Abstract
The utility model discloses a speed limit safety friction clutch for in mechanical & electrical transmission, including input shaft, front end housing, bearing, clutch housing, initiative level clutch blocks, initiative level reset spring, driven level clutch blocks, driven level reset spring, rear end cap that has the keyway and the output shaft that has the keyway. The input shaft passes through the bearing and is supporting clutch housing, and the rear end cap passes through bolted connection with clutch housing, and the output shaft passes through bolted connection with the rear end cap, and the clutch passes through the output shaft and links to each other with the working machine. Initiative level clutch blocks is evenly fixed on clutch housing through the bolt of wearing initiative level reset spring, and driven level clutch blocks is evenly fixed on the input shaft through the bolt of wearing driven level reset spring. The utility model discloses simple structure, maintenance convenience can realize soft start and speed limit safety protection.
Description
Technical field
The utility model relates to friction clutch technical field, particularly a kind of for the speed-limiting safety friction clutch in Mechanical & Electrical Transmission.
Background technique
Inevitably use electromechanical transmission mechanism in industrial production, clutch is one of parts important in Mechanical & Electrical Transmission, and the produced friction clutch of application tribology principle serves good soft start effect.But the friction clutch used at present, complex structure, maintenance are inconvenient, when exceeding the predetermined rotating speed of machinery, effectively can not carry out speed-limiting protection, easily damage some component of machinery, even bring potential safety hazard to device operator.
Summary of the invention
Inconvenient and can not the problem of speed-limiting protection in order to overcome existing friction clutch complex structure, maintenance; the purpose of this utility model is to provide a kind of for the speed-limiting safety friction clutch in Mechanical & Electrical Transmission; have structure simple, overhaul feature easily; can soft start function be realized, when exceeding predetermined speed, safety protection can be carried out by automatic speed-limiting again.
The technological scheme that the utility model adopts is: a kind of for the speed-limiting safety friction clutch in Mechanical & Electrical Transmission, comprise with the input shaft of keyway, front cover, bearing, clutch housing, initiatively level brake pad, initiatively level Returnning spring, driven level brake pad, driven level Returnning spring, rear end cover and the output shaft with keyway, input shaft clutch housing by bearings, rear end cover and clutch housing are bolted, output shaft and rear end cover are bolted, and clutch is connected with working machine by output shaft.Initiatively level brake pad is evenly fixed on clutch housing by the bolt being installed with initiatively level Returnning spring, and brake pad is fixed with friction plate, and brake pad is close on input shaft under spring force with one end of friction plate; Driven level brake pad is bolted on input shaft by what be installed with driven level Returnning spring, and brake pad keeps certain distance with one end of friction plate and clutch housing.
The utility model has following Advantageous Effects: the utility model structure is simple, maintenance is convenient, when Mechanical & Electrical Transmission, can realize soft start function, can carry out safety protection by automatic speed-limiting again when exceeding predetermined speed.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Fig. 2 is the A-A sectional view that in Fig. 1 mode, driven level brake pad connects input shaft.
Fig. 3 is that in Fig. 1 mode, initiatively level brake pad connects the B-B sectional view of clutch housing.
In figure, 1-with the input shaft of keyway, 2-front cover, 3-bearing, 4-clutch housing, 5-driven level friction plate, 6-driven level Returnning spring, 7-driven level brake pad, 8-initiatively level friction plate, 9-initiatively level brake pad, 10-initiatively level Returnning spring, 11-rear end cover, 12-with the output shaft of keyway.
Embodiment
Composition graphs 1, for the speed-limiting safety friction clutch in Mechanical & Electrical Transmission, comprise with the input shaft 1 of keyway, front cover 2, bearing 3, clutch housing 4, driven level friction plate 5, driven level Returnning spring 6, driven level brake pad 7, initiatively level friction plate 8, initiatively level brake pad 9, initiatively level Returnning spring 10, rear end cover 11 and the output shaft 12 with keyway.Input shaft clutch housing by bearings, initiatively level brake pad is evenly fixed on clutch housing by the bolt being installed with initiatively level Returnning spring, driven level brake pad is evenly fixed on input shaft by the bolt being installed with driven level Returnning spring, rear end cover and clutch housing are bolted, and output shaft and rear end cover are bolted.
Composition graphs 2 and Fig. 3, the utility model driven level brake pad is bolted on input shaft by what be installed with driven level Returnning spring, certain distance is kept with clutch housing, initiatively level brake pad is bolted on clutch housing by what be installed with initiatively level Returnning spring, and the one end with friction plate is close on input shaft under the elastic force effect of less active level Returnning spring.
Its working principle is: during electric motor starting, speed-limiting safety friction clutch input shaft is owing to contacting with the friction plate on active level brake pad, just start the phenomenon that there will be friction slip, the elastic force that driven level brake pad overcomes spring when the rotating speed of motor reaches certain limit starts outer moving, by centrifugal action, friction plate is compressed gradually with clutch housing, rely on frictional force transmitting torque, drive clutch housing rotates, under the acting in conjunction of the friction torque produced at active level brake pad and driven level brake pad, output shaft starts to run well, thus realize soft start.Motor continues to accelerate; when input shaft rotating speed exceedes desired speed; initiatively level brake pad will under centrifugal force be greater than spring-force driven dual; automatically disengage with the contact of input shaft and not transmitting torque; driven level brake pad because working machine load is large and little and occur the phenomenon of friction slip with inner walls area of contact, can realize speed-limiting protection.
The technology contents do not addressed in aforesaid way is taked or uses for reference prior art to realize.
