A Synchronous Transmission Mechanism for Roller Rod Furnace

Abstract

The invention discloses a synchronous transmission mechanism of a roller bar furnace, and belongs to the technical field of heat treatment furnace transmission mechanisms. The mechanism comprises twotransmission supports which are parallel to each other; an air pressure cylinder placing table is arranged on the left side of each of the two transmission supports, an air pressure cylinder is arranged on the end surface of the top of each air pressure cylinder placing table, a piston rod is inserted into the right side of each air pressure cylinder, a rotating connecting block is arranged on theright side of each piston rod, and the outer side of each rotating connecting block is movably connected to the left side of a driving rod; the right side of each driving rod is connected to a connecting shaft through a bearing, the other end of the connecting shaft is connected to a connecting rod, a connecting device is arranged on each connecting rod in a penetrating mode, and the other end ofthe connecting device is connected to a rotating wheel; and one rotating shaft is arranged between the middle parts of the front and back rotating wheels, each rotating shaft penetrates through the two side plates of the transmission supports, and a rotating roller is arranged on the outer wall, located between the two side plates of the transmission supports, of each rotating shaft. According tothe synchronous transmission mechanism, the structure is simple, the structure is easy to assemble and disassemble, the maintenance cost is low, and the synchronization precision is high.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms for heat treatment furnaces, in particular to a synchronous transmission mechanism for a roller furnace. Background technique [0002] In order to achieve the purpose of synchronous transmission, the traditional roller rod transmission mechanism adopts gear meshing for synchronous transmission. Dust is easy to enter between the gears, resulting in easy wear and short service life of the gears. Moreover, when the meshing of the gears is uneven, the wear of the gears will be accelerated, and the noise will be large. When the device needs to be repaired or replaced, the connecting keys in the gear connection need to be disassembled one by one. Due to the large pitch, the out-of-joint is caused, and the transmission efficiency of the worm gear is low, so it is not suitable for long-term continuous work under high power. For this reason, we propose a synchronous transmission mechanism ...

When the device needs to be repaired or replaced, the connecting keys in the gear connection need to be disassembled one by one. Due to the large pitch, the out-of-joint is caused, and the transmission efficiency of the worm gear is low, so it is not suitable for long-term continuous work under high power
