Abstract
An ultralarge size overdrive clutch mainly comprises a connecting flange1, a bearing 2, an auxiliary axis3, an outer ring of the clutch4, a slide check ring5, a spring6, a spring mandrel7, a fixing sleeve8, an associator9, a spring10, and an inner ring of the clutch11, etc. The utility model has the advantages of large transmitting power, high speed, no impact and low noise which mainly applies to the occasion that a starting electric motor drives a main electric motor with large power to start.
Description
Affiliated technical field
The utility model belongs to a kind of actuating unit.
Background technique
Common free wheel device is a kind of pawl type mono-directional overrun clutch, is mainly used in the occasion that prevents to reverse and need intermittent motion.Its mechanism is simple, mainly form: ratchet, ratchet, ratchet mandrel and outer shroud by following part, when the ratchet rotating speed is higher than outer shroud, ratchet passes motion to outer shroud by ratchet and mandrel, when outer shroud speed is higher than ratchet, then outer shroud surmounts ratchet and rotates alone, surmounts in the rotation, and ratchet and ratchet break away from.This clutch configuration is simple, and is easy to manufacture, the reliability height.But in conjunction with the time have and impact and noise, generally can only be used for low speed and stressed little occasion.
Summary of the invention
Can not bear the deficiency of high-speed overload in order to overcome existing overrun, task of the present utility model is that a kind of transmitted power of design is the maximum free wheel device in the whole nation.
The technological scheme that its technical problem that solves the utility model adopts is: its interior ring 11 and starting electrical machinery link, clutch outer shroud 4 links with connecting flange 1, coupling on connecting flange 1 and the main motor links, and be bearing on the auxiliary axis 3 by two bearings 2, auxiliary axis 3 is fixed in the clutch and encircles on 11, and slippage back-up ring 5 holds out against the right flank at zygote 9 under the effect of spring 6.Four zygotes on this clutch during work, because the zygote mandrel does not stress, are to come this problem of transmitting torque by the ratchet mandrel thereby solved free wheel device commonly used through particular design, have further improved the ability of this clutch transmission torque.
The utility model is compared with prior art has following advantage:
1. transmitted power is big, the speed height, and power loss is little.
2. do not have impact, noise is little, and function admirable is safe and reliable.
3. simple in structure, floor space is little.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is A-A cut-away views of accompanying drawing 1
1. connecting flanges among the figure, 2. bearing, 3. auxiliary axis, 4. clutch outer shroud, 5. slippage back-up ring, 6. spring, 7. central spindle of the spring, 8. fixed cover, 9. zygote, 10. spring, ring in 11. clutches.
Embodiment
Shown in accompanying drawing 1, accompanying drawing 2, clutch of the present utility model is linked with starting electrical machinery by ring 11 in the clutch, clutch outer shroud 4 links with connecting flange 1, coupling on connecting flange 1 and the main motor links, and be bearing on the auxiliary axis 3 by two bearings 2, auxiliary axis 3 is fixed in the clutch and encircles on 11, and slippage back-up ring 5 holds out against the right flank at zygote 9 under the effect of spring 6.
When starting electrical machinery starts, ring 11 clockwise directions rotation in the clutch, zygote 9 by several particular design drives clutch outer shroud 4, connecting flange 1 and the rotation synchronously of main motor do, when near the rated speed of main motor, several zygotes 9 are thrown off simultaneously, and under centrifugal action, zygote 9 is attached on the inwall of clutch outer shroud 4 and rotates synchronously with outer shroud, no longer contact with interior ring 11 and slippage back-up ring 5, not friction.When zygote 9 was thrown off, slippage back-up ring 5 is slippage forward under the effect of spring 6, withstood in the clutch and encircled on the 11 right side step surfaces.At this moment starting electrical machinery outage stops, and outer shroud 4 is followed the long-term dry running of main motor, and clutch has only two block bearings 2 in work, and power loss is very little.
When unit stopped, clutch outer shroud 4 stopped, and zygote 9 drops on the slippage back-up ring 5 under gravity and spring 10 power effects, did not contact with interior ring 11, did not impact.When unit will restart, allow slippage back-up ring 5 slippage to the right, zygote is adjacent under gravity and spring force effect, zygote is resetted on the interior ring.
Slippage back-up ring 5 plays the safety protection effect; in the unit starting process; when the startup of can not normally closing a floodgate of main motor; under the situation that starting electrical machinery does not stop, very fast if main motor speed descends, zygote 9 loses centrifugal force; it also can only fall on the cylindrical of slippage back-up ring 5; can not contact, mesh, prevent that clutch from meshing the enormous impact of generation once more, protected whole unit effectively with interior ring 11.
Accompanying drawing 1, accompanying drawing 2 are one of embodiments of the present utility model.
Accompanying drawing 1, accompanying drawing 2 are a kind of super-huge free wheel device schematic representation, and all parts all adopt the conventional material manufacturing and choose commercially available fabricated part and assemble.Its important technological parameters is:
Rated torque: 32KNm;
Maximum Torque: 64KNm;
Maximum speed: 1500r/min;
Claims (1)
1. super-huge free wheel device.Its interior ring 11 and starting electrical machinery link, clutch outer shroud 4 links with connecting flange 1, coupling on connecting flange 1 and the main motor links, and be bearing on the auxiliary axis 3 by two bearings 2, auxiliary axis 3 is fixed in the clutch and encircles on 11, and slippage back-up ring 5 holds out against the right flank at zygote 9 under the effect of spring 6.It is characterized in that: when clutch outer shroud speed greater than clutch in ring during speed, the zygote of four particular design is thrown off simultaneously, under centrifugal action, zygote is attached on the inwall of clutch outer shroud and rotates synchronously with outer shroud, no longer contacts with interior ring, not friction.Have that transmitted power is big, speed is high and characteristics such as power loss is little.
