Ball screw support seat

1. What is a lead screw support seat?

The lead screw support seat is an important part of the connection between the lead screw and the motor, which can give full play to the functional advantages of the ultra-small support unit by virtue of high rigidity, high strength and stability, so that the mechanical equipment and bearings have a high-precision use effect during operation, and can also obtain very stable rotation performance.

2. the characteristics of the lead screw support seat

(1) Special bearing assembly that must be used in conjunction with ball screw.

(2) The 45° angular contact bearing is adopted, which has high rigidity and high precision, and can obtain stable rotation performance.

(3) The lead screw support is a small-volume design that considers the space around the installation, and the bearing with adjusted preload can be directly assembled, which reduces the assembly man-hours and improves the assembly accuracy.

Preparation before installation: Try to avoid occasions with large temperature changes and choose a clean place

Inspection of the lead screw and the lead screw support: confirm whether the surface of the lead screw and the inner circle part of the bearing in the lead screw support are tidy, and clean up if there is garbage and foreign matter. If there are burrs on the parts, please use an oil stone to grind them off and remove impurities such as cutting.

Assembling of the lead screw and the lead screw support: it should be inserted straight to avoid jamming; And pay attention to prevent the oil seal from shrinking, and can be pre-applied with grease to facilitate smooth insertion.

Accuracy confirmation: Confirm the amplitude and axial clearance of the lead screw shaft with a micrometer, and then tighten it in the order of ball screw nut, nut support, lead screw support seat, and support end lead screw support.
