Abstract
The utility model relates to an improved universal coupler, which mainly consists of a cross shaft and a fork head. The utility model is essentially characterized in that a group of upper and lower shaft neck vertical to the rotary central line of the cross shaft are arranged at the left section of the cross shaft body, and the other group of the front and rear shaft neck vertical to the rotary central line of the cross shaft are arranged at the right section of the cross shaft body. The two groups of shaft necks are not arranged on the same plane vertical to the rotary central line of the cross shaft; in this way, the universal coupler has large return obliquity meeting the requirements of large obliquity transmission, furthermore, the strength of the fork head machine is high, and the bearing strength of the coupler is high.
Description
The utility model is a kind of improved Hooks coupling universal coupling.
Be usually used in metallurgy industry milling train master now, the universal coupling with spider of auxilliary transmission, no matter be split type or whole fork head type, the mutually perpendicular two group axle journals of its cross axle on shaft center line: promptly organize axle journal up and down and front and back group axle journal all is positioned at same plane, at 45 with the adjacent occlusal surface of these two groups of joining two jaws of axle journal, leave the revolution inclination angle that the gap forms jaw in the middle of it, this revolution inclination angle is restricted, and can't satisfy the needs of large inclined angle transmission, the bearing strength of this jaw mechanical strength and coupling is all lower simultaneously, and working life is low and reliability is relatively poor.
The purpose of this utility model is a kind of improved antarafacial universal coupling with spider of design, two groups of axle journals of its cross axle are not at grade, make the jaw that links with these two groups of axle journals obtain bigger inclination angle, can satisfy the needs of large inclined angle transmission, and jaw has higher mechanical strength, and coupling has higher bearing strength.
The purpose of this utility model is achieved like this: in the left side of the cross axle axis body of coupling section, be provided with one group with the perpendicular upper and lower axle journal of cross axle rotation centerline, and the right section of axis body be provided with one group also with the perpendicular front and back axle journal of cross axle rotation centerline, these two groups of axle journals are respectively charged in the bearing hole of each jaw, such coupling can satisfy the needs of large inclined angle transmission because its jaw has bigger inclination angle, and the jaw mechanical strength is higher, and the bearing strength of coupling is also higher.
It is simple in structure that the utility model is carried the antarafacial universal coupling with spider, safe and reliable, and the life-span is long, is particularly useful for the transmission of power of large inclined angle.
Now in conjunction with the accompanying drawings the utility model being carried the antarafacial universal coupling with spider is further described:
Fig. 1 is the schematic representation that the utility model is carried antarafacial Cardon universal joint coupling;
As can be seen from Figure 1, the utility model is carried antarafacial Cardon universal joint coupling mainly by jaw 1,4,8,9, a left side, right cross axle 3,10, inner ringless roller bearing 5, elasticity endoporus jump ring 7 compositions such as grade, the left side section that is primarily characterized in that the axis body 11 of left cross axle 3 is provided with axle journal 2 and following axle journal 12 on one group, and axle journal 2,12 is perpendicular with the rotation centerline of axis body 11, axle journal 6 and back axle journal 13 (not drawing among the figure) before the right section of the axis body 11 of cross axle 3 is provided with one group, this front and back axle journal 6,13 is also perpendicular with the rotation centerline of axis body 11, axle journal 2,12 and axle journal 6,13 be not positioned at the perpendicular same plane of axis body 11 rotation centerlines on, on cross axle 3, following axle journal 2,12 and front and back axle journal 6,13 pack in the bearing hole of jaw 1 and 4 with inner ringless roller bearing 5 respectively, then again all with elasticity endoporus jump ring 7 location, the axle journal up and down of same right cross axle 10, the front and back axle journal is the same with cross axle 3 with the structure of axis body, be not positioned on the perpendicular plane of same and axis body rotation centerline, with the axle journal of right cross axle 10 respectively with inner ringless roller bearing 5 jaw 8 of packing into, locate in 9 the bearing hole and with elasticity endoporus jump ring 7, can be made into integrated type between the jaw 4 and 8, welding type also can adopt forms such as flange or spline to be coupled to each other, so just be assembled into the antarafacial universal coupling with spider, this coupling does not disturb when rotating owing to jaw 1 and 4 mutually, has bigger revolution inclination angle, when importing through jaw 9 outputs by jaw 1, power just obtained the transmission of large inclined angle, and each jaw 1,4,9,8 all have higher mechanical strength, and whole coupling also just possesses higher bearing strength;
As above-mentioned upper and lower axle journal 2,12 and front and back axle journal 6,13 are made single shaft respectively, axis body 11 made to have be not positioned on the same plane vertical and the drive block of mutually perpendicular two through holes, can realize the large inclined angle transmission of power equally with the coupling that jaw 1 and 4 assembles with axis body 11 rotation centerlines.
Claims (2)
1. one mainly by jaw (1), (4), (8), (9), left and right cross axle (3), (10), and the antarafacial universal coupling with spider that inner ringless roller bearing (5), elasticity endoporus jump ring (7) etc. are formed is primarily characterized in that:
A. go up the left side section that axle journal (2) and following axle journal (12) are positioned at the axis body (11) of cross axle (3), and perpendicular with the rotation centerline of axis body (11);
B. preceding axle journal (6) and back axle journal (13) are positioned at the right section of the axis body (11) of cross axle (3), and be also perpendicular with the rotation centerline of axis body (11);
C. upper and lower axle journal (2), (12) and forward and backward axle journal (6), (13) are not positioned on the perpendicular same plane of rotation centerline with axis body (11).
2. antarafacial universal coupling with spider according to claim 1, it is characterized in that: upper and lower axle journal (2), (12) and forward and backward axle journal (6), (13) are made single shaft respectively, and axis body (11) is made to have and is not positioned on the perpendicular plane of same and axis body (11) rotation centerline and the drive block of mutually perpendicular two through holes.
