Abstract
The invention relates to a swinging type overrunning clutch, which mainly solves the technical problem of clutch failure of the existing wedge-block type overrunning clutch caused by easy adhesion due to friction overheating. The swinging type overrunning clutch comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is connected with a machine unit auxiliary motor, the outer sleeve is connected with a main machine, and the swinging type overrunning clutch also comprises swinging blocks, control spring bodies and bearing bodies. The control spring bodies are arranged between the front part of the swinging block and the outer sleeve, and push the front edges of the swinging blocks to be projected out of the inner ring of the outer sleeve, a plurality of beveling grooves are uniformly distributed at the outer ring of the inner sleeve, the end parts of the beveling grooves are matched with the front edges of the swinging blocks, swinging block grooves are uniformly distributed at the inner ring of the outer sleeve, and semicircular shaft holes of the swinging block grooves are matched with back edge half shafts of the swinging blocks. Compared with the traditional overrunning clutch, the swinging type overrunning clutch has the main characteristics that the action among parts during the engaged torque transmission is the simple and direct positive pressure, the extrusion friction does not exist, and the inner sleeve and the outer sleeve of the swinging block are out of contact completely after the disengagement. The swinging type overrunning clutch is mainly applied to the large-scale rotating machine unit auxiliary starting, jiggering, heavy object lifting and the like.
Description
Technical field
The present invention relates to a kind of free wheel device, relate in particular to a kind of swinging type overrunning clutch, for realizing being connected and detachment function of helper motor and main frame, belong to large-scale unit starting, maintenance and weight lift technique field.
Background technique
The free wheel device Wei Wedged piece formula free wheel device that domestic market is most widely used.Wedged piece formula free wheel device mainly is comprised of outer shroud, interior ring and the Ruo Gan Wedged piece that is set on interior ring, and inner and outer rings is connected with working host with helper motor respectively.Interior ring rotates, and Wedged piece and outer shroud compress by friction and drive the outer shroud rotation.Wedged piece formula free wheel device is through the improvement of decades, and material, technological requirement are more and more higher, but because structural type is unreasonable, power effect mode science not, still there is fatal shortcoming: very easily produced blocking under warming, and the larger adhesion of moment of torsion is just more serious, causes clutch malfunctioning, hidden danger causes the accident.
Summary of the invention
The present invention be take and addressed the above problem as purpose, and main the solution certainly now has Wedged piece formula and the overheated easy adhesion of the existing friction of other form free wheel devicees, and causes the malfunctioning technical problem of clutch.
For achieving the above object, the present invention adopts following technical proposals: swinging type overrunning clutch, comprise inner sleeve, overcoat, and above-mentioned inner sleeve is connected with the unit helper motor, and overcoat is connected with main frame.It also comprises centering block, control spring body and bearing support, and the trailing edge semiaxis of described centering block is connected on the axle nest of overcoat inner ring centering block groove in uniform way; Be provided with the control spring body between the front portion of described centering block and overcoat, control spring body pushing centering block leading edge protrudes from the overcoat inner ring; The uniform some grooves of cutting sth. askew in described inner sleeve outer ring, match with the leading edge of centering block in the end of the groove of cutting sth. askew; Described overcoat is provided with the centering block groove in uniform way along inner ring, and the one end is half circular shaft nest, with the trailing edge semiaxis of centering block, matches.
Described centering block leading edge and trailing edge are designed to half shape shaft or the centering block trailing edge are designed to half shape shaft, and leading edge is designed to take the arc that the trailing edge axle center is the center of circle;
Described its end of groove of cutting sth. askew is open circles hole shape axle nest, and its radius is designed to circular arc with the identical end that maybe will cut sth. askew groove of centering block leading edge semiaxis, and its circular arc center of circle is overcoat centering block fluted shaft nest axle center, and its radius of curvature is identical with the leading edge circular arc of centering block.
Working principle of the present invention: under the unit state of rest, the control spring in this swinging type overrunning clutch overcoat centering block groove presses the centering block leading edge to protrude from the overcoat inner ring, relative one by one with the groove of cutting sth. askew of inner sleeve; When helper motor start to drive inner sleeve and rotates, its groove of cutting sth. askew offsets one by one with centering block, drive overcoat slow rotation together with main frame.When unit reaches certain rotating speed; main power machines starts (helper motor shutdown); when rotating speed raising drive overcoat surmounts the inner sleeve rotating speed; the centering block and the inner sleeve that connect on the coat break away from; centrifugal force overcomes the pressure of spring body; centering block is lying in the centering block groove of overcoat together with spring body, realizes that inside and outside cover breaks away from fully, completes the assistant starting of unit.
When host groups, because of maintenance or other reasons shutdown, the control spring in this free wheel device overcoat centering block groove presses the centering block leading edge to protrude from the overcoat inner ring.When needing to start unit or only forwarding unit at a slow speed, start helper motor, drive main frame by this free wheel device and rotate, realize new work cycle.
Secondly, can only start the unit helper motor by this free wheel device band engine block slow rotation, in order to coupling centering diaxon is installed or is kept the unit coasting operation to prevent the main shaft thermal distortion.
Again, starting the unit helper motor by this free wheel device band engine block slow rotation, is the necessary means of large-scale rotation unit inspection and repair shop.
In addition, this free wheel device also can be widely used in the one-way check device of weight elevator system, has eliminated the shortcoming that the intrinsic overheated easy adhesion of friction of other existing one-way check device structures itself was lost efficacy.
Characteristics of the present invention and beneficial effect:
The present invention, owing to adopting centering block to substitute the structural type of voussoir, has solved the problem of existing free wheel device and the overheated easy adhesion of the existing friction of one-way check device.The mode of action of its centering block and inner sleeve is fixed-axis rotation, with the mode of action of overcoat be the simplest malleation, during engagement, each part, without friction, has fundamentally solved the problem that part and part are crossed blocking under warming; After breaking away from, each part does not contact without the friction noiseless.Have compact structure, installation process is simple, low cost of manufacture and long service life, and the clutch freedom and flexibility are without the characteristics of clamping stagnation.Be mainly used in large-scale rotation unit assistant starting, installation and repairing jiggering, unit coasting operation, weight lifting etc.
