Description

Technical Field

[0001] The utility model relates to the technical field of vertical circulation type three-dimensional parking equipment, in particular to a high-precision assembled toothed drive disc. Background Art

[0002] At present, vertical circulation three-dimensional garages on the market all adopt motor drive, but the transmission systems output by the motors are quite different. The transmission system is an important part of the vertical circulation three-dimensional garage, and its transmission efficiency and stability are important indicators for judging whether the vertical circulation three-dimensional garage meets the standards. Most of the current vertical circulation three-dimensional garages adopt a transmission system with a single transmission shaft. The motor directly drives the transmission shaft to rotate, and then drives the chain. The transmission chain is generally arranged on one side of the vertical circulation three-dimensional garage, and the car carrier plate is driven by the unilateral transmission system. The overall structure of this type is not balanced enough, and the stability is insufficient. After a long time, it is easy to cause an increase in the deviation of the transmission system, affecting the safe operation of the equipment. In addition, some parts on the drive disc cannot be replaced separately after being worn, resulting in high maintenance costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-precision assembled toothed drive disc to solve the problems raised in the background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A high-precision assembled toothed drive disc includes a chain plate driven by a motor. A toothed dial is coaxially arranged on the main shaft of the chain plate. The chain plate is fixed on the main shaft through a body plate. A lining plate is fixed on the left side of the body plate. The toothed dial is located on the right side of the body plate. A connecting sleeve is fixed between the body plate and the toothed dial, and a flange plate is also fixed between the connecting sleeve and the toothed dial.

[0006] In a further embodiment, the main shaft is connected and fixed to the lining plate, the body plate, the connecting sleeve, the toothed dial and the flange plate through a first flat key, and the flange plate and the toothed dial are connected and fixed through a second flat key and bolts.

[0007] In a further embodiment, the chain plate and the body plate form a drive disc, and the motor drives the chain plate through a transmission chain.

[0008] In a further embodiment, there are eight chain plates for each drive disc, and a plurality of bolt holes are formed on each chain plate. The holes at both ends of the chain plate are reamed holes.

[0009] In a further embodiment, the toothed dial and the chain plate are arranged parallel to each other.

[0010] In a further embodiment, the toothed dial is perpendicular to the main shaft.

[0011] In a further embodiment, the groove of the toothed dial is trapezoidal, and the projection of the cross-section of the groove of the toothed dial on a plane perpendicular to the axis of the toothed dial is in a straight line or involute shape.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The drive system adopts a double-sided drive mode. If the drive chain on either side breaks, the drive device on the other side remains in a transmission state with the motor brake, which can prevent potential tray falling accidents.
