specific Embodiment approach 1

[0019] Such as figure 1 , Figure 2, image 3 As shown, it includes a single-layer arc-shaped rack 1, a rotating disc 2, a center hole 3, a keyway 4, a single-layer arc-shaped tooth 5, a single-layer cylindrical roller 6, an outer ring hole 7, and an inner ring hole 8. The rotating disk 2 is parallel to the arc-shaped rack 1, and several single-layer cylindrical rollers 6 are evenly distributed in the circumferential direction of the rotating disk 2. The single-layer cylindrical rollers 6 are connected to the rotating disk 2 through angular contact bearings, and the single-layer cylindrical rollers The curved surface meshes with the profile surface of the single-layer arc rack 1 . The angular contact bearing can fix the axial displacement of the single-layer cylindrical roller 6, but does not affect the circumferential rotation of the single-layer cylindrical roller 6. Therefore, the forced movement of the single-layer cylindrical roller 6 on the profile surface of the single...

[0022] Such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, it includes double-layer arc-shaped rack 11, rotating disc 2, center hole 3, keyway 4, double-layer arc-shaped tooth 13, double-layer cylindrical roller 12, outer ring hole 7, inner ring hole 8, flower shaft 9. Roller sleeve 10. The rotating disc 2 is parallel to the double-layer arc rack 11, the rotating disc 2 is located between the double-layer arc teeth 13 of the double-layer arc rack 11, and several double-layer cylindrical rollers are evenly distributed on both sides of the rotating disc 2. Sub 12, the double-layer cylindrical roller 12 is connected with the rotating disk 2 through an angular contact bearing, and the curved surface of the double-layer cylindrical roller 12 meshes with the double-layer arc-shaped tooth 13 contour surface of the double-layer arc-shaped rack 11.

[0023] The double-layer cylindrical roller 12 is composed of a flower shaft 9 and a roller sleeve 10, and the two are mat...

Abstract

The invention provides a turntable roller arc teeth lifting mechanism. The mechanism comprises a rotatable round disk, cylindrical rollers, an angular contact bearing and arc racks, wherein the rotatable round disk and the arc racks are on the same plane; the plurality of cylindrical rollers are uniformly distributed at the peripheral direction of the rotatable round disk; each cylindrical roller is connected with the rotatable round disk through the angular contact bearing; the curve surface of each cylinder roller is meshed with the profile surface of the arc rack. The mechanism is large in transmitting power, high in efficiency and stable in work; the requirements on manufacturing and mounting precision are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting mechanism of arc-shaped teeth of a turntable roller. Background technique [0002] As a kind of lifting machinery, the lifting platform has been widely used in various workplaces such as logistics, handling, assembly, urban parking systems, and offshore oil fields. Its main function is to lift objects to different heights by means of the driving mechanism and the lifting mechanism. According to the different properties of the lifting mechanism, it can be divided into three categories: ① Rigid lifting mechanism, which mainly uses the rigid characteristics of the mechanism to directly lift or push the platform; ② Flexible lifting mechanism, mainly uses flexible components such as wire ropes and chains to pull The lifting of the platform is realized by means of dragging; ③ Rigid-flexible dual-attribute lifting mechanism, this type of mechanism has a rigid attribute when performing j...
