Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention are clearly and completely described.It should be noted that described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of protection of the invention.
Embodiment
Refer to Fig. 1, the invention discloses a kind of rotation protection device, including the first housing 1, the second housing 2, input shaft 3, swing pinion 4, first gear 5 and second gear 6；First housing 1 and the second housing 2 are in the form of annular discs, and the center of the first housing 1 is provided with the first centre bore 7, and the center of the second housing 2 is provided with the second centre bore 8；First housing 1 and the second housing 2 are interconnected to constitute the shell of a hollow；Input shaft 3 is T-shaped, has an input and two mirrors to the gear installation end being oppositely arranged, the input of input shaft 3 passes through the first centre bore 7 of the first housing 1 to be rotatably connected with the first housing 1；Two swing pinions 4 are rotatably connected with two gear installation ends of input shaft 3 respectively；The center of first gear 5 is provided with the 3rd centre bore 9, the center of second gear 6 is provided with the output shaft 10 axially outwardly protruding, first gear 5 is oppositely arranged with the flank of tooth of second gear 6 and is engaged with two swing pinions 4 simultaneously, first gear 5 is rotatably connected with input shaft 3 by the 3rd centre bore 9, and the output shaft 10 of second gear 6 passes through the second centre bore 8 of the second housing 2 to be rotatably connected with the second housing 2.
The present invention can provide the protection of effective torque overload it is ensured that the safety of moment of torsion transmission.Its operation principle is：
Outside torque power part is connected with input shaft 3, so that input shaft 3 is rotated.The swing pinion 4 at now T-shaped input shaft 3 two ends can rotate with input shaft 3 and circumferentially move, the first gear 5 that is engaged with and second gear 6 are very nearly the same due to the moment of torsion between swing pinion 4, can in the lump with input shaft 3 synchronous axial system, swing pinion 4 now do not relatively rotate with respect to the gear installation end of input shaft 3.Second gear 6 is provided with output shaft 10, and the therefore moment of torsion of torque power part can finally be output axle 10 through a series of transmission and export.
But when the rotary part that outside is connected with output shaft 10 is stopped and is in overload situations, the moment of torsion between first gear 5 and second gear 6 just creates difference.The moment of resistance due to second gear 6 increases, and swing pinion 4 will be relatively rotated with the gear installation end of input shaft 3, drives first gear 5 to do faster to rotate that is to say, that first gear 5 now there occurs with respect to second gear 6 relatively rotates.Now second gear 6 is due to being stagnated by outside resistance, all of rotation torque is eventually transferred to first gear 5 and is consumed, even if thus keeping running also will not be equivalent to, to torque power part composition burden, rotary part generation " skidding " that outside is connected with second gear 6 for a long time.
First gear 5, second gear 6 and the selection of swing pinion 4 can be roughly divided into two kinds.Preferably, described first gear 5, second gear 6 and swing pinion 4 are bevel gear.This structure driven closely, but can produce axial load for single gear, more applicable in heavily loaded occasion.
Or as another kind preferably, described first gear 5 and second gear 6 are Phaleria macrocarpa gear, and described swing pinion 4 is roller gear.Phaleria macrocarpa gear will not produce axial load with engaging between roller gear for single gear, and structure is then relatively simple, is relatively applied to underloading occasion.
Refer to Fig. 2 and Fig. 3, preferably, above-mentioned rotation protection device also includes damping unit 11；Damping unit 11 includes adjusting rod 12, damping spring 13 and damping contact 14；The outer wall of described first housing 1 is radially provided with damping and adjusts screwed hole, and the outer wall of adjusting rod 12 is provided with external screw thread, and the end of adjusting rod 12 is provided with a shirt rim extending radially outward, and adjusting rod 12 adjusts screwed hole with damping and threadeds；One end of damping spring 13 is sheathed on the end of adjusting rod 12, and offsets with the shirt rim end face of adjusting rod 12；The other end of damping spring 13 is fixedly connected with damping contact 14, and the end face of damping contact 14 is contacted with the outer surface of first gear 5.
Because the rotary part that outside is connected with second gear 6 can be subject to certain resistance in rotary course less unavoidably, therefore preferred pair first gear 5 applies the damping of a balance, in order to avoid rotatable parts skid or loss of machine of torque without reason.And the size damping determines the response torque of torque overload protection, damping is bigger, is more difficult to torque overload protection；Conversely, damping is less, the response of torque overload protection is easier.Using the regulation of damping, can be with the response torque of predetermined torque overload protection.
The regulation of adjusting rod 12 can be controlled by screw thread, thus adjusting the compression degree of damping spring 13, then damping contact 14 just can be controlled to the contact pressure of first gear 5.The frictional force that damping contact 14 is provided is exactly balance damping referred to above.Meanwhile, this balance damping must be skidded in overload, has damping spring 13 to overcome elastic force to shrink buffering in overload it can be ensured that the overall operationally more steady and smooth of rotation protection device.And in the case of long term overloading work, first gear 5 will not persistently be subject to larger friction to scratch abrasion.This is a sound assurance for the service life of rotation protection device.
Preferably, above-mentioned rotation protection device also includes fixed claw；Fixed claw includes referring to no less than three activities, and activity refers to be uniformly distributed along the circumference in the back side of the first housing 1；One end that activity refers to is hinged with the back side of the first housing 1, and activity refers to be provided with torque spring and the first housing 1 between.
Fixed claw can be fixed on torque power part, makes the present invention possess installation versatility.For example; the present invention is fabricated to general product; install the present invention additional on the family's electric fan originally not possessing torque overload defencive function; safe torque overload defencive function can be produced; make the practicality of family's electric fan safer, even if the blade of electric fan in the both hands touching rotation of child also will not occur shearing accident.
The invention provides a kind of rotation protection device, can carry out rotating overload protection, once moment of torsion exceedes preset value will automatically skid, ensure the practical safety of equipment.Applied range, highly versatile, can apply to industry or common field of household appliances it is ensured that equipment and personal safety.There is fixed claw structure, conveniently install additional on the script not slewing of this structure, for example, be installed at the family's electric fan originally not possessing overload protection function.Meanwhile, structure is simple, is readily mass-produced, using method is also easy to understand.
Embodiment described above only have expressed one embodiment of the present invention, and its description is more concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be defined by claims.
