Customer Questions : What is a non-contact backstop? What are its characteristics?
Technical answer
: Type non-contact backstop is a high-speed anti-reversal device with reliable backstop and smooth free operation. Its comprehensive mechanical performance is significantly better than other backstop devices due to its advantages such as jamming, large backstop torque, light weight, and easy installation.
Its internal structure uses a new type of special-shaped wedge with optimized design. In addition to being impact-resistant and having a large backstop torque, it also cleverly uses the centrifugal force of its own rotation: when the forward rotation speed of the input shaft is higher than the minimum speed, the internal working of the backstop It can achieve non-contact, zero wear and long service life.
Rotation direction of the inner ring. The code for the inner ring to rotate in the clockwise direction is code. The code for the inner ring to rotate in the counterclockwise direction is.
The following points should be noted when using non-contact backstop:
The working environment temperature of the backstop is d~+℃.
The temperature rise of the backstop should be lower than ℃ under normal working conditions.
. When the backstop is working under the rated backstop torque, pitting, plastic deformation and cracks shall not occur on the surface of the inner and outer rings of the wedge
. All parts must be inspected and qualified. Purchased parts must be qualified. Only after certification can assembly be carried out.
After assembly, the direction of rotation shown on the steering indicator plate should be consistent with the direction of rotation shown on the wedge assembly.
The exposed surface of the backstop should be coated with one layer of primer and two layers of topcoat.
The end surface paint of the inner ring of the backstop is red and the remaining outer surface paint color is milky yellow. Other colors can be used according to user requirements.
Note: and in the table are the minimum and maximum lengths required for the shaft extension to install the backstop respectively.
