Description

Technical Field

[0001] The utility model relates to the technical field of elevator traction wheels, in particular to an elevator traction wheel. Background Art

[0002] The elevator traction sheave is a key component in the elevator system. It is responsible for transmitting power so that the elevator car can move up and down. The traction sheave is usually made of high-quality steel or iron and has high wear resistance and fatigue resistance. The working principle of the traction sheave is to drive the movement of the elevator through the friction between the traction rope and the traction rope. The traction rope is wound in the groove of the traction sheave. When the traction motor drives the traction sheave to rotate through the traction reducer, the traction rope will move under the drive of the traction sheave, thereby driving the elevator car up or down. The design and manufacture of the traction sheave needs to comply with relevant safety standards and specifications to ensure the safety and reliability of the elevator operation. In addition, the maintenance and inspection of the traction sheave is also an important part of the daily maintenance of the elevator. Regular inspection and maintenance of the traction sheave can effectively extend its service life and ensure the normal operation of the elevator.

[0003] In the prior art, when an elevator traction wheel is installed on the outside of a motor shaft, bolts are usually used to fix it. However, since the thread groove is on the outside of the motor shaft, it is not convenient to align the thread groove on the motor shaft with the traction wheel during installation. In addition, there is no anti-corrosion measure for the bolts after installation. The bolts are easily corroded when exposed to the air. After the traction wheel has worked for a long time, the components connected to the traction wheel are prone to overheating, and the heat dissipation performance of the components connected to the traction wheel is poor. Therefore, an elevator traction wheel is proposed to address the above problems. Utility Model Content

At this time, the first thread groove can be aligned with the round hole, and the bolt is inserted into the round hole and screwed into the inner side of the first thread groove to complete the installation of the traction wheel body. Subsequently, the thread ring is screwed into the inner side of the second thread groove. At this time, the convex thorn pierces the baffle plate, and the anti-rust oil on the inner side of the oil storage cover can cover the bolt to prevent the bolt from contacting with the air and rusting. The engaging block and the engaging groove make it more convenient to align the first thread groove on the motor shaft with the round hole.

[0013] 2. In the utility model, the heat dissipation performance of the components connected to the traction wheel body can be improved by setting the third thread groove, thread block, fixed block and paddle. First, the thread block is screwed into the inner side of the third thread groove. When the traction wheel body is used, the motor shaft drives the fixed block and the paddle to rotate, and the paddle drives the air around the traction wheel to flow, thereby cooling the components connected to the traction wheel body.
