Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Refer to Fig. 1, the invention discloses a kind of rotation protection device, comprise the first housing 1, second housing 2, input shaft 3, swing pinion 4, first gear 5 and the second gear 6; First housing 1 and the second housing 2 in the form of annular discs, the center that the center of the first housing 1 is provided with the first centre hole 7, second housing 2 is provided with the second centre hole 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 end and two mirrors to the gear installation end be oppositely arranged, and the input end of input shaft 3 is rotaryed connection with the first housing 1 through the first centre hole 7 of the first housing 1; Two swing pinions 4 are rotaryed connection with two gear installation ends of input shaft 3 respectively; The center of the first gear 5 is provided with the 3rd centre hole 9, the center of the second gear 6 is provided with the output shaft 10 outwards axially protruded, first gear 5 is oppositely arranged with the flank of tooth of the second gear 6 and engages with two swing pinions 4 simultaneously, first gear 5 is rotaryed connection with input shaft 3 by the 3rd centre hole 9, and the output shaft 10 of the second gear 6 is rotaryed connection with the second housing 2 through the second centre hole 8 of the second housing 2.
The present invention can provide actv. torque overload to protect, and guarantees the safety that moment of torsion transmits.Its principle of work is:
Outside torque power parts are connected with input shaft 3, and input shaft 3 is rotated.The swing pinion 4 at now T-shaped input shaft 3 two ends can rotate along with input shaft 3 and circumferentially move, the first gear 5 be engaged with and the second gear 6 due to the moment of torsion between swing pinion 4 very nearly the same, can in the lump with input shaft 3 synchronous axial system, swing pinion 4 now does not relatively rotate relative to the gear installation end of input shaft 3.Second gear 6 is provided with output shaft 10, and therefore the moment of torsion of torque power parts can finally be output axle 10 through a series of transmission and exports.
But when the turning unit be connected with output shaft 10 when outside is stopped and is in overload situations, the moment of torsion between the first gear 5 and the second gear 6 just creates difference.Because the resisting moment of the second gear 6 increases, swing pinion 4 will relatively rotate with the gear installation end of input shaft 3, drives the first gear 5 to do and rotates faster, and that is, the first gear 5 now there occurs relative to the second gear 6 and relatively rotates.Now the second gear 6 is stagnated owing to being subject to outside resistance, all rotary torques are finally delivered to the first gear 5 and are consumed, even if thus keep running also can not form burden to torque power parts for a long time, be equivalent to the outside turning unit be connected with the second gear 6 and occur " skidding ".
First gear 5, second gear 6 can be roughly divided into two kinds with the selection of swing pinion 4.As preferably, described first gear 5, second gear 6 and swing pinion 4 are finishing bevel gear cuter.This structure driven is tight, but can produce axial load to single gear, more applicable in heavily loaded occasion.
Or as preferably another kind of, described first gear 5 and the second gear 6 are imperial crown gear, and described swing pinion 4 is cylindrical wheel.Imperial crown gear can not produce axial load with engaging between cylindrical wheel to single gear, and structure is then comparatively simple, is comparatively applicable to underloading occasion.
Refer to Fig. 2, as preferably, above-mentioned rotation protection device also comprises damping arrangement 11; The outer wall of described first housing 1 is radially provided with damping and regulates tapped bore, damping arrangement 11 is provided with outside thread vertically, the bottom of damping arrangement 11 is provided with rubber cushion, and damping arrangement 11 and damping regulate tapped bore to be threaded, and rubber cushion is to the outside face being located at the first gear 5.
The turning unit be connected with the second gear 6 due to outside unavoidably can be subject to certain resistance less in rotary course, therefore the preferred damping first gear 5 being applied to a balance, in order to avoid rotatable parts skid or loss of machine of torque without reason.And the size of damping determines the response torque of torque overload protection, damping is larger, more difficultly occurs that torque overload is protected; Otherwise damping is less, the response of torque overload protection is easier.Utilize the adjustment of damping, can the response torque of predetermined torque overload protection.
As preferably, above-mentioned rotation protection device also comprises fixed jaw; Fixed jaw comprises and is no less than three activities and refers to, activity refers to the back side be uniformly distributed along the circumference in the first housing 1; The back side of one end that activity refers to and the first housing 1 is hinged, and activity refers to and be provided with torque spring between the first housing 1.
Fixed jaw can be fixed on torque power parts, makes the present invention possess installation commonality.Such as; the present invention is made into general product; originally the family's electric fan not possessing torque overload defencive function installs the present invention additional; safe torque overload defencive function can be produced; shearing accident 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 can not occur.
The invention provides a kind of rotation protection device, can rotation overload protection be carried out, will automatically skid once moment of torsion exceedes preset value, the practical safety of support equipment.Applied range, highly versatile, can be applied to industry or common field of household appliances, guarantee equipment and personal safety.There is fixed jaw structure, convenient to install additional on the slewing of not this structure originally, such as, be installed at the family's electric fan originally not possessing overload protection function.Meanwhile, structure is simple, and easy volume production, using method is easy understand also.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively 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, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
