Transmission device in vacuum high-temperature furnace

Abstract

The invention provides a transmission device in a vacuum high-temperature furnace. The transmission device comprises a supporting plate, a plurality of rolling shaft grooves, a plurality of bearing seats and a rolling shaft, wherein the supporting plate is in a rectangular plate shape; the plurality of rolling shaft grooves are formed in the supporting plate in parallel in the length direction ofthe supporting plate, the plurality of bearing seats are arranged at the two side ends of the supporting plate in the length direction of the supporting plate, the bearing seats are arranged at the two corresponding ends of the rolling shaft grooves correspondingly, and each bearing seat comprises an upper cover body, a lower cover body and side cover bodies arranged on the two sides respectively;the rolling shaft comprises a large shaft and small shafts arranged at the two ends of the large shaft, the large shaft is rotationally installed in the rolling shaft grooves, the small shafts are installed in the concave positions of bearings, transmission wheels are arranged at the outermost ends of the small shafts, and the transmission wheels are connected with driving wheels on an output shaft of a driving motor through chains. According to the transmission device, the upper cover bodies, the lower cover bodies and the side cover bodies arranged on the two sides are machined respectivelyand then assembled, and mounting of the bearings is facilitated.

Description

technical field [0001] The invention relates to the technical field of conveying platforms, in particular to a transmission device in a vacuum high-temperature furnace. Background technique [0002] The transmission environment in the vacuum furnace and vacuum coating equipment is very harsh, and they work under the condition of no grease and dust (most of the dust is generated during the furnace and coating process, which is unavoidable). The dust itself is tiny metal particles or alloy particles or ceramic particles. Once these particles enter the bearing, as they gradually increase, the bearing will be stuck. The bearing is often damaged due to the entry of dust, resulting in failure to work normally, reducing the life of the bearing and increasing production costs. Moreover, the traditional roller is locked in the bearing recess through the protrusion set at the entrance of the bearing recess. The upper opening of the bearing recess is slightly smaller than the lower en...

Problems solved by technology

The bearing is often damaged due to the entry of dust, resulting in failure to work normally, reducing the life of the bearing and increasing production costs

Moreover, the traditional roller is locked in the bearing recess through the protrusion set at the entrance of the bearing recess. The upper opening of the bearing recess is slightly smaller than the lower end. Although the installation is convenient, the production accuracy is not high. Assembly and disassembly The process is strong, it is easy to cause the bearing recess and the shaft part of the roller to wear, or even the shaft part to break, resulting in unreliable installation of the roller, which seriously affects the conveying stability of the roller conveyor device, and the product quality rate decreases
