Description
Technical field
The utility model relates to a kind of free wheel device, relates in particular to a kind of swinging type overrunning clutch, for realizing being connected and detachment function of helper motor and main frame, belongs 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 is mainly 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 outer shroud to rotate.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 mode of action 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 utility model be take and addressed the above problem as object, and main 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 utility model adopts following technical proposals: swinging type overrunning clutch, comprise inner sleeve, overcoat, and above-mentioned inner sleeve is connected with 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; Between the front portion of described centering block and overcoat, be provided with control spring body, control spring body pushing centering block leading edge protrudes from 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 centering block groove in uniform way along inner ring, and its one end is half circular shaft nest, matches with the trailing edge semiaxis of centering block.
Described centering block leading edge and trailing edge are designed to half shape shaft or centering block trailing edge are designed to half shape shaft, and leading edge is designed to take the arc that 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 maybe designed to circular arc by the end of the groove of cutting sth. askew with the identical 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 utility model: under unit state of rest, the control spring in this swinging type overrunning clutch overcoat centering block groove presses centering block leading edge to protrude from 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 to rotate, 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); rotating speed improves while driving overcoat to surmount inner sleeve rotating speed; the centering block and the inner sleeve that connect on the coat depart 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 inside and outside cover and depart from completely, complete the assistant starting of unit.
When host groups is because of maintenance or other reasons shutdown, the control spring in this free wheel device overcoat centering block groove presses centering block leading edge to protrude from overcoat inner ring.When need to start unit or only forwarding unit at a slow speed, start helper motor, by this free wheel device, drive main frame to rotate, realize new work cycle.
Secondly, can only start unit helper motor by this free wheel device band engine block slow rotation, to coupling centering diaxon is installed or is kept unit coasting operation to prevent main shaft thermal distortion.
Again, starting 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.
Feature of the present utility model and beneficial effect:
The utility model, 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 departing from, each part does not contact without friction noiseless.Have compact structure, installation process is simple, low cost of manufacture and long service life, and clutch freedom and flexibility are without the feature of clamping stagnation.Be mainly used in large-scale rotation unit assistant starting, installation and repairing jiggering, unit coasting operation, weight lifting etc.
