Embodiment

[0022] Such as figure 1 , figure 2 with image 3 As shown, the turntable of the present invention is mainly composed of a rotary support system, a drive system, a leveling system, and a deceleration and locking system. The rotary support system includes a base 14 and a rotating table 3 supported on the base 14. The body of the rotating table 3 is a revolving body, and a through hole is provided in the center as a seat hole. A cover plate 5 is provided on the upper end of the seat hole. 14 is connected with the rotary table 3 through the main shaft 9 and the bearing group arranged in the seat hole. Among the end faces of the ends, the end face of one end is a working plane, the upper surface of the cover plate 5 is flush with the working plane, and more than three trapezoidal grooves are symmetrically arranged in the center of the working plane, and the trapezoidal grooves are opened along the radial direction of the rotary table top 3, Each trapezoidal groove is equipped w...

Abstract

The invention relates to a turntable. The center of a rotary table of the turntable is provided with a through hole as a seat hole, a base is connected to the rotary table through a main shaft and a bearing set that are arranged in the seat hole, the main shaft is assembled in the central hole of the base, and the base at the outer side of the main shaft is arranged with a secondary plane thrust bearing; in the end surfaces of both ends of the rotary table, the end surface of one end is a working plane, and the end surface of the other end is supported by the secondary plane thrust bearing; afirst cylindrical step is also provided between the end surfaces of both ends of the rotary table, a main support body is arranged around the secondary plane thrust bearing on the base, a main plane thrust bearing is assembled between the main support body and the first cylindrical step, and three or more speed reduction slots are symmetrically arranged in the center on the big end ring surface ofthe first cylindrical step. A dual-rotary support system of the turntable is strong in loading capability, simple in structure, easy to manufacture and process, transport and install, and is specifically suitable for application under large-diameter fully loaded transportation condition.

Description

technical field [0001] The invention relates to the technical field of turntables, in particular to a turntable suitable for application under heavy load conditions. Background technique [0002] At present, some large parts of power generation equipment are mostly adjusted by lifting equipment in the process of assembly and maintenance. This method has certain safety risks, and at the same time, it is necessary to loosen and fasten the product parts before and after each adjustment of the installation posture, so the efficiency is relatively low. After the intelligent upgrade, in some situations where automatic assembly or automatic quality inspection needs to be realized by manipulators, it is difficult to achieve precise positioning by adjusting the installation posture of parts by lifting equipment. This application scenario is suitable for a servo turntable device. [0003] At present, there are many applications of turntables in the industrial field, but there are so...
