Abstract

The invention provides a bearing for a mahjong machine and belongs to the technical field of bearings. The problem is solved that an existing bearing is inconvenient to manufacture and expensive to manufacture. The bearing for the mahjong machine comprises a rotating sleeve I, a rotating sleeve II and a positioning sleeve, wherein the rotating sleeve I, the rotating sleeve II and the positioning sleeve are all made of a plastic material, the positioning sleeve sleeves with the rotating sleeve I, and the positioning sleeve and the rotating sleeve I are clamp-connected and fixed to form a rotating body, the side wall of the positioning sleeve is provided with an annular convex edge I, and the side wall of the rotating sleeve I is provided with an annular convex edge II, an annular groove isformed between the annular convex edge I and the annular convex edge II, an annular convex edge III extending into the annular groove is formed in the side wall of the rotating sleeve II, and the rotating sleeve II and the rotating body can independently rotate. The bearing is light in weight and convenient to transport, the manufacturing cost of the bearing is obviously reduced by adopting the plastic parts compared with metal parts, a steel ball structure is also omitted, and the manufacturing cost of the bearing is further reduced, so that the manufacturing cost of the bearing is low.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a bearing for a mahjong machine. Background technique [0002] The mahjong machine is a common entertainment device in people's daily life. Its working principle is that the cards with the back of the mahjong tiles facing up are attracted by the magnetic ring on the shuffling barrel, and then rotate with the magnetic ring and transported to the conveying trough, and The machine head is pushed into pier by stacking pusher motor, and pushed away by the chain rod, so as to realize the automatic shuffling and loading of mahjong cards. There is a rotatable big disk inside the mahjong machine, and the use of bearings is required during the rotation of the big disk. Therefore, it is necessary to set a large disk bearing in the mahjong to support the rotation of the big disk. For example, a Chinese patent discloses a large plate mechanism and a silent mahjong machine [authorized announ...
