9 technical requirements for CNC machining bearings

by xiaolong luo cnc machining shop

No matter what kind of work, there are certain requirements in terms of technology. If the technology is not good, then the effect made in the later stage will definitely not work, so if you want to ensure the effect of the product, then the technology must be excellent. In cnc machining, technology is divided into many parts. Today we come to understand how the technical requirements of bearings are?

1. Assembly rolling bearings are allowed to be heated by oil heating. The temperature of the oil must not exceed 100 ° C.
2. The semi-circular hole of the bearing outer ring, the open bearing seat and the bearing cover must not be stuck.
3. The outer ring of the bearing should be in good contact with the semi-circular hole of the open bearing housing and bearing cover. When inspected by coloring, it should be within 120 ° symmetrical to the centerline and 90 ° symmetrical to the centerline. Even contact. When checking with a feeler gauge within the above range, a feeler of 0.03mm must not be inserted into 1/3 of the outer ring width.
4. After the outer ring of the bearing is assembled, it should contact the end surface of the bearing cap of the positioning end evenly.
5. After the rolling bearing is installed, it should be flexible and stable to rotate by hand.
6. The joint surfaces of the upper and lower bearing pads should be closely attached, and cannot be checked with a 0.05mm feeler.
7. When fixing the bearing pads with positioning pins, drill the hinges and distribute the pins while ensuring that the tile mouth and end faces are flush with the opening and closing faces and ends of the relevant bearing holes. Do not loosen the pins after they are inserted.
8. The bearing body of the spherical bearing and the bearing seat should be in uniform contact. Check by coloring method, and the contact should not be less than 70%.
9. The surface of the alloy bearing lining is not allowed to use when it is yellow, and no nuclear separation is allowed within the specified contact angle. The area outside the contact angle should not be greater than 10% of the total area of the non-contact area.

Shaft parts are a common part type. Their structure is a rotating body, and the length is generally larger than the diameter. It is widely used in various mechanical equipment to support transmission parts, transmit torque and bear loads. Today we will talk about it here first.
