Embodiment 1

[0031] An accurate positioning coupling provided by the present invention, refer to Figure 1 to Figure 5 , including a spline shaft 1 that runs through the entire coupling, the spline shaft 1 is provided with an upper mounting position 1a compatible with the upper bearing 81, and a lower mounting position 1a compatible with the lower bearing 82 1b, a boss-shaped turning surface is formed between the two mounting positions, and the upper bearing 81 and the lower bearing 82 are respectively clamped and assembled on the above-mentioned two locking positions on both sides of the boss-shaped turning surface. Wherein, the upper bearing 81 is preferably an upper deep groove ball bearing, and the lower bearing 82 is preferably a lower deep groove ball bearing.

[0032] During assembly, the two bearings are assembled from the left and right directions of the spline shaft 1, which reduces the requirement on concentricity during assembly and facilitates the installation of the bearings....

Abstract

The invention discloses an accurate positioning type coupler and an assembling technology, aims at providing a coupler accurate in positioning and convenient to install, and belongs to the technical field of mechanical transmission part design. According to the technical scheme, the accurate positioning type coupler comprises a spline shaft, the spline shaft is provided with an upper installing clamping position matched with an upper bearing, and a lower installing clamping position matched with a lower bearing, a boss-shaped revolution surface is formed between the two installing clamping positions, and the upper bearing and the lower bearing are clamped and assembled at the two clamping positions on the two sides of the boss-shaped revolution surface respectively. The upper bearing and the lower bearing are sleeved with a bearing sleeve, the two ends of the bearing sleeve are fixedly provided with an upper end cover and a lower end cover respectively, and the upper end cover is connected with an upper end cover sleeve.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an accurately positioned shaft coupling, and also relates to an assembly process of the shaft coupling, which belongs to the technical field of mechanical transmission parts design. Background technique [0002] Couplings are widely used in mechanical, hydraulic and other transmission fields. They are mainly used for the connection between shafts. Generally speaking, due to reasons such as processing machine tools and manufacturing costs, the manufacturing size of the shaft should not be too long. Therefore, the transmission rotation In the process of movement, sometimes at least two shafts are needed, and the coupling is used to connect the shafts and has a good performance of transmitting rotational motion. [0003] However, for the couplings currently on the market, it is difficult to locate between the shaft and the bearing during installation, and the installation is relatively difficult;...
