Description
Technical Field
The invention relates to a torque coupling tripping structure, and belongs to the field of electric tools.
Background
In the design of electric tool products, a large number of torque tripping application scenes exist, such as herringbone groove tripping of an impact wrench or dog tooth tripping of an impact electric drill, but the structure similar to a herringbone groove is complex and high in cost, while a common structure similar to a dog tooth is easy to wear and low in service life, and a torque tripping structure which is simple in structure, low in cost and reliable is lacked.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: how to design a simple, low-cost and reliable structure to replace a common torsion tripping structure so that the structure can complete rolling and axial thrust connection between two parts.
In order to solve the technical problem, the technical scheme of the invention provides a torsion coupling tripping structure which is characterized by comprising an output shaft, wherein the output shaft is provided with threads and is in threaded connection with an end tooth nut, the end tooth nut is connected with a D-hole non-return pad, the D-hole non-return pad is connected with a spring, the spring is connected with a spring washer, the spring washer is connected with coupling steel balls, and the coupling steel balls are connected with a coupling through round holes uniformly distributed on the output shaft.
Preferably, the shaft coupling in be equipped with in can supply the rolling slot of bearing steel ball, the bearing steel ball is connected with the output shaft, guarantees that shaft coupling and output shaft can rotate each other.
Preferably, the coupling is provided with a channel for placing a bearing steel ball and a steel ball cover capable of covering a channel hole.
Preferably, the upper ring spring of the cover is arranged outside the coupler and can cover the steel ball cover, so that the steel ball cover is ensured to be reliably positioned.
The present invention has: the quick installation of ability, reliable shaft coupling, convenient adjustment torsion and low cost's advantage.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present invention relates to a sink type end face steel ball shaft disengaging structure, which comprises: the device comprises an output shaft 6, a coupler 2, bearing steel balls 4, coupling steel balls 5, a steel ball cover 3, a cover upper ring spring 1, a spring washer 7, a compression spring 8, a D-hole non-return pad 9 and an end tooth nut 10.
A semicircular groove is formed in the outer circle of the output shaft 6, a semicircular groove is also formed in the inner hole of the coupler 2, the coupler 2 is sleeved into the output shaft 6, the grooves of the two are aligned, and the bearing steel balls 4 are placed into the grooves through the channel holes in the coupler 2, so that the three form a bearing structure. After the bearing steel balls 4 are arranged, the steel ball cover 3 is arranged, and then the upper cover coil spring 1 is sleeved to complete the thrust positioning and relative rolling of the coupler 2 and the output shaft 6; d hole non return pad 9 is connected to compression spring 8 one side, D hole non return pad 9 links to each other with end tooth nut 10, end tooth nut 10 passes through the threaded connection of internal thread with output shaft 6, compression spring 8 opposite side links to each other with spring washer 7, compression spring 8's packing force is through the equipartition round hole of output shaft 6 to coupling steel ball 5, compress tightly in the heavy hole on 2 terminal surfaces of shaft coupling, make shaft coupling 2 and output shaft 6 not have relative motion, only when torsion reaches enough can make coupling steel ball 5 push away spring washer 7, just two parts have relative motion.
The working process of the structure is as follows: the motor power inputs kinetic energy through the hexagon socket on the coupler 2; the shaft coupling 2 is associated with the output shaft 6 through the bearing steel balls 3 to form radial rolling and axial stopping; the coupling 2 transmits power to an output shaft 6 through a coupling steel ball 5 by a compression spring 8 and a spring washer 7, and a steel ball cover 4 and a cover upper ring spring 1 form an anti-escape system of a bearing steel ball 3.
