Elevator door lock roller elevator spare parts 45*15*12 OD45mm W15mm ID12mm DK-RSL-RN4

Function:
Reducing friction: During the opening and closing process of the elevator door, the door lock roller and the door lock hook cooperate with each other, which can effectively reduce the friction generated when the door lock hook moves, making the door lock move more smoothly and reducing the wear of components.
Transmitting power: When the elevator car door knife moves, it will drive the floor door lock roller on the floor door device, thereby realizing the opening and closing of the elevator floor door. In this process, the door lock roller plays a key role in transmitting power.
Ensuring the synchronization of the door: It helps to ensure the synchronization of the car door and the floor door during the opening and closing process, so that the two doors can move in a coordinated manner to avoid asynchrony, thereby ensuring the safety of passengers and the normal operation of the elevator.

Installation and debugging:
Installation location: The door lock roller is generally installed on the door lock device of the elevator floor door, corresponding to the door knife installed on the car door. A certain gap needs to be maintained between the two to ensure that they can work normally during the operation of the elevator.
Debugging points: After the installation is completed, the door lock roller needs to be debugged. First, check whether the position of the door lock hook and the door lock roller is accurate, and ensure that when the elevator door is fully closed, the door lock hook can accurately contact the door lock roller; secondly, adjust the pressure of the door lock roller so that it can ensure the smooth movement of the door lock hook, and will not cause the door lock hook to fail to accurately contact the door lock roller due to too little pressure.
Maintenance and maintenance:
Regular inspection: Elevator maintenance personnel should regularly check the door lock roller to see if it has damage such as wear, deformation, cracks, etc., and whether the roller rotates flexibly. If problems are found, the relevant parts should be replaced or repaired in time.
Cleaning and lubrication: Clean the door lock roller regularly to remove dust, oil and debris on the surface to ensure its normal operation. At the same time, you can apply some special lubricant to further reduce friction and extend the service life of the door lock roller.
