(4) description of drawings:
Fig. 1 cuts air pressure friction clutch-brake structural representation for oil of the present utility model;
(5) embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, oil is cut the air pressure friction clutch-brake and is comprised output shaft 1, brake strip 2, intermediate piston 3, clutch friction plate 4, Returnning spring 5, inlet hole 6, input shaft 7, middle housing 8, spline housing 9, input end casing 10 and output terminal casing 12, middle housing 8, input end casing 10 and output terminal casing 12 are formed confined space, middle housing 8 is provided with inlet hole 6, input shaft 7 passes input end casing 10, input shaft 7 one ends are outside input end casing 10, one end is in input end casing 10, the end of input shaft 7 in input end casing 10 is equipped with clutch friction plate 4, clutch friction plate 4 is installed between input end casing 10 and the spline housing 9, brake strip 2 is installed between intermediate piston 3 and the output terminal casing 12, output shaft 1 passes output terminal casing 12, output shaft 1 (splined shaft) end is outside output terminal casing 12, one end is in output terminal casing 12, the end of output shaft 1 in output terminal casing 12 is equipped with brake strip 2, brake strip 2 is connected with the bearing cap of output terminal casing 12, between brake strip 2 and clutch friction plate 4, be provided with intermediate piston 3, be with spline housing 9 in the intermediate piston 3, output shaft 1 is in spline housing 9 inside, Returnning spring 5 one ends are fixed on the input end casing 10, Returnning spring 5 the other ends are connected with intermediate piston 3, intermediate piston 3 is under the effect of pressurized air and Returnning spring 5, utilize pressurized air and Returnning spring 5 to promote intermediate piston 3 and compress brake strip 2 and clutch friction plate 4, realize main driven shaft transmitting torque on coaxial line, it is had engage or separation function.Brake strip 2 and clutch friction plate 4 are made up of carbon friction dish of alternately installing and the friction disk that adheres to high-quality friction material, and oily control flume casts on the friction disk.Internal spline is arranged, with spline fitted realization clutch and the braking function on the output shaft 1 on the friction disk.During clutch, friction disk is fixed on the bearing pin of input shaft 7, and during braking, friction disk is fixed on the bearing pin of housing.The splined section of output shaft 1 comprises the Rational flow that receded disk impeller is used for keeping oil between friction disk and the friction plate.Braking is by pressure control, and after clutch discharged, braking can be automatically by Returnning spring 5 pressurized operations.The relative movement that brake strip 2 and clutch friction plate are 4 is protected by oil film, and is lubricated splendid with cooling effect.
During action, pressurized air feeds from middle casing top suction port, and piston motion promotes spline housing and moves to input end along splined shaft, compresses clutch friction plate, clutches engaged, and this moment, brake strip separated, and the spline output shaft rotates with input shaft.Because the carbon steel drive plate links to each other with input shaft with pin, friction disk links to each other with output shaft with spline, and this has just guaranteed that two axles rotate with identical speed.When disconnecting source of the gas (external electromagnetic valve), piston to the output terminal motion, compresses brake strip under the effect of brake spring, and this moment, clutch friction plate separated, and realized the braking of output shaft.Specified braking force is provided by brake spring.If desired, can provide bigger braking force by heavy-duty spring.
Oil is cut under the air pressure friction clutch-brake normal condition and is in application position, can not rotate when output shaft is in application position.
