Abstract
The utility model discloses a rolling-needle-free heavy-load universal joint of a universal coupling, belongs to the universal joint matched with the universal coupling, and aims to provide the universal joint which is good in lubrication condition, slight in abrasion, long in service life and low in noise. The universal joint comprises a universal joint body, joint sleeves and oil seals, wherein the joint sleeves adopt cup-shaped structures and are arranged on all joint necks of the universal joint body, the oil seals are fixed on all the joint necks and seal joint sleeve openings, and a spiral oil guide groove (2) is formed in each joint neck. According to the universal coupling, lubrication conditions of the joint necks and the joint sleeves are improved, the friction between the joint necks and the joint sleeves is reduced, and the bearing capacity of the universal joint is improved; the universal joint has the advantages of simple structure, convenience in assembly, high bearing capacity and the like and is a rolling-needle-free universal joint applied to the universal coupling.
Description
Technical field
The utility model relates to a kind of Hooks coupling universal coupling, relates in particular to a kind of cross axle of Hooks coupling universal coupling.
Background technique
As everyone knows, cross-axle universal shaft coupling is to be connected between dynamic power machine and work mechanism, for a kind of mechanical transmission of transmitting torque.Because Hooks coupling universal coupling has the large and transmission efficiency advantages of higher of larger angle compensation ability and bearing capacity, at Heavy duty maching industries such as metallurgy, mine, oil, boats and ships, coal, rubber, papermaking equipments, be used widely.
Cross axle is the critical component of Hooks coupling universal coupling, in order to reduce the wearing and tearing between cross axle and coupling hook, on the axle journal of cross axle, conventionally all needle bearing will be set; This bearing consists of overcoat, the needle roller that is built in overcoat.Because needle roller diameter is little, with axle journal or outer casing inner wall surface of contact little (line contacts); Therefore the load that needle roller bears is larger, and easily wearing and tearing, working life are short.In addition, the cross axle of this needle-type not only complex structure, assemble cumbersome, and because needle roller need to occupy certain space; Therefore under the prerequisite that keeps universal joint volume not increase, can only dwindle the axle journal diameter of cross axle, thereby cause the intensity of cross axle lower, finally cause cross-bearing loading capability to decline.Moreover, because traditional needle-type cross axle is rolling friction, therefore also there is vibration and the large defect of noise.
For this reason, application number is that the utility model patent that " 201310219957.0 ", name are called " a kind of Hooke's joint without needle roller " discloses a kind of without needle roller cross axle, although this patent overcome needle-type cross axle some intrinsic defects, improved the bearing capacity of same model cross axle, but because lubricating condition is poor, therefore wearing and tearing are comparatively serious, working life is still shorter, and noise is also larger.
Summary of the invention
For the above-mentioned defect existing in prior art, the Hooks coupling universal coupling that the utility model aims to provide that a kind of lubricating condition is good, wearing and tearing are slight, long service life, noise are little is without needle roller heavy duty cross axle.
To achieve these goals, the utility model by the following technical solutions: it comprises cross axle body, be located at the axle sleeve of cup-shaped structure on this each axle journal of cross axle body, be fixed on described in each on axle journal the oil sealing of this axle sleeve mouth sealing; Described in each, axle journal is provided with spiral oil guide slot.
End face at each axle journal is provided with the groove being communicated with oil guide slot; Interior edge face at each axle sleeve is provided with the shoe cream room being communicated with groove, and the exterior edge face of each axle sleeve is fixed with the pump nozzle being communicated with this shoe cream room; Each groove is decussate texture in cross axle body oil duct by being built in is interconnected.
Compared with the prior art, the utility model is owing to having offered spiral oil groove on the axle journal of cross axle, therefore can between axle journal and axle sleeve, form the oil film that is similar to sliding bearing, not only improve lubricating condition between axle journal and axle sleeve, alleviated friction between the two, reduced noise, extended working life, and improved cross-bearing loading capability.Owing to being provided with groove and shoe cream room, therefore lubricated more abundant; Owing to having adopted the cross oil duct that each groove is communicated with, even if therefore part pump nozzle stops up that also to guarantee that each axle journal obtains good lubricated, and all directions all can charging-up lubricant oil, very convenient.The utlity model has the advantages such as simple in structure, easy to assembly, bearing capacity is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: oil duct 1, oil guide slot 2, cross axle body 3, oil sealing 4, axle sleeve 5, pump nozzle 6, shoe cream room 7, groove 8.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: the axle sleeve 5 of four cup-shaped structures is enclosed within respectively on each axle journal of cross axle body 1 by the mode of Spielpassung, the root at described axle journal is fixed with the oil sealing 4 of axle sleeve 5 port closeds; On the cylndrical surface of each axle journal, be distributed with spiral oil guide slot 2.
Can smooth and easy inflow oil guide slot 2 for the ease of lubricating oil, at the end face of each axle journal, offer the groove 8 being communicated with oil guide slot 2; For the ease of storing lubricating oil, guarantee fully lubricatedly, at the interior edge face of each axle sleeve 5, offer the shoe cream room 7 being communicated with groove 8; For the ease of charging-up lubricant oil, in the exterior edge face of each axle sleeve 5, be fixed with the pump nozzle 6 being communicated with shoe cream room 7.For fear of some pump nozzle 6, causing can not charging-up lubricant oil, is provided with the cross oil duct 1 that each groove 8 is interconnected in cross axle body 3 inside.
