Rotary spline is a kind of mechanical transmission, which transmits mechanical torque, has a longitudinal keyway on the surface of the shaft, and the rotating parts set on the shaft also have a corresponding keyway, which can maintain synchronous rotation with the shaft. At the same time of rotation, some can also be longitudinally sliding on the shaft, such as gearbox shift gears.
When we use some mechanical equipment, there will be some reasons for some part of the machinery to be damaged, rotary spline is widely used in mechanical equipment, is one of the most important parts, when it is damaged, how to repair it?
Weld overlay repair: Weld overlay is a method of repairing splines by stacking metal on worn parts. First of all, the worn parts are turned to remove the damaged metal, and then a layer of stainless steel, nickel-based alloy and other wear-resistant materials are stacked on its surface, which can effectively restore the size and performance of the spline and improve its wear resistance.
Spraying repair: Spraying repair is a method of spraying wear-resistant coatings, ceramic coatings and other wear-resistant materials on the wear parts by spraying technology, and the spraying materials can be selected according to the wear conditions, which is suitable for the repair of large-scale wear.
Brush plating repair: Brush plating is a method of coating metal or non-metallic materials on the wear part by electrolytic method, and the brush plating can be selected according to the working conditions of nickel, cobalt, copper and other materials, which is suitable for the repair of local wear.
Thermal spraying repair: Thermal spraying is a method of spraying wear-resistant materials on wear parts by flame or plasma technology, and thermal spraying can be used to select materials such as alumina and silicon carbide according to working conditions, which is suitable for repair under high-temperature wear conditions.
Adhesive repair: Adhesive repair is a method of using adhesive to bond worn parts together. The adhesive can be selected according to the working conditions, epoxy resin, polyurethane, etc., and is suitable for the repair of small area wear.
The above is about the commonly used repair methods after the ball spline is worn, and it still takes a certain process to repair the rotary spline. If you don't want to be so troublesome, you can re-purchase a new spline to replace, in order to reduce the time cost and let the machinery run normally, if you have other questions or purchase needs, you can contact us Taiwan high-tech consulting!
