DETAILED DESCRIPTION

[0027] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] Referring to Figures 1 to 11The utility model provides a kind of steel ball type torque limiter, including rotating inner body 1, the rotating inner body 1 left side is equipped with bearing 3, the bearing 3 is equipped with connecting flange 4, the rotating inner body 1 is equipped with steel ball mounting ring 17 on the right side of connecting flange 4, multiple first steel ball placing grooves 18 are equipped on the outer wall of steel ball mounting ring 17, steel ball 5 is equipped on the first steel ball placing groove 18, the right end surface of connecting flange 4 is equipped with convex ring 19, the right end surface of convex ring 19 is equipped with multiple second steel ball placing grooves 20 matched with steel ball 5, the left end of steel ball 5 is located in the second steel ball placing groove 20, the rotating inner body 1 of the right side of connecting flange 4 is equipped with displacement flange 6, the inboard of displacement flange 6 is equipped with third steel ball placing groove 22 matched with the outer end of steel ball 5, the right end surface of displacement flange 6 is equipped with butterfly spring placing groove 21, butterfly spring 7 is equipped in butterfly spring placing groove 21, the right side of displacement flange 6 is equipped with positioning plate 8, the right end outer wall of rotating inner body 1 is equipped with first key groove 16, the positioning plate 8 is equipped with connecting key 14 matched with the first key groove 16, the right side of positioning plate 8 is equipped with torque value scale disc 9, the first bolt mounting hole is equipped on torque value scale disc 9, multiple second bolt mounting holes 13 are evenly equipped on positioning plate 8, adjusting bolt 10 is equipped on the first bolt mounting hole, the left end of adjusting bolt 10 is connected with one of second bolt mounting holes 13, the rotating inner body 1 is equipped with inner hole 11 that is left-right through rotating inner body 1, the second key groove 12 is equipped on inner hole 11, the outer wall of the left end of rotating inner body 1 is equipped with elastic baffle ring 2.Bearing 3 is rolling bearing.Third steel ball placing groove 22 is annular groove matched with steel ball 5.Working, first steel ball placing groove 18, second steel ball placing groove 20 and third steel ball placing groove 33 form a containing cavity containing steel ball 5 between.

[0029] The present technical solution uses torque value scale disc 9 instead of percentage, so that the value of torque value can be accurately obtained, and the disassembly and assembly of the torque limiter can be quickly realized through the elastic baffle ring 2, so that the torque limiter is convenient to replace and maintain.

[0030] Steel ball type torque limiter working principle: when the device transmits torque exceeds the set slip torque (overload), steel ball 5 will leave second steel ball placing groove 20, so that slip occurs between connecting flange 4 and displacement flange 6, at this time, the transmitted torque is reduced to very small, at the same time, steel ball 5 pushes displacement flange 6 to move axially to the right side, triggers sensor or displacement switch, so that sensor output signal is output, and then the output signal can be used to control operation or cut off power source, so that the device stops rotating, and plays a role in protecting the device. After overload is eliminated, steel ball 5 is automatically reset under the action of butterfly spring 7 and the rotation of connecting flange 4 and displacement flange 6, that is, it can automatically restore normal rotation.

[0031] For example, in some embodiments, the first keyway 16 is two, respectively arranged on the outer wall of the rotating inner body 1 at both ends, and the connecting key 14 is two, matched with the two first keyways 16. In this way, the connection between the rotating inner body 1 and the torque value scale disc 9 is more stable.

[0032] For example, in some embodiments, the outer end of the left end surface of the positioning plate 8 is a right-tilted inclined surface. In this way, a gap is left between the second bolt hole 13 and the displacement flange 6, which facilitates the observation of the tightening condition of the adjusting bolt 10 and avoids the influence of the direct contact between the adjusting bolt 10 and the displacement flange 6.

[0033] For example, in some embodiments, the second bolt mounting hole 13 is twenty-four. In this way, the scale position on the torque value scale disc 9 is adjusted.

[0034] For example, in some embodiments, the outer wall of the left end of the rotating inner body 1 is provided with an elastic retainer ring mounting groove 15, and the elastic retainer ring 2 is mounted on the elastic retainer ring mounting groove 15. In this way, the elastic retainer ring 2 is connected more stably. When installing, the positioning plate 8, the butterfly spring 7, the displacement flange 6, the steel ball 5, the connecting flange 4 and the bearing 3 can be sleeved on the rotating inner body 1 from the left end of the rotating inner body 1, and then limited and fixed by the elastic retainer ring 2, which is convenient for operation, installation and maintenance.

[0035] For example, in some embodiments, the steel ball mounting ring 17 is integrally machined with the rotating inner body 1. In this way, the overall structure is more stable.

[0036] In summary, the torque value scale disc is used to replace the percentage, so that the value of the torque value can be accurately obtained, and the rotation time is reduced. The components of the torque limiter can be quickly disassembled and assembled through the elastic retainer ring, which is convenient for replacement and maintenance.

[0037] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
