Abstract
The utility model provides a cylindrical case for a telescopic constant velocity universal joint. The cylindrical case comprises a groove case body and a groove case handle. The groove case body and the groove case handle are formed in a solid forging mode. Six arc groove roller ways uniformly distributed and connected are arranged in the groove case body. The exterior of a groove case is cylindrical. A step and an inclined face are arranged between the groove case body and the groove case handle. The arc groove roller ways in the groove case body extend inwards to form enough telescopic space. A bottom groove is formed in the groove case body. The cylindrical case has the advantages that the structure is simple, the strength is high, breaking can not be caused easily in the use process, the requirement for the universal joint is low, and inner parts do not fall off.
Description
Technical field
The utility model relates to a kind of cylinder outer race of Telescopic constant-velocity universal joint, belong to vapour vehicle component technical field.
Background technique
In prior art, the three ball pin style universal joint of conventional construction, its housing body has three ditches that diameter is less, and what be mated is traditional three ball pin bearings (have three groups be uniformly distributed shape ball and with punching press back-up ring and clip spring structure).Chinese patent discloses a kind of tripod type constant velocity joint (notice of authorization number: CN100557258C), it comprises: housing, there are three rail slots, these three rail slots be limited at along circumferential trisection housing position on, and radially extend: spider, there are three polyhedron gudgeons, these three polyhedron gudgeons are formed at projectedly along on the position of circumferential trisection spider, to insert respectively the rail slot of three cotter way shells, and each this polyhedron gudgeon has at least two polygon surfaces; Interior roller, the circumferential inner surface of each this interior roller has for the curved surface profile around polyhedron gudgeon; Multiple needle rollers, the circumferential outer surface of each interior roller of assembling; And outer roller, each this outer roller is formed as rotating by needle roller, moves upward, and move on the axle of the rail slot along housing slideway is each with the axle at interior roller; The summit of each gudgeon is polished into selected circular surface, so that the polishing part of the circumferential inner surface of each interior roller and each gudgeon contacts at the mutual face of diverse location; Non-contact bight is formed between the contact segment of gudgeon, can offer reliably so that profit is rolled agent the part of carrying out limited relative movement; Retaining ring and fixing clamp, this retaining ring and fixing clamp are installed as with needle roller and outer roller and separate and allow this needle roller and the outer roller distance of sufficient movement vertically, to prevent that needle roller from separating with outer roller; For preventing that the standing part entirety that needle roller separates with interior roller from having formed in one end of the circumferential outer surface of each interior roller; And retaining ring and fixing clamp are installed to the other end of the circumferential outer surface of each interior roller, so that they divide and allow this needle roller and the distance of interior roller along outer Roller Shaft to sufficient movement with needle roller and interior roller.But the housing intensity that this universal joint adopts is poor, this structure is difficult for heat radiation, and too complicated to the requirement of universal joint, product too complexity easily has problems.
Model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of Telescopic constant-velocity universal joint cylinder outer race, it can solve prior art exist housing intensity poor, when use, easily rupture, universal joint is required to too complexity simultaneously, easily produce inner body and drag the technical problems such as the peaceful accident of initiation.
The purpose of this utility model is solved by following technical proposals: described Telescopic constant-velocity universal joint cylinder outer race, it comprises pot shell body and pot shell shank, described pot shell body and pot shell shank are that solid forging forms, pot shell body interior is provided with six arc groove raceways that are uniformly distributed and be connected together, and pot shell outside is made as cylindrical.
Between described pot shell body and pot shell shank, be provided with step and inclined-plane, the arc groove raceway of pot shell body interior has extended internally to form enough extendable rooms, is provided with kerve in pot shell body interior.
The utlity model has simple in structurely, intensity is good, and easy easy-rupturing not when use requires simply to universal joint, and inner body such as can not drag at the feature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, described Telescopic constant-velocity universal joint cylinder outer race, it comprises pot shell body 4 and pot shell shank 3, described pot shell body 4 and pot shell shank 3 form for solid forging, pot shell body 4 inside are provided with six arc groove raceways 1 that are uniformly distributed and be connected together, and pot shell outside is made as cylindrical 6.
Between described pot shell body 4 and pot shell shank 3, be provided with step and inclined-plane 2, the arc groove raceway 1 of pot shell body 4 inside has extended internally to form enough extendable rooms, is provided with kerve 5 in pot shell body 4 inside.
Embodiment: in pot shell body 4, star wheel is housed, between star wheel and pot shell body 4 inside, be arranged with six steel balls by the transmission of power of speed changer on axle.Telescopic constant-velocity universal joint cylinder outer race is forged and is formed by 20CrMnTi material, therefore intensity is higher, and between pot shell body 4 and pot shell shank 3, be provided with step and inclined-plane 2 and more can effectively ensure the phenomenon of rupture of pot shell body 4 and pot shell shank 3, simultaneously can bear larger power, be difficult for twisting off, fracture, long service life
Described pot shell body 4 inside are provided with kerve 5, and kerve 5 can prevent that bottom surface and star wheel end face from interfering, and can also reduce the weight of material, have also increased inner space thermal diffusivity good etc.
Be provided with six arc groove raceways 1 in pot shell body 4 inside, it is stressed even in movement process that it changes six raceways into, simple to the claimed structure of body interior annex.
The utility model is provided with six arc raceways and the outside length that is made as cylindrical and has increased arc raceway in pot shell body 4 inside, distribute more uniformly suffered dynamics and pot shell body exterior of six arc raceways is provided with cylindrical and increased inner and outside thickness, increased the serviceability of product, the length that has increased circular arc road has stretchability to be turned to more flexibly product and stretches.
When use, in Telescopic constant-velocity universal joint cylinder outer race, packing jump ring, transmission shaft, retainer, star wheel, steel ball, back-up ring into can use.
Claims (2)
