Abstract
The utility model relates to a super short cross shaft universal coupling which is composed of two hollow cross shafts (3) and (8), two bearings (4) and (9), both outer fork heads (2) and (11) which are arranged at both sides and two spline housings (1) and (11) which are arranged at the middle part. Two inner fork heads (5) and (7) which are arranged at the middle part and a positioning shaft ring (6) are assembled by major parts, such as a duplex fork head, etc. which are assembled by screw bolts. Due to the adoption of a hollow cross shaft structure, an outer coupling sleeve of an outer fork head is extended inwards and is inserted in a cavity which is arranged at the middle part of the cross shaft, and the axial space is fully utilized. Consequently, a coupling appliance has relative minimum axial dimension. In addition, the utility model is suitable for some occasions, wherein, the installation position of which is limited.
Description
The utility model relates to a kind of universal coupling with spider that is used for transferring power, especially the short especially super-short universal coupling with spider of its axial dimension.
Big and bearing capacity height is widely used in numerous industrial departments such as automobile, Iron And Steel Industry, engineering machinery, rubber and plastics machine to universal coupling with spider because of its inclination angle allowable.But this kind coupling has the big shortcoming of axial dimension, thereby narrow its application of occasion is restricted in the mounting point, and for example the modifying rolling mill project of the many steel rolling mills of China selects Hooks coupling universal coupling to meet difficulty under the prerequisite of original installation dimension with regard to Chang Yin.
The purpose of this utility model is to propose a kind of super-short universal coupling with spider by improving existing universal coupling with spider structure, it has not only kept original advantage, but also overcome shortcoming, can enlarge its application area, make some be forced to use the occasion of gear coupling, even can replace with the super-short universal coupling with spider fully because of the mounting point restriction.
The purpose of this utility model is achieved in that the axial dimension that doublejointed is not had a cross axle part in the cross assembly (containing bearing) of the short type universal coupling with spider of indirect axle suitably extends, the structural type with cylindrical cavity is made at its middle part, and the axis of its cylindrical hole passes through the intersection point of two axis of cross axle, and perpendicular with the plane at two axis places.Cross axle has integrated type and combined type, and combined type is made up of an axle collar and four minor axises.Two hollow cross axles reach on the middle part duplex jaw that constitutes with two interior jaws of Bolt Connection by the outer jaw of bearings at two ends of installing on it.Outer jaw is made to have and is extended inward, the pattern of spline housing in the middle of inserting the outer coupling band in the cross axle mider hole and having slidably.Outer jaw is to be joined together by joining plate and two jaws by outer coupling band, and two jaws are relative, jaw and joining plate be connected with integrated type and combined type, combined type is to join together by screw and joining plate.The external cylindrical surface outboard end structure of middle spline housing has tape spool shoulder and band grooving to install two kinds of patterns of circlip for shaft.The spline flute profile can be rectangle and involute shape.Duplex jaw middle part is provided with set collar and straight end-face key, and uses Bolt Connection.Jaw has integrated type and combined type, and combined type adopts screw attachment.The utility model in use, spline housings link with input shaft and output shaft respectively in the middle of two.
Because the employing such scheme has not only made full use of the impossible axial space that utilizes of solid cross axle, thereby has reached the purpose that shortens this coupling axial dimension to greatest extent, and the spline housing transferring power also makes the installation adjustment convenient in the middle of adopting.
