Abstract
The utility model discloses a combined type cross axle, which includes a rectangular axle (1), a round-shaped through-hole (2) is provided in the middle of the rectangular axle (1), a round axle (3) passes through the through-hole; bearing cups (4) are attached on both ends of the rectangular axle (1), the inner wall of the bearing cup (4) is in direct contact with the rectangular axle (1); bearings (5) are attached on both ends of the round axle (3). The cross axle of the utility model adopts a combined structure which not only facilitates installation, but also eliminates rollers between the cross axle and the bearing cup, so that the cross axle is in direct contact with the bearing cup, the diameter of the cross axle is increased, distribution of force bearing is uniform, the condition of local abrasion is not likely to occur, and life of the cross axle is effectively increased. The utility model has simple structure, low production cost, and great use effect.
Description
Technical field
The utility model relates to a kind of axle, especially a kind of combined cross shaft.
Background technique
At present, the cross axle master is mounted in the axle sleeve of coupling and fork and puts and use, and existing cross axle is a monolithic construction, very inconvenient when mounted; And, be connected by roller between existing cross axle and the bearing cup, for line contacts, the strength of cross axle part is increased between cross axle and the roller, the cross axle that weares and teares has easily influenced its working life; And the working life of axle, the diameter with axle had direct relation, and the diameter of cross axle must mate with the internal diameter of bearing cup of installing and rod post, therefore has been difficult to raising on the diameter of axle.
The model utility content:
The purpose of this utility model is: a kind of combined cross shaft is provided, and it is installed easily, and is not easy to wear, has increased the diameter of axle, has postponed working life, to overcome the deficiencies in the prior art.
The utility model is achieved in that combined cross shaft, comprises square shaft, is provided with the through hole of a circle at the middle part of square shaft, passes a circular shaft in through hole; Two ends at square shaft are connected with bearing cup, and the inwall of bearing cup directly contacts with square shaft; Two ends at circular shaft are connected with bearing.
Pass a step axle that replaces circular shaft in the through hole of square shaft, be connected with bearing cup at the two ends of step axle, the inwall of bearing cup directly contacts with the step axle.
On the inwall of bearing cup, be provided with oil groove.
On the axle body of circular shaft or step axle, be provided with spiral chute.
Owing to adopted technique scheme, compared with prior art, cross axle of the present utility model adopts fabricated structure, its not only makes things convenient for installs, and has cancelled the roller between cross axle and the bearing cup, and cross axle is directly contacted with bearing cup, increased the diameter of cross axle, and the stressed distribution that makes cross axle becomes evenly, is not prone to the situation of concentrated wear, has effectively increased the working life of cross axle.Of the present utility model simple in structure, fabricating cost is cheap, and using effect is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is an another kind of structural representation of the present utility model;
Accompanying drawing 3 is the structural representation of square shaft;
Accompanying drawing 4 is the structural representation of bearing cup 4.
Embodiment
When installing, because square shaft 1 can be dismantled with circular shaft 3 or step axle 6, therefore, can carry out independent installation respectively when mounted, make to install to become simple, adopt the mode of directly contact to be connected between the termination of cross axle and the bearing cup 4, therefore when making, the diameter of axle can be increased the size of 2 roller diameters, the working life of directly having improved axle; And oil groove 7 and spiral fluted to distribute be can obtain lubricatedly fully for the position that makes Spielpassung, avoided because dry and astringent and wearing and tearing that cause.
Claims (4)
1. a combined cross shaft comprises square shaft (1), it is characterized in that: be provided with the through hole (2) of a circle at the middle part of square shaft (1), pass a circular shaft (3) in through hole (2); Be connected with bearing cup (4) at the two ends of square shaft (1), the inwall of bearing cup (4) directly contacts with square shaft (1); Be connected with bearing (5) at the two ends of circular shaft (3).
2. combined cross shaft according to claim 1, it is characterized in that: in the through hole (2) of square shaft (1), pass a step axle (6) that replaces circular shaft (3), and being connected with bearing cup (4) at the two ends of step axle (6), the inwall of bearing cup (4) directly contacts with step axle (6).
3. combined cross shaft according to claim 1 and 2 is characterized in that: be provided with oil groove (7) on the inwall of bearing cup (4).
4. combined cross shaft according to claim 2 is characterized in that: be provided with spiral chute on the axle body of circular shaft (3) or step axle (6).
