Rotating support of rotary platform

Abstract

The invention aims at providing a rotating support of a rotary platform. The rotating support is used for the rotary platform and comprises an upper raceway face, a lower raceway face and a roller mechanism installed between the upper raceway face and the lower raceway face, the roller mechanism rolls relative to the upper raceway face and the lower raceway face so that the upper raceway face can rotate relative to the lower raceway face, and the rolling path of the roller mechanism is limited. The rolling path of the roller mechanism is limited through a center shaft. By means of the rotating support, the roller mechanism rotates around the center shaft, the rolling path of the roller mechanism is limited while rolling friction is achieved, and the purposes of low rotating resistance and high rotating precision are achieved.

Description

technical field [0001] The invention relates to the field of mechanical transportation, more specifically, to the technical field of slewing bearings for rotating platforms. Background technique [0002] In the field of mechanical manufacturing, such as automobile manufacturing, it is necessary to use a rotary table. In order to realize material movement more conveniently, a mechanical rotating platform for automatic switching between empty material and full material can be designed. [0003] Figure 5 Disclosed is a schematic diagram of a rotating platform with bins running. After the operator finishes using the parts in the bin B, he starts to release the positioning mechanism of the rotary platform. Since the rotating platform in this embodiment has a certain inclination, the full material box A located at the high position and the empty material box B located at the low position can drive the rotating platform toward the direction from the high direction to the bottom ...

Problems solved by technology

However, this kind of support wheel type slewing bearing also has obvious defects. Due to the lack of a fixed guiding mechanism during the rolling process of the support wheel 202, unlike the rolling element type slewing bearing, the rolling body rolls in a fixed track, so the support wheel 202 The rolling degree of freedom of the slewing bearing is relatively large, which is easy to cause deviations in the rotation of the slewing bearing, resulting in low precision of the slewing bearing, and its use is limited in occasions requiring higher slewing precision.

Moreover, the poor precision of the slewing bearing will shorten the service life of the slewing bearing

In addition, since an additional bracket 204 for installing support wheels is required between the upper structure 206 and the lower structure 208 of the supporting wheel slewing bearing, the application field of the rotating platform with low horizontal height is limited to a certain extent.
