Abstract
A knuckle support for adjusting and eliminating gap after wear and tear comprises a support, a suspension loop and an inner hole for arranging a bearing outer ring provided with an opening on the suspension loop, wherein, a bearing inner ring is arranged on a shaft of the support. The utility model is characterized in that the circumferentia of the inner hole is provided with an opening, the position of which is provided with an upper protruding part and a lower protruding part; the upper protruding part is provided with a threaded hole, while the lower protruding part is provided with a through hole; the suspension loop is provided with a governing screw which passes through the through hole and matches with the threaded hole of the upper protruding part. The utility model is mainly used for the connection of a servo-swaying actuator and a check bar.
Description
Technical field
The utility model relates to the electro-hydraulic servo linear actuator, relates in particular to the joint bearing on the electro-hydraulic servo linear actuator.
Background technique
The hangers of joint bearing is connected with the front-end and back-end of linear actuator, when carrying out dynamic fatigue test, be connected with bearing by test specimen, produced distortion by the stressed back of test specimen, producing small angle between joint bearing hangers and the bearing rotates, make sliding bearing Internal and external cycle surface of contact produce wearing and tearing, thereby produce the gap.Because the sliding bearing outer ring is to be installed in the bearing endoporus of joint, traditional joint bearing endoporus is a not opening of enclosed construction, can't realize the adjustment of diameter of bore size.
Summary of the invention
The utility model has proposed a kind of joint bearing that can adjust elimination wearing and tearing post gap at the deficiencies in the prior art.
This programme is realized by following technical measures: it comprises the endoporus that is used to be provided with the bearing outer ring of being with opening on bearing, hangers and the hangers, bearing inner race be arranged on the bearing the axle on, the periphery opening that it is characterized in that described endoporus, protuberance and following protuberance on opening is provided with, at last protuberance tapped hole is set, down protuberance is provided with through hole, passes the adjustment screw that described through hole cooperates with tapped hole on the last protuberance being provided with on the hangers.
The beneficial effect of this programme can be learnt according to the narration to such scheme, carry out pretension by adjusting screw, make between the Internal and external cycle of sliding bearing and outer ring and the hangers and reach no gap, adjust the aperture slots that screw can be regulated hangers owing to adopt the slit, when wearing and tearing generation gap appears in sliding bearing Internal and external cycle after operation after a while, can eliminate the slit by screwing the adjustment screw.Therefore the utility model has compared with prior art been realized technical purpose.
The concrete characteristics of this programme also have, and on described adjustment screw locking nut are set, and locking nut locking is avoided adjusting in the using process screw loosening.The hangers of joint bearing is provided with lubricating cup and is communicated with the oil circuit of lubricating cup and bearing enclose surface of contact, realizes lubricating the bearing surface of contact.Described bearing is the joint shaft bearing of outer ring opening, the unrestricted motion that joint shaft bearing can multi-angle, and having overcome traditional rolling bearing can only be in the drawback of single direction motion, thereby has realized the multivariant motion of parts, three-dimensional running.
