Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 2-6, a novel oil injection belt seal ring heavy load aligning belt seat bearing assembly, including bearing flange seat 6, first step mouth 10 has been seted up to the inner wall of bearing flange seat 6, second step mouth 11, first step mouth 10 diameter is greater than second step mouth 11 diameter, aligning roller bearing 5 has been placed in first step mouth 10, the one end that second step mouth 11 was kept away from to bearing flange seat 6 is through gland 1 shutoff, gland 1 is pressed and is established in aligning roller bearing 5 outer lane, annular oil storage tank 4 has been seted up to the circumference in bearing flange seat 6, oil storage tank 4 is located aligning roller bearing 5 outer circumference central point and is put, set up an oiling passageway 3 with oil storage tank 4 intercommunication on the bearing flange seat 6 at least, 3 open ends of oiling passageway are through-type pressure injection oil cup 2 shutoff.
An annular notch 9 is formed in the position of the second stepped port 11, a hole elastic check ring 7 is arranged in the notch 9, and a lip-shaped sealing ring 8 is arranged on one side, far away from the aligning roller bearing 5, of the hole elastic check ring 7 in a pressing mode.
The circlip for hole 7 is a circlip for hole B type 125, and the lip seal 8 is a lip seal B72.
The market price of the spherical outer surface self-aligning belt seat bearing with the same inner diameter and outer diameter is about 6 times that of the self-aligning roller bearing, and the service life of the spherical outer surface self-aligning belt seat bearing is far shorter than that of the self-aligning roller bearing. Taking the spherical surface self-aligning seated bearing UCFC217 and the self-aligning roller bearing 22217C as examples, the inner diameter is also 85mm, and the price of the UCFC217 bearing is more than 6 times that of the 22217C bearing. The UCFC217 basic dynamic load rating Cr1 is 83.5KN, and the self-aligning roller bearing 22217C basic dynamic load rating Cr2 is 362 KN. According to the bearing life formula L10 ═ (C/P)3,The ratio of the basic dynamic load rating of the self-aligning roller bearing 22217C to the basic dynamic load rating of the spherical outer surface self-aligning seated bearing UCFC217 is "a" ═ Cr2/Cr1 "═ 362KN/83.5KN ═ 4.34, so it can be calculated that the self-aligning roller bearing 22217C is 4.34 of the UCFC217 bearing life3The ratio is 81 times.
