On the basis of the technical scheme, the following further technical scheme is also available:
the compaction table is provided with a boss which is correspondingly matched with the arc-shaped elastic sheet.
A group of sinking tables which are correspondingly matched with the fixed anti-drop device are uniformly distributed on the connecting plate.
The convex block is in an inward convex arc shape, the length of the convex block is the same as the height of the groove wall, and the axis of the convex block is perpendicular to the plane of the groove bottom.
The invention has the advantages that:
the invention has simple structure, convenient manufacture and low cost, and when the torque of the driver exceeds the set value, the arc-shaped elastic sheet deforms and is separated from the fixed anti-separation device, so that the compressor stops working, thereby playing the role of overload protection.
Description of the drawings:
FIG. 1 is a schematic diagram of the structure of the present invention;
FIG. 2 is a schematic diagram of an exploded construction of the present invention;
fig. 3 is a schematic perspective view of the present invention.
The specific embodiment is as follows:
as shown in fig. 1-3, a buckle type torque limiter comprises a circular connecting plate 1, a connecting head 1e protruding out of the connecting plate body at the center of the connecting plate 1, shaft holes 1b coaxially distributed on the connecting head 1e, and a coupler 1c coaxially distributed in the shaft holes 1 b. A group of mounting tables 1d extend outwards from the outer circular surface of the connecting plate 1, three mounting tables 1d are uniformly distributed on the outer side of the outer circular surface of the connecting plate 1, a sinking table 1a is arranged on the mounting table 1b, the sinking table 1a is groove-shaped, and a notch 1f communicated with the thickness end surface of the mounting table 1d is arranged along the radial direction of the connecting plate 1.
The sinking tables 1a of each mounting table 1b are connected with a fixed anti-drop device 2 through first rivets 5, the fixed anti-drop devices 2 are in a through groove shape, and an arc-shaped transition section is arranged between the groove bottom and the groove wall. A convex block 2a is arranged on the inner side of each groove wall 2b, the top end of the convex block 2a is connected with the top end of the groove wall 2b, the section of the convex block 2a is in a circular arc shape protruding towards the inner side of the groove wall, the whole convex block 2a is in a semi-cylindrical shape, the length of the convex block 2a is identical to the height of the groove wall, and the axis of the convex block 2a is perpendicular to the plane of the groove bottom. The fixed anti-drop device 2 and the upper protruding block 2a are of an integrated structure.
A fixed compression plate 4 which is coaxially matched with one side of the connecting plate 1 is arranged at the center of the fixed compression plate 4, a yielding hole 4c which is correspondingly matched with the connector 1e is arranged at the center of the fixed compression plate 4, a group of compression tables 4a are also arranged on the fixed compression plate 4, the compression tables 4a are corresponding to the mounting tables 1b on the connecting plate 1, and a boss 4b which is corresponding to the through groove of the fixed anti-drop device 2 is also arranged on each compression table 4 a. The fixed compression plate 4 is fixedly connected with the connecting plate 1 through a group of second rivets 6.
A coaxially matched reed 3 is arranged on one side of the fixed pressing plate 4, the fixed pressing plate comprises an annular main body 3c, and a group of yielding notches 3d corresponding to the second rivets 6 are uniformly distributed on the annular main body 3 c. Arc shrapnel 3a are uniformly distributed on the outer side of the annular main body 3a, a certain distance is reserved between the inner cambered surface of the arc shrapnel 3a and the outer circular surface of the annular main body 3c, and the circle center of the arc shrapnel 3a and the annular main body 3c are at the same point.
One end of the arc-shaped elastic sheet 3a is provided with a connecting hole 3b which is connected with the belt wheel, one side of the connecting hole is provided with an extension part which is connected with the annular main body 3c, and the joint of the extension part and the annular main body 3c is provided with an arc-shaped groove 3e, so that stress concentration is effectively avoided. The inner cambered surface and the outer cambered surface of the end part of the other end of the arc-shaped elastic sheet 3a are respectively provided with an arc groove 3f which is correspondingly matched with the convex block 2a on the fixed anti-drop device 2.
The assembly process comprises the following steps:
the fixing anti-drop device is fixed to the sinking table of the mounting table through the first rivet, the fixing pressing plate is placed on one side of the connector, the boss is adjusted to be above the through groove of the corresponding anti-drop device, and the end part of the other end of the arc-shaped elastic piece is inserted into the through groove of the fixing anti-drop device, so that the protruding block on the fixing anti-drop device is clamped with the arc-shaped groove on the arc-shaped elastic piece. Finally, the connecting plate and the fixed pressing plate are connected together through a second rivet. The lower surface of the end part of the other end of the arc-shaped elastic sheet is contacted with the groove bottom of the fixed anti-drop device, the upper surface of the end part of the other end of the arc-shaped elastic sheet is pressed by the boss, and the condition that the arc-shaped elastic sheet moves up and down along the axis of the connector in the fixed anti-drop device during the operation of the device is effectively avoided through the up-down action of the groove bottom and the boss.
Working principle:
after the driver torque exceeds the set value, the end part of the arc-shaped elastic piece is deformed, the protruding block on the fixed anti-drop device cannot form limit fit with the arc-shaped groove on the arc-shaped elastic piece, so that the end part of the other end of the arc-shaped elastic piece is dropped out from the through groove of the fixed anti-drop device, the power of the belt pulley cannot be transmitted to the connecting head through the reed, the main shaft of the air-conditioning compressor is caused to lose power, and further the air-conditioning compressor is effectively protected.
Because this device can not take place the cracked condition of shell fragment when providing overload protection, consequently, just also can not take place to throw away because of the shell fragment fracture throws away, damage other parts's problem, the effectual maintenance cost of having reduced and other parts's life.
