Abstract
The utility model device belongs to the preparation field of mechanical trade and is particularly applicable to a sliding bearing friction auxiliary device. The device comprises the lubricating antiwear elements which are respectively arranged between an axle seat and a turning shaft, and is characterized in that the axle seat is provided with a lubricating sleeve, the normal spring arranged between the lubricating sleeve and the turning shaft is tightly sleeved with the external diameter and is homophyly engaged with the inner diameter of the lubricating sleeve, the other end of the lubricating sleeve is provided with a positioning guard ring of the locking lubricating sleeve. After being underlaid with a thrust backstop cushion, the outside of the positioning guard ring is tightened with a locking female screw. Compared with the prior art, the sliding bearing friction auxiliary device of the utility model has the advantaged of simple and rational design structure, convenient device installation, convenient maintenance and unit replacement, and long device life time and the like.
Description
Affiliated field
The utility model device belongs to the preparation field of mechanical industry.Be specially adapted to the sliding bearing friction pair device in the machinery.
Background technique
In the machinery of prior art, because the device of sliding motion structure in this kind equipment generally is to adopt following dual mode: 1, be sliding bearing and rotatingshaft directly rub (being axle sleeve or bearing shell structure); 2, the sliding bearing of rolling structure is housed between axle bed and rotatingshaft in addition in addition.Though the device of above-mentioned sliding motion structure is still being used, but in use also there is following defective: because possible loss simple in structure increases, when adopting rotatingshaft (seeing accompanying drawing 1) as the friction pair main part, because of axle bed and rotatingshaft are to adopt unlike material prepared, after the load operation use, no matter must cause serious wear between axle bed and the rotatingshaft, be that arbitrary structures spare all can cause significant waste in replacing axle bed or the rotatingshaft.Also have in addition and on rotatingshaft, adopt heat or cold stationary fit that friction cover (seeing accompanying drawing 2) is housed, though being the loss when reducing the equipment critical piece and change, assembles by friction cover, but it is all very difficult when as installed or replacing friction cover, the service precision of restive equipment during for installation friction cover, when changing the friction cover because in long-term using process, caused cooperating more closely of axle and cover, institute so that axle and the folding that overlaps, adorn all very difficult.
Purpose and content
The purpose of this utility model is to propose a kind of structural design advantages of simple, and the installation, maintenance of equipment and part replacement are convenient, and economy and the long sliding bearing friction pair device of service life of equipment.
According to the purpose of this utility model, the sliding bearing friction pair device that we are designed, be the direct wear condition of master unit of equipment in changing prior art, solution is that the lubricating and wear-resisting pair is housed between axle bed and rotatingshaft, to avoid the loss of equipment master unit.3 come the utility model device is described in detail with reference to the accompanying drawings below, the utility model sliding bearing friction pair device is made up of the parts that lubricating and wear-resisting is housed respectively between axle bed 1 and the rotatingshaft 5, it is characterized in that in axle bed 1, being equipped with lubricating sleeve 2, it is that similar shape cooperates with lubricating sleeve 2 internal diameters that the positioning and locking that is equipped with between lubricating sleeve 2 and rotatingshaft 5 overlaps 4 external diameters, hold the positioning retainer ring 3 that locking lubricating sleeve 4 is housed in addition at lubricating sleeve 2, after positioning retainer ring 3 outsides are lined with retaining retaining pad 7, tighten locking nut 6 again.Other features of the utility model device also have the outer diametric plane of positioning and locking cover 4 to be provided with locating slot.The structure and the implementation result of the specific embodiment of further narrating this device below in conjunction with the accompanying drawing 3 and the accompanying drawing 4 of the utility model device.Can find out from accompanying drawing 3, external diameter at rotatingshaft 5 is equipped with positioning and locking cover 4, positioning and locking cover 4 is locked in (the rotation attrition surface is the plane) in the axle bed 1 with lubricating sleeve 2, the back-up ring 3 that is positioned simultaneously is locked in the lubricating sleeve 2, and, tighten locking nut 6 again and finish this Unit Installation by behind the firm positioning retainer ring 3 of retaining retaining pad 7 cards.In accompanying drawing 4, can see in addition, when positioning and locking cover 4 is locked in lubricating sleeve 2 in the axle bed 1, the rotation attrition surface of lubricating sleeve 2 can also be designed to arc shaped surface, when the rotation attrition surface of lubricating sleeve 2 is designed to arc shaped surface, the installation of rotatingshaft 5 and rotation can have certain inclination angle in setting range, and then the back-up ring 3 that is positioned is locked in the lubricating sleeve 2, and by behind the firm positioning retainer ring 3 of retaining retaining pad 7 cards, tightens locking nut 6 again and finish this Unit Installation.
Adopt the utility model sliding bearing friction pair device compared with prior art, have the structural design advantages of simple, equipment installation, maintenance and part replacement are convenient, and characteristics such as economy and service life of equipment length.This device has overcome prior art middle (center) bearing (bearing shell, axle sleeve) and has divided the situation of directly wearing and tearing with rotatingshaft, has guaranteed the integrity of main body part.In addition in the utility model sliding bearing friction pair device, when the rotation attrition surface of lubricating sleeve 2 is designed to arc shaped surface, this installation and rotation to rotatingshaft 5 is more reasonable, and under special operating conditions, rotatingshaft 5 can have certain work inclination angle in setting range simultaneously.Adopt the utility model device can also avoid making the more convenient and obvious reduction of the I﹠M labor intensity of equipment, improved the operating rate of producing owing to the disassemble or assemble difficulty that stationary fit produced.
Description of drawings
In above-mentioned specification:
Accompanying drawing 1 is rotatingshaft and the direct structural representation that weares and teares of axle bed in the prior art;
Accompanying drawing 2 is a prior art, and rotatingshaft is equipped with interior cover, the structural representation that is is directly worn and torn by interior cover and axle bed;
Accompanying drawing 3 is the utility model sliding bearing friction pair device embodiment's an assembly structure schematic representation;
