Abstract
The utility model relates to a cross sliding block shaft joint includes that: a cross sliding block shaft joint formed by two half shaft joints and a medium cross sliding block divides each half shaft joint into two halves which are the upper half part and the lower half part of the shaft joint; the two halves are fixed firmly through a screw thread and are combined into a whole; the combining surface between the two halves is through an axes of the half shaft joint and is positioned through a positioning pin. Therefore, the utility model discloses also a divided type shaft joint. Through the improvement, the previous performance of the cross sliding block shaft joint in the transmission shaft transferring torque; besides, the cross sliding block shaft joint has the advantages of convenient and fast assembly and disassembly, easy maintenance and accident handling, a simple structure and easy processing.
Description
Affiliated technical field
The utility model relates to coupling, or claims shaft coupling, particularly a kind of be connected in transmit the sliding cross coupling of using than high pulling torque between live axle and the driven shaft.
Background technique
Coupling commonly used is a closed coupling.Be the decentraction of compensation two transmission shafts in transmission, and adopt sliding cross coupling.The half-coupling of sliding cross coupling is with live axle axle head, the installation of driven shaft axle head the time, and the employing hot charging is joined, interference fit.When the half-coupling of sliding cross coupling and when component on the transmission shaft of half-coupling being housed being damaged, change and keep in repair comparatively difficulty of this part component.For example, in the washing appliance of colliery coal preparation plant, just there is this situation in the sliding cross coupling that is usually used between speed reducer output shaft and the equipment.
Summary of the invention
In order to overcome the deficiency of existing sliding cross coupling mounting or dismounting inconvenience, the utility model provides a kind of improved sliding cross coupling, this coupling not only can guarantee the performance of former sliding cross coupling, and the mounting or dismounting on transmission shaft become convenient and swift, and maintenance and accident treatment become easy.
The utility model is that the technological scheme that its technical problem of solution is adopted is:
In the sliding cross coupling of being made up of two half-couplings and middle crosshead shoe, its each half-coupling all is made of two halfbodies, i.e. coupling upper semi-body and coupling lower semi-body.Coupling upper semi-body and coupling lower semi-body are fastened as one by threaded fastener, and the junction plane of the two is the plane by the shaft axis of half-coupling.Corresponding pin-and-hole is arranged on coupling upper semi-body and the lower semi-body, the locating stud location is arranged in the pin-and-hole.
The utility model is that the technological scheme that its technical problem of solution is adopted can also be:
The center line of the keyway on the coupling upper semi-body of sliding cross coupling and the junction plane of coupling lower semi-body and the half-coupling is vertical.Threaded fastener adopts high-strength bolt and nut.There is bolt boss at the Bolt Connection position of coupling upper semi-body and lower semi-body.
Each the coupling upper semi-body of sliding cross coupling and the high-strength bolt of coupling lower semi-body adopt four bolts, and locating stud adopts two, and they are symmetrically distributed in the both sides of coupling shaft axis.
The utility model compared with prior art its beneficial effect is:
1. not only can guarantee original performance of sliding cross coupling, and make its assembling and dismantle more convenient, the maintenance and accident treatment become easy and convenient.
2. simple in structure, be easy to processing.
Description of drawings
Fig. 1 is the structural representation plan view of the utility model sliding cross coupling
Fig. 2 is the structural representation side view of the utility model sliding cross coupling
Fig. 3 is the structural representation right side view of the utility model sliding cross coupling
Among the figure: junction plane, 10-bolt boss, the 11-right side half-coupling lower semi-body of lower semi-body on 1-left side half-coupling upper semi-body, the middle crosshead shoe of 2-, 3-high-strength bolt, 4-nut, 5-locating stud, 6-right side half-coupling upper semi-body, 7-left side half-coupling lower semi-body, 8-keyway, the 9-coupling.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1～3, the utility model sliding cross coupling is made up of two half-couplinves and middle crosshead shoe (2).Wherein each half-coupling all is made of two halfbodies, that is: the half-coupling in left side has coupling upper semi-body (1) and coupling lower semi-body (7) to constitute; The half-coupling on right side is made of coupling upper semi-body (6) and coupling lower semi-body (11).Coupling upper semi-body and lower semi-body be by threaded fastener high-strength bolt and nut (3,4), the fastening one that is connected into, and the junction plane of the two (9) is by the shaft axis of half-coupling, and vertical with the center line of keyway (8) on the half-coupling.Corresponding pin-and-hole is arranged on coupling upper semi-body and the coupling lower semi-body, have locating stud (5) to position in the pin-and-hole.Have on the coupling upper semi-body the keyway (8), coupling upper semi-body and lower semi-body are symmetrical up and down with its junction plane (9).
There is bolt boss (10) the shaft sleeve part both sides of coupling upper semi-body and lower semi-body, and bolt boss (10) has been located through hole, and left and right sides boss (10) respectively has two through holes and a taper hole, amount to four through holes and two taper holes.Four bolts (3) and two locating studs (5) are housed in the hole altogether.Bolt (3) adopts the high strength hexagon head bolt of 8.8 grades of mechanical propertys, and adds spring washer and plain washer, omits among the figure.Locating stud (5) adopts and opens the tail straight pin, with anti-loose.
In other words, the utility model is two half-couplings with the sliding cross coupling of routine, and to cut open be two halfbodies to symmetry vertically; For guaranteeing that two halfbodies do not misplace, locate, with bolt two halfbodies held tightly on transmission shaft, with the key on transmission shaft transmitting torque together with locating stud.So claim the split type coupling again.
In addition, the through hole at the bolt boss place, the left and right sides of lower semi-body also can adopt tapped hole, the fastening connection of assembling high-strength screw in the tapped hole.Perhaps, do not add bolt boss, and at the shaft sleeve part both sides of coupling upper semi-body and lower semi-body processing bolt concave station.
Processing: with the foundry goods of coupling upper semi-body and lower semi-body, dig junction plane earlier, after two halfbody amalgamations, process the taper hole of two locating studs, locate with locating stud.Then, the processing bolt hole connects with bolton.Again, with the axle center hole and the cylindrical of machined into half-coupling.
