Detailed description of the invention
Torque-limiting type low-speed brake of the present invention, its preferably detailed description of the invention as shown in Figure 1, Figure 2, Figure 3 shows, torque-limiting type low-speed brake comprises initiatively hub 1, pressing plate 2, right support dish 3, movable friction plate group 4, static friction sheet group 5, driven hub 6, dish spring 7, dish spring briquetting 8, adjusting screw(rod) 9, roller 10, roller cover 11, foreign steamer 12, left support dish 13, stay bearing plate 14 and oil sealing dish 15.
Initiatively hub 1 is bolted with pressing plate 2, movable friction plate group 4 is the external tooth setting-in with active hub 1 by internal tooth, static friction sheet group 5 is by the internal tooth setting-in of external tooth and driven hub 6, and driven hub 6 is bolted with right support dish 3, and driven hub 6 is bolted with left support dish 13.
Right support dish 3 is provided with tapped bore, and adjusting screw(rod) 9 is threaded connection with right support dish 3, and adjusting screw(rod) 9 is located at dish spring briquetting 8 right sides, and dish spring briquetting 8 is located at dish spring 7 right sides, and dish spring 7 is located at static friction sheet group 5 right sides.
Roller 10 is located between driven hub 6 and foreign steamer 12, and the axle of roller 10 is located in roller cover 11, between roller cover 11, is bolted, and stay bearing plate 14 is bolted with foreign steamer 12, and stay bearing plate 14 is bolted with oil sealing dish 15.
Torque-limiting type low-speed brake of the present invention has following inventive point:
Torque-limiting type low-speed brake is provided with adjusting screw(rod), can be according to actual conditions regulation disc spring stroke, and the wearing and tearing between compensation movable friction plate group and static friction sheet group, make the check torque keeping of holdback in setting range;
Torque-limiting type low-speed brake carrys out transmitting torque by the friction force between movable friction plate group and static friction sheet group, can actv. the highest moment of torsion of restriction torque-limiting type low-speed brake, improved safety factor.
Below in conjunction with accompanying drawing, the principle of work of torque-limiting type low-speed brake is further illustrated:
