Abstract
The utility model discloses a universal joint for an isolating switch transmission device, and is used for solving the problem that a universal joint is easy to be loosened after being used for a long time. The universal joint comprises a driven universal joint fork, a crossed joint head and a driving universal joint fork, wherein the driven universal joint fork and the driving universal joint fork are respectively articulated with the crossed joint head through two mutually vertical pin shafts. After improvement: the handle end part of the driven universal joint fork is provided with a positioning pin shaft hole which is a through hole and passes through the handle end of the driven universal joint fork radially. According to the utility model, the structures of a transmission shaft and the driven universal joint fork are simplified, thus the mounting is simpler, more convenient and reliable, and the problem of looseness after long-time use is solved; and additionally, the handle end of the driving universal joint fork is provided with a radial through hole, thus the handle end of the driving universal joint fork can be directly connected with a hot galvanized pipe through a connecting pin shaft, and the field assembly operation is simplified.
Description
Technical field
The utility model relates to a kind of electric component, especially for the universal joint of isolating switch transmission device, belongs to basic electrical equipment technical field.
Background technique
Universal joint is a universal joint, is the parts of realizing the varied angle transmission of power, is used for the position that needs change the transmission axial direction, and it can make the angle between the connected part change within the specific limits.When carrying out the installation exercise of isolating switch at the scene; Can there be some deviations in position and the former drawing design of operating device on basic erection column; For satisfy transmission of power, adapt to turn to the operating device installation process in the axial direction angle that produced change, universal joint assembling commonly used is connected between isolating switch transmission shaft and the actuating linkege.The common universal joint that is used for the connection of isolating switch transmission shaft; Its formation comprises driven universal-joint fork, cross section header, active universal-joint fork, and structure is as shown in Figure 2, wherein; Driven universal-joint fork 1 pommel is tubulose and is provided with keyway 6 that the keyway respective side is provided with bolt hole; Initiatively the universal-joint fork pommel is the entity cylinder.The problem that this Cardan joint exists is following: 1. driven universal-joint fork is provided with keyway; Also to process keyway on the corresponding transmission shaft; Increase the preparation process of transmission shaft, and it is circumferentially spacing to need the interpolation flat key to do, the keyway respective side is done axial restraint with bolt; The long-term use easily comes off the effect of the transmission that runs out of steam because of the insecure universal joint that makes that is threaded; 2. initiatively universal joint 3 fork handle ends are cylindrical structure, need punching could be connected use with actuating linkege at the scene in the installation process, increase the assembled in situ work difficulty.
The model utility content
The utility model is used to overcome the defective of prior art and a kind of universal joint of being convenient to process and assemble that is used for the isolating switch transmission device is provided.
The alleged problem of the utility model is that following technological scheme solves:
A kind of universal joint that is used for the isolating switch transmission device; Comprise driven universal-joint fork, cross section header and active universal-joint fork in the formation; Driven universal-joint fork, initiatively universal-joint fork is hinged through two orthogonal bearing pins and cross section header respectively; Its specialization is: said driven universal-joint fork pommel place is provided with the locating stud axis hole, and the locating stud axis hole is a through hole, and it radially passes driven universal-joint fork pommel.
The above-mentioned universal joint that is used for the isolating switch transmission device, said active universal-joint fork pommel is provided with the connecting pin axis hole, and the connecting pin axis hole is a through hole, and it radially passes initiatively universal-joint fork pommel.
The utility model improves processing problem complicated and that long-term use is prone to get loose to common isolating switch transmission device with universal joint and rotatingshaft Placement; Abandon the keyway on the driven universal-joint fork; Be improved to radial direction through hole type design, make original spacingly and change into directly with the form of bolt and to fix, simplified the manufacture difficulty of transmission shaft and driven universal-joint fork with alignment pin with flat key; Make installation easier, reliable, solve the long-term problem that gets loose of using; In addition, radial direction through hole is set, makes it can directly pass through to connect bearing pin and be connected, or be connected use with hot dip galvanizing pipe after adding armful folder, simplify the assembled in situ operation with hot dip galvanizing pipe at active universal-joint fork pommel.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the gimbal structure schematic representation before improving;
Fig. 3 is the schematic representation of the utility model when being used for isolating switch.
The label of each parts is represented as follows in the accompanying drawing: 1. driven universal-joint fork; 2. cross section header; 3. initiatively universal-joint fork, 4. locating stud axis hole, 5. connecting pin axis hole, 6. keyway, 7. hot dip galvanizing pipe, 8. armful folder; 9. universal joint, 10. transmission shaft.
Embodiment
Referring to Fig. 1; The utility model constitutes and to comprise driven universal-joint fork 1, cross section header 2 and universal-joint fork 3 initiatively; Driven universal-joint fork, initiatively universal-joint fork is hinged through two orthogonal bearing pins and cross section header respectively, and universal joint shaft all can use in 0 ° of-47 ° of scope to the drift angle.The utility model is the improvement of driven universal-joint fork: keyway is not set; Pommel place at driven universal-joint fork 1 is provided with locating stud axis hole 4, and the locating stud axis hole is a through hole, and it radially passes driven universal-joint fork pommel; Also process pin shaft hole during use on the connected transmission shaft; Alignment pin is radially passed driven universal-joint fork pommel and transmission shaft, play axial, circumferential positioning action simultaneously, and positioning stablity is reliable.
Still referring to Fig. 1, it is at active universal joint 1 fork handle end connecting pin axis hole 5 to be set that another place of the utility model improves, and the connecting pin axis hole is a through hole, and it radially passes initiatively universal-joint fork pommel.After this hole was set, need not punch in the field-mounted process with hot dip galvanizing pipe or to embrace to press from both sides was connected use, has reduced the assembled in situ work difficulty.
Referring to Fig. 3, when the utility model was used for the isolating switch transmission device, the driven universal-joint fork 1 of universal joint 9 was connected with transmission shaft 10, and initiatively universal-joint fork 3 connects hot dip galvanizing pipe 7 (actuating linkege) through embracing folder 8.When operating device drove the hot dip galvanizing pipe rotation, transmission shaft was also done spinning movement through the power transmission of universal joint, and universal joint plays the effect of connection, transmission, and the cross section header of universal joint also can be accomplished powerdriven effect when axially augular offset being arranged.
