Description

[0002] Spline is a kind of mechanical transmission. It has the same function as flat key, semicircular key and oblique key, which are all used to transmit mechanical torque. There are longitudinal keyways on the surface of the spline shaft, and the rotating parts on the spline shaft also have corresponding keyways, which can keep rotating synchronously with the spline shaft. In order to avoid direct contact between steel parts when the spline shaft is matched with the spline sleeve, a layer of nylon coating needs to be covered on the surface of the spline shaft when the spline shaft is produced.

[0003] When coating the spline shaft, the spline shaft needs to be heated and immersed in a vulcanizing box filled with nylon powder, so that the nylon powder is melted by the heat and a nylon coating is formed on the surface of the spline shaft. When the spline shaft is taken out of the vulcanizing box, it is necessary to wait for the nylon coating on its surface to cool and solidify before the spline shaft can be removed from the device, resulting in low coating efficiency.
