Abstract

The invention relates to a transmission device which solves the technical problems that an existing middle transmission device in a reactor is large in size, large in occupied space, unreliable in power transmission and large in noise. The transmission device comprises a box body. An upper left bearing block, a middle left bearing block and a lower left bearing block are arranged on the left side of the box body from top to bottom, and an upper right bearing block, a middle right bearing block and a lower right bearing block are arranged on the right side of the box body from top to bottom. The middle left bearing block is connected with a third transmission shaft, and the upper left bearing block is connected with a first transmission shaft. The lower left bearing block is connected with a sixth transmission shaft, and the middle right bearing block is connected with a fourth transmission shaft. The upper right bearing block is connected with a second transmission shaft, and the lower right bearing block is connected with a fifth transmission shaft. A first gear, a middle gear and a fourth gear are arranged on the third transmission shaft. A second gear is arranged on the first transmission shaft, and an eighth gear is arranged on the sixth transmission shaft. A fifth gear is arranged on the fourth transmission shaft, and a third gear is arranged on the second transmission shaft. The transmission device can be widely applied to personnel lock gates.

Description

technical field [0001] The present invention relates to a transmission, in particular to a transmission for the middle of a personnel gate for a reactor. Background technique [0002] The personnel gate is the channel for operating and maintenance personnel to enter and exit the containment system during reactor shutdown, refueling and operation. In addition, the personnel gate can also be used for the transportation of small equipment, tools and instruments. [0003] The central transmission device is a key part of the transmission mechanism of the personnel gate, which has four main functions: [0004] 1. Transmit the power after the deceleration and torque increase of the motor to the inner and outer transmission boxes, and open the two sealed doors respectively; [0005] 2. Transfer the torque to manually open another door remotely; [0006] 3. Manually open the proximal door; [0007] 4. When working automatically or manually, transmit the force of locking or releas...
