Split cage for linear motion device

Abstract

The application relates to the technical field of linear motion devices, in particular to a split type retainer of a linear motion device, which comprises a guide rail and a sliding block, two return covers, two retainer assemblies, a retaining strip and four through holes. The two return covers are respectively arranged at the two ends of the sliding block. The two retainer assemblies are respectively arranged at the two sides of the guide rail. Each retainer assembly comprises the retaining strip which is inserted on the two inner side walls of the sliding block, and a rolling body groove is formed between the retaining strip and the sliding block. The rolling body groove is located at the upper and lower sides of each retaining strip. The four through holes are arranged on the sliding block, are located at the two sides of the guide rail and are located at the upper and lower sides of the retaining strip. The first pipe is inserted with one end of the retaining strip. The second pipe is inserted with the other end of the retaining strip. The pipes are respectively inserted with the retaining strip from the two ends of the sliding block, so that the installation between the pipes and the sliding block is realized, the machining difficulty of the sliding block is reduced, and the assembly efficiency of the sliding block is improved.
