Abstract
The utility model discloses a ring piston type pneumatic clutch with large transference torque and relatively low engaging and disengaging frequency, which is suitable for pressing machines, diggers, etc. The ring piston type pneumatic clutch is characterized in that an air path bulkhead (12) which is fixed by a bolt (11) is arranged in the stepped hole of a shaft sleeve base (1), the air path bulkhead is provided with an air drain (14), and both ends of an air pipe assembly (10) are respectively communicated with the air drain (14) and an air chamber arranged between an air cylinder (8) and a piston (6). The air path structure decreases the axial dimension of the clutch, so the ring piston type pneumatic clutch has the advantages of convenient installation, stable engaging and disengaging ability, and long service life.
Description
The utility model relates to a kind of pneumatic clutch, and is big especially for transmitting torques such as press machine, excavator, drilling rigs, the pneumatic clutch of the big machinery that the clutch frequency is lower.
Pneumatic clutch is a mechanism mechanically commonly used, can be divided into piston type, diaphragm type and pneumatic tyre formula three major types by the air cylinder structure form, wherein the piston type pneumatic dynamic clutch can be made 2-6 friction surface according to the moment of torsion needs, so the transmitting torque maximum is particularly useful for big machinery.Present piston type pneumatic dynamic clutch all is a whole garden piston cylinder structure, this traditional piston type pneumatic dynamic clutch mainly contains following shortcoming: 1, as shown in Figure 2, because cylinder and piston all are contained on the end face of the belt wheel outside, connect to one with belt wheel, so axial dimension is big, weight is heavier.When 2, clutch is connected with main frame, must dismantle cylinder, piston etc., complexity is installed, assembly precision is difficult to guarantee.
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, designs a kind of in light weightly, and axial dimension is little, and compact structure is easy for installation, the pneumatic clutch of long service life.
Major character of the present utility model is the gas circuit structure that has changed prior art, and design has a gas circuit that offers air flue (14) silently (12), and it is fixed by bolts in the step hole of sleeve block (1).One end of tracheae assembly (10) communicates with air flue (14), and the other end communicates with air chamber between cylinder (8) and the piston (6), thereby has reduced the axial dimension of clutch, makes structure more gather and be convenient to and installs.
Accompanying drawing 1 is a structural drawing of the present utility model.
Accompanying drawing 2 is the structural drawing of prior art.
Be further described below in conjunction with 1 pair of concrete structure of the present utility model of accompanying drawing and working principle.
Ring gear of annular piston pneumatic clutch (2) and outer gland (9) are separately fixed at the two ends of belt wheel (3), the external diameter of outside friction disc (4) and ring gear (2) connect with the moving connection of joining of involute splines tooth, the internal diameter of interior friction plate (5) also connects with moving joining of involute splines tooth with sleeve block (1), above-mentioned three can move axially each other, but can not rotate, Returnning spring (13) is contained in the sleeve block (1), and sleeve block (1) cooperates with flat key with output (input) axle (16).
Gas circuit silently (12) is fixed in the step hole of sleeve block (1) with bolt (11).Cylinder (8) is threaded with bearing support (1), and piston (6) is positioned at cylinder (8), and the two constitutes an air chamber with seal ring (7) sealing.Gas circuit silently offers air flue (14) on (12).One end of tracheae assembly (10) communicates with air flue (14), and the other end communicates with air chamber between cylinder (8) and the piston (6).
Pressurized air (source of the gas) is from the gas circuit air flue of (12) (14) silently, enters air chamber between cylinder (8) and the piston (6) through tracheae assembly (10).Promote piston (6), interior friction plate (5), outside friction disc (4) be the end face of compression axis block set (1) respectively.Sleeve block (1) and belt wheel (3) run-in synchronism, machine power output is when pressurized air is discharged.Under the elastic force effect of Returnning spring (13), friction plate (5) in promoting, piston (6) moves to right, and inside and outside friction plate is disconnected from each other, and friction torque disappears, and the output machine power stops.In above-mentioned working procedure, owing to not producing, cylinder (8) do not rotatablely move, so seal ring (7) is not easy to wear.
Pneumatic clutch compact conformation of the present utility model, compare with the traditional, pneumatic clutch of equal-wattage, axial dimension can dwindle 1/4 approximately, and weight alleviates 1/5 approximately. When the utility model is installed on the power shaft, only need fixedly gas circuit bolt silently of dismounting, need not to dismantle other in addition parts, install very convenient, the assembly precision height, and have clutch steady, and the advantage of long service life, it is particularly useful for the big-and-middle-sized machineries such as large pressing machine, excavator, oil drilling machine, Ship Power Equipment.
