Description
Technical field
The utility model relates to a kind of clutch, break and transmission system, is widely used in various machinery transmission systems, as metal forming machinery, metallurgical machinery, ship equipment etc., realizes the transmission of driving torque and the rapid braking of driven member.
Background technique
For some machinery, adopt the operation of clutch and break controlled motion mechanism and stop.When the needs motion moves, clutch; When the needs motion stops rapidly, the throw-out-of clutch brake engages.
Known pneumatic split type friction disk clutch and break adopt modular construction at present, see Fig. 1, and the left side is a clutch, and the right side is a break.
Clutch cylinder cap 103, piston 106 and clutch seat 1 01 assembling backs are connected with input shaft 112 by link 102, and clutch friction plate group 108 is connected with guide pin bushing 109, and guide pin bushing 109 is fixed on the driving wheel 111 by bolt 110.Cylinder cap 103, piston 106, inner seal ring 104 and exterior seal ring 107 form the air cavity of a sealing, entering air cavity from the pressurized air of outside promotes piston 106 and overcomes Returnning spring 105 resistances and move right, piston 106 and clutch seat 101 are pushed down friction plate group 108, and driving wheel 111 drives input shaft 112 by guide pin bushing 109, friction plate group 108, clutch seat 101, link 102 etc. and rotates.When pressurized air was discharged air cavity, Returnning spring 105 promoted piston 106 and is moved to the left, and piston 106 and clutch seat 101 are just thrown off with friction plate group 108.
Break cylinder cap 121, piston 118 and Brake Block 122 assembling backs are connected with input shaft 112 by link 102, and brake bush group 116 is connected with guide pin bushing 115, and guide pin bushing 115 is fixed on the frame 113 by bolt 114.Cylinder cap 121, piston 118, inner seal ring 120 and exterior seal ring 117 form the air cavity of a sealing, the clutch front brake must be thrown off earlier, enter air cavity from the pressurized air of outside and promote piston 118 and overcome brake spring 119 resistances and move right, piston 118 and cylinder cap 121 are thrown off with friction plate group 116.When pressurized air is discharged air cavity, brake spring 119 promotes piston 118 and is moved to the left, and piston 118 and cylinder cap 121 are pushed down friction plate group 116, because the effect of frictional force, the rotation of input shaft 112 just disappears on the frame 113 by Brake Block 122, friction plate group 116, guide pin bushing 115, realizes braking.The brake engages front clutch must be thrown off earlier.
Because clutch cylinder cap 103, piston 106 and clutch seat 101 builtup membeies and break cylinder cap 121, piston 118 and the whole inertia of Brake Block 122 builtup membeies all bear on the motion input shaft 112, become secondary part inertia, and the size of driven member inertia has determined the length of clutch time and brake time, big more clutch time of driven member inertia and brake time are long more, otherwise then short more.So under the operating conditions of clutch and the frequent bond-off of break, clutch and break are very easy to heating, working life is short.
Described pneumatic split type friction disk clutch of Fig. 1 and break are made up of one group of clutch friction plate group 108 and one group of brake strip group 116.When bigger clutch moment of torsion of needs and brake moment of torsion, can only realize by the external diameter that strengthens clutch and braking body.Because the inertia of part is directly proportional with the biquadratic of external diameter, therefore realization clutch and break more in the high pulling torque increase of driven member inertia bigger.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
As shown in Figure 2, the left side is a clutch among the figure, and the right is a break.
Clutch base 6 is connected on the follower input shaft, thrust disc 5 is supported on the clutch base 6, connect by spline, clutch base 6 moves axially relatively, and friction plate group 4 is supported on the gear ring 12, connects by spline, ring gear 12 moves axially relatively, piston 3 is installed in the cylinder 11, by inner seal ring 7 and exterior seal ring 8 sealings, forms an air cavity; Cylinder body 11 and ring gear 12 are fixed on the clutch driving wheel 13 by bolt 10, friction plate group 4 is connected with force transmiting disk 2 by guide finger 9, Returnning spring 1 is installed in cylinder body 11 counterbores and gives force transmiting disk 2 active force left, hold friction plates 4 by guide finger 9, so friction plate 4 is in disengaged condition during with thrust disc 5 natures.When the pressurized air from the outside enters air cavity from suction port, piston 3 promotes friction plates 4 and moves right, and friction plate 4 and thrust disc 5 engage, and rotates from the input shaft that drives motion by clutch that rotatablely moves of driving wheel 13.
From the above, only there are the clutch base 6 of clutch part and the break seat 21 and the thrust disc 22 of thrust disc 5 and brake portion to be connected on the input shaft of follower, and the remaining part that the remaining part in the clutch is connected on the driving wheel and in the break is connected on the frame 14, so the inertia of motion significantly reduces.
The friction plate group is a discoid part, and its interior week is the profile of tooth internal spline, and clutch base and break seat periphery are the profile of tooth external spliness, and internal spline cooperates with external splines and is used for transmitting torque.The still many group friction plates of no matter one group all are supported on clutch base or the break seat, are axially floating.There is no interconnected relationship between the friction plate, when external force (as pressurized air thrust or spring force) compressed friction plate and thrust disc, friction plate and thrust disc produced frictional force and transmitting torque.Two groups of clutch friction plate groups 4 and thrust disc 5 and two groups of brake bush groups 23 and the thrust disc 22 of having disposed shown in Figure 3 compared clutch torque with Fig. 2 and braking is original twice; Three groups of clutch friction plate groups 4 and thrust disc 5 and three groups of brake bush groups 23 and the thrust disc 22 of having disposed shown in Figure 4 compared clutch torque and braking and is original three times with Fig. 2.Compare with Fig. 2, among Fig. 3 and Fig. 4, the thickness of clutch base 6 and ring gear 12 and break seat 21 and ring gear 15 increases with friction plate group and thrust disc quantity, and what influence follower inertia only is clutch base 6, break seat 21 and clutch thrust disc 5 and retrothrust dish 22.Therefore compare with increase clutch and the increase of break diameter realization moment of torsion, the utility model realization moment of torsion increases gives motion inertia value added very little simultaneously.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiments, and needn't pass through performing creative labour being applied among other embodiments in the General Principle of this explanation.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
