Abstract

The invention relates to the technical field of bearings, in particular to a combined bearing which comprises an upper bearing and a lower bearing, and the upper bearing comprises an upper bearing outer ring and an upper bearing inner ring; one end of the upper bearing inner ring is an inner ring piece; the lower bearing comprises a lower bearing outer ring and a lower bearing inner ring; a shaft piece is arranged at the other end of the upper bearing inner ring, penetrates through the lower bearing inner ring and is locked on the lower bearing inner ring through a locking sleeve; and the upper bearing outer ring is tightly matched with the lower bearing outer ring. The combined bearing with the encoder further comprises an encoder assembly, the encoder assembly comprises a coded disc, a photoelectric assembly and an induction assembly, the coded disc is installed on the inner ring of the upper bearing, the induction assembly is installed on the inner bottom face of the outer ring of the lower bearing, the photoelectric assembly comprises a light source and irradiates the coded disc, and the photoelectric assembly is in circuit connection with the induction assembly. According to the technical scheme, the combined bearing is integrated, the installation links are reduced, the inherent precision of the bearing is ensured, the rotation stability is effectively improved, meanwhile, assembly and disassembly are convenient, maintenance is facilitated, the space is saved through the integrated structure, and the appearance is attractive.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing used for a bearing and a bearing with an encoder. Background technique [0002] Bearings are an important part of mechanical equipment, and the combination of encoders and bearings is becoming more and more widely used. Existing bearing encoders, such as figure 1 As shown, it includes a bearing and an encoder assembly. The bearing includes an upper bearing 1 and a lower bearing 2. The encoder assembly includes an encoder seat 6, a code disc 42, an induction component 43, a photoelectric component 41, a code disc support sleeve 9 and a copper shaft 7. And the protective cover 8, the photoelectric component 41 and the inductive part 43 are installed on the encoder, the copper shaft 7 passes through and is interference fit with the lower bearing 2, the encoder seat 6, the upper bearing 1 and the code disc support disc 9, and the code disc 42 Installed on the code disc su...
