Abstract
The utility model discloses a universal joint pin. The universal joint pin comprises a base body, a first pin body and a second pin body. A first plane and a second plane are formed on the surface of the base body and are in parallel. The first pin body is arranged on the first plane and the second pin body is arranged on the second plane. The first pin body is perpendicular to the second pin body. The center point of the first pin body and the center point of the second pin body are located on the same straight line. The first pin body and the second pin body are arranged on the two sides of the base body in a relatively staggered mode, so that the first pin body, the second pin body and the base body are located on the different cross sections, assembly space of the joint pin is increased, and installation and maintenance by workers are facilitated; in addition, the increased space can be used and a pin head of each pin body is sleeved with a bearing bush, so that bearings are well protected, abrasion to the bearings is reduced, and the service life of the joint pin is prolonged.
Description
Technical field
The utility model relates to a kind of coupling, more specifically say a kind of articulated cross shaft.
Background technique
Cross axle claims again crossed joint, and universal joint, is the component of machine of realizing varied angle transmission of power, and it is for changing the position of drive shaft axis direction, and it is drive system universal driving device " joint " parts.
Tradition articulated cross shaft, because matrix and spindle nose are arranged on same cross section, makes the space of its assembling and the amplitude of swing all very limited, very inconvenient to staff's installation and maintenance.On the other hand, the fault of cross axle is mainly that axle journal and Bearing Grinding undermine each axle journal and occur bending deflection, causes the center line of its each axle of cross axle not at grade, or two adjacent shaft centre line out of plumb.Trunnion journal and bearing wear excesssive gap due to cross axle, cross axle is in operation to produce and rocks, make center transmission shaft line depart from its rotation centerline, cause transmission shaft to produce the phenomenon of flutter phenomenon and transmission shaft generation abnormal voice in service, thereby cause the wearing and tearing of cross axle, affect the working life of cross axle.
Model utility content
The utility model is disclosed is a kind of articulated cross shaft, its main purpose is to overcome prior art above shortcomings and shortcoming, that is: the assembling of cross axle and the space of swing are very limited, be not used in installation and maintenance, the trunnion journal of cross axle and bearing wear excesssive gap on the other hand, easily cause the wearing and tearing of cross axle, affect its working life.
The technical solution adopted in the utility model is as follows:
An articulated cross shaft, it comprises matrix, the first axle body and the second axle body, the surface of described matrix forms two the first planes that are parallel to each other and the second plane; Described the first axle body is arranged in this first plane, and described the second axle body is arranged in this second plane, and described the first axle body is mutually vertical with the second axle body, and the central spot of the first axle body and the second axle body is on same straight line.
Further, the two ends of described the first axle body and the second axle body are respectively equipped with spindle nose.
Further, on described spindle nose, be also arranged with bearing housing.
Further, the central spot of described the first axle body, the second axle body and matrix is on same straight line.
By above-mentioned known to description of the present utility model, compared to the prior art, the utility model has the advantage of: stagger relative with the second axle body of the first axle body of the present utility model is arranged at the both sides of this matrix, axis body and matrix are on different cross sections, this has just increased the assembly space of cross axle, is more conducive to staff's installation and maintenance; On the other hand, we can also utilize the space of staggering and arranging and increasing, and to the sheathed bearing housing of the spindle nose on axis body, better protect bearing, reduce the wearing and tearing of bearing, thereby improve the working life of cross axle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is along the structural representation of A direction in Fig. 1.
Embodiment
Carry out with reference to the accompanying drawings to illustrate further embodiment of the present utility model.
As shown in Figure 1 and Figure 2, an articulated cross shaft, it comprises matrix 1, the first axle body 2 and the second axle body 3, the surface of this matrix 1 forms two the first planes 11 that are parallel to each other and the second plane 12, the first axle body 2 is arranged in this first plane 11, and the second axle body 3 is arranged in this second plane 12.
As shown in Figure 1 and Figure 2, the first axle body 2 is mutually vertical with the second axle body 3, and the central spot of the first axle body 2, the second axle body 3 and matrix 1 is on same straight line.At the first axle body 2 and the two ends of the second axle body 3, be respectively equipped with spindle nose 4, and be arranged with bearing housing 41 on spindle nose 4, bearing housing 41 is protection bearing better, reduces the wearing and tearing of bearing, thereby improves the working life of cross axle.
Stagger relative with the second axle body 3 of the first axle body 2 of the present utility model is arranged at the both sides of this matrix 1, and axis body and matrix 1 are on different cross sections, and this has just increased the assembly space of cross axle, is more conducive to staff's installation and maintenance; On the other hand, we can also utilize the space of staggering and arranging and increasing, and give the sheathed bearing housing 41 of spindle nose 4 at axis body two ends, and bearing housing 41 is protection bearing better, reduces the wearing and tearing of bearing, thereby improves the working life of cross axle.
Above are only embodiment of the present utility model, but design concept of the present utility model be not only confined to this, everyly utilize this design to carry out unsubstantiality to the utility model to improve, all should belong to the behavior of invading the utility model protection domain.
Claims (3)
1. an articulated cross shaft, is characterized in that: it comprises matrix, the first axle body and the second axle body, and the surface of described matrix forms two the first planes that are parallel to each other and the second plane; Described the first axle body is arranged in this first plane, and described the second axle body is arranged in this second plane, and described the first axle body is mutually vertical with the second axle body, and the central spot of the first axle body and the second axle body is on same straight line; The two ends of described the first axle body and the second axle body are respectively equipped with spindle nose.
2. a kind of articulated cross shaft according to claim 2, is characterized in that: on described spindle nose, be also arranged with bearing housing.
