The utility model belongs to the field of transmission and overload protection application technology of transmission machines. The shaft coupling comprises a shaft coupling main body, a working machine half-shaft coupling, a motor half-shaft coupling and a middle section; the shaft coupling main body comprises an inner sleeve, an outer sleeve, a plurality of slide blocks and a bearing body; the bearing body is arranged between the inner sleeve and the outer sleeve; the outer sleeve is split away from and can slip on the work half-shaft coupling and is connected with a working main machine; a plurality of wedge grooves are uniformly distributed in a peripheral circle of the inner sleeve; the slide blocks are arranged in and match the grooves; and each of the slide blocks is of a wedge hollow structure, a wedge lead block is arranged in each of the slide blocks, and an arc-shaped anti-wearing rubber layer is arranged on each of the slide blocks. According to the utility model, in an overload eliminating process, there is no damage to any parts, there is no need to stop the unit to exchange and adjust the parts, and torque is transmitted via automatic slip automatic reset. The shaft coupling is characterized by simple and compact structure, and low manufacture and operating cost.
Description
Technical field
The utility model relates to a kind of Overloading protective coupling, relates in particular to a kind of slipping on overload coupling that automatically resets, and belongs to the transmission and the overload protection applied technical field that rotate unit.
Background technique
Traditional overload protection drive has the various ways such as shear pin formula, hydraulic type, friction-disc. and they have a common shortcoming; it is exactly torque overload in transmission; protecting component is destroyed; cause unit to stop; after the protecting component that need more renew, just can rework, its inefficiency has also increased the maintenance cost of equipment.
Summary of the invention
The utility model be take and addressed the above problem as object; mainly for traditional overload protection drive device; because torque overload protecting component is destroyed; cause unit to stop; the problems such as equipment operating cost increase of bringing; and providing a kind of under unit moment of torsion nominal situation, its effect is equivalent to a Daepori communications and liaison axial organ; When unit for a certain reason, as: during the super nominal situation of clamping stagnation moment of torsion, automatic slipping protection unit; When unit recovers normal, the novel slipping on overload of the normal delivery moment of torsion that automatically stops the skidding coupling that automatically resets.
For achieving the above object, the utility model adopts following technical proposals: the slipping on overload coupling that automatically resets, comprises coupling main body, working machine half-coupling (6), motor half-coupling (7) and middle node (8).Above-mentioned coupling main body, comprises inner sleeve (1), overcoat (2), some slide blocks (3) and bearing support (4), and bearing support (4) is located between inner sleeve (1) and overcoat (2).Inner sleeve (1) is connected with unit motor, and overcoat (2) adopts and working machine half-coupling (6) split, slip structure, is connected with working host.
Above-mentioned working machine half-coupling (6) is connected with coupling main body by bolt, and coupling main body one side is provided with baffle plate (10); Above-mentioned motor half-coupling (7) is connected with a side of middle node (8) by bolt, and the opposite side of middle node (8) is connected with inner sleeve (1) by bolt.The outer border of above-mentioned inner sleeve (1) has some uniform wedge slots (9), is provided with slide block (3) and matches in wedge slot (9).
Above-mentioned slide block (3) is wedge shape and hollow, and wedge shape lead is equipped with in the inside, and is provided with arc abrasive rubber layer (5), and its outer curvature radius is identical with overcoat (2);
Above-mentioned wedge slot (9) is at least provided with 8.
In overload generation, exclusion process, the utility model coupling, without any damage parts, does not need compressor emergency shutdown to change yet and adjusts part, is the transmitting torque that automatically resets that automatically skids completely.
Feature of the present utility model and beneficial effect:
The utility model is compared with existing various forms overload protection drive product, and structure is more simple compact, low cost of manufacture.Its slide block is more much bigger than moment of torsion with the friction torque of outer inner room, non-slip without wearing and tearing; When unit blocks, slide block centrifugal force moment reduces to zero, with overcoat without friction, therefore the life-span is long.While using this clutch unit to block, needn't change or adjust clutch component, saving processing time unit efficiency is high.In overload generation, exclusion process, the utility model coupling, without any damage parts, is the transmitting torque that automatically resets that automatically skids completely, and operating cost is cheap.

Embodiment
Embodiment
With reference to Fig. 1-4, the slipping on overload coupling that automatically resets, comprises coupling main body, working machine half-coupling 6, motor half-coupling 7 and middle node 8.Above-mentioned coupling main body, comprises inner sleeve 1, overcoat 2, some slide blocks 3 and bearing support 4, and bearing support 4 is located between inner sleeve 1 and overcoat 2.Inner sleeve 1 is connected with unit motor, and overcoat 2 adopts and 6 splits of working machine half-coupling, slip structure, is connected with working host.
Above-mentioned working machine half-coupling 6 is connected with coupling main body by bolt, and coupling main body one side is provided with baffle plate 10; Above-mentioned motor half-coupling 7 is connected with a side of middle node 8 by bolt, and the opposite side of middle node 8 is connected with inner sleeve 1 by bolt.The outer border of above-mentioned inner sleeve 1 has some uniform wedge slots 9, is provided with slide block 3 and matches in wedge slot 9.
Above-mentioned slide block 3 is wedge shape hollow-core construction, and wedge shape lead is equipped with in the inside, and periphery is provided with arc abrasive rubber layer 5, and its outer arc radius of curvature is identical with overcoat 2;
Above-mentioned wedge slot 9 is at least provided with 8, slide block 3 of the interior placement of an one wedge slot 9.
During work, inner sleeve 1 is rotated with motor, and slide block 3 is thrown away by centrifugal action from wedge slot 9, is pressed on overcoat 2 inner rings, and frictionally drives overcoat 2 and working machine acting.When working machine blocks because of certain reason, centrifugal force moment drops to zero, and frictional force also drops to zero, and slide block 3 departs from and skids with overcoat 2, protection motor.After Failure elimination, motor is able to continuous turning block 3 and presses down on overcoat 2 inner rings at centrifugal action, and frictionally continues to drive overcoat 2 and working machine acting.
