Abstract
The utility model provides a vertical measuring pump safety coupling, by last shaft coupling, connect food tray, safe round pin, go up the guide, down guide, apron, down shaft coupling and drive screw forms, connect food tray fixed connection on last shaft coupling excircle step, lower shaft coupling inlays at last shaft coupling intracavity and can rotate relatively through the apron, upward guide, lower guide inlay respectively at last shaft coupling under, on the shaft coupling, safe round pin can be dismantled and insert in last guide on guide carry -over moment under and, go up the shaft coupling and pass through drive screw and reducer output axle carry -over moment, lower shaft coupling open have with transmission shaft complex positive limit shape hole. The utility model has the advantages of: installing and removing the convenience, changing the safe ten fens convenient and fast that sell, the shutdown maintenance time is short, exists under the oil leak circumstances at the reduction gear, and the food tray that connects from the area on the shaft coupling possesses the oil storage function, can effectively protect lower extreme equipment not contaminated under the circumstances that does not have discovery in time.
Description
Technical field
The utility model belongs to chemical fiber machinery fiber spinning art, is specifically related to a kind of vertical metering pump safety coupling of spinning machine.
Background technique
In fibre spinning production process; between retarder and spinning measuring pump drive shaft, coupling generally needs to have safe shearing function; under there are the abnormal conditions such as stuck in metering pump; coupling can cut off safety pin; interruption moment transmit, thus protection metering pump and retarder, motor etc. not damaged.At present, existing coupling has following shortcoming: one is that structure is comparatively complicated, and safety pin is changed and can need be carried out with special tool, and replacing construction is long.Two is adopt keyed jointing between coupling and retarder and transmission shaft more, and dismounting is quick not.Three are kinds of drive is vertical, and retarder exists leakage of oil situation sometimes because of a variety of causes, and coupling does not possess and connects functional oil, and when not having Timeliness coverage, lower end equipment is easily polluted in leakage of oil.
Summary of the invention
The purpose of this utility model is: for solving the problem, and provides a kind of vertical metering pump safety coupling.
The technical solution of the utility model: the utility model is made up of upper coupling, oil drip pan, safety pin, upper guide, lower guide, cover plate, lower coupler and drive screw, oil drip pan is fixedly connected on upper coupling cylindrical step, lower coupler is embedded in upper coupling chamber by cover plate and also can relatively rotates, upper guide, lower guide are embedded on upper coupling, lower coupler respectively, and safety pin detachable interposing is carry-over moment on upper guide and downside pin cover; Upper coupling is by drive screw and speed reducer output shaft carry-over moment, and lower coupler has the positive limit shape endoporus coordinated with transmission shaft.
Preferably, safety pin has groove at upper coupling and lower coupler end face joint, guarantees that the utility model better can cut off safety pin, interrupts moment transmission.
The utility model has the advantage of: mounting or dismounting are convenient; change safety pin fast very convenient, fault power time is short, deposits in case of leakage at retarder; the oil drip pan that coupling carries possesses oil storage function, when there is no Timeliness coverage can available protecting lower end equipment not contaminated.
Accompanying drawing explanation
Fig. 1: the utility model structural representation;
Fig. 2: the utility model A-A sectional view;
In figure: 1. speed reducer output shaft, 2. upper coupling, 3. oil drip pan, 4. safety pin, 5. back-up ring, 6. go up guide, 7. descend guide, 8. cover plate, 9. lower coupler, 10. transmission shaft, 11. drive screws.
Embodiment
As shown in Figure 1-2, upper coupling 2 top is processed with a mounting hole, pass speed reducer output shaft 1 by drive screw 11 and realize transmitting torque with locking nut locking, middle bench place is processed with step hole for installing guide 6, oil drip pan 3 is fixedly mounted on upper coupling 2 cylindrical step, upper coupling 2 lower end surface is along the circumferential direction processed with tapped hole for installing cover plate 8, and lower coupler 9 is embedded in upper coupling 2 chamber by cover plate 8 and also can relatively rotates; Lower coupler 9 upper-end surface is processed with step hole for installing lower guide 7, safety pin 4 is removably inserted in carry-over moment on upper guide 6 and lower guide 7 by back-up ring 5 location, safety pin 4 is processed with groove at upper coupling 2 and lower coupler 9 end face joint, cut off from groove during overload, a positive hexagon endoporus is machined in the middle of lower coupler 9, in transmission shaft 10 load hole, thus realize the transmission of coupling to torque transmission shaft.
