that the multi-groove coupling half has the service life prolonged by multiple times only by being additionally provided with a plurality of grooves and meets the requirements of reliable, stable and long-time running under the conditions of high torque, large swing angle and harsh working conditions.
Description
technical field [0001] The invention relates to the field of couplings, in particular to an Oldham coupling. Background technique [0002] More than 90% of the failure mode of the Oldham coupling is extrusion deformation, which leads to bearing wear, equipment vibration, and failure to work normally. However, at this time, only two contact surfaces of the coupling are deformed, and other parts are still intact. In this way, there are two disadvantages. One is that the half-coupling and the Oldham are scrapped only because of the deformation of the contact surface, and the material is fully utilized; the other is that the half-coupling assembled on the shaft must be cut off by oxygen cutting. , It is very difficult to replace the half coupling, and the workload is quite large. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides an Oldham coupling to meet the requirements of reliable operation, stable operation and long ...
