Description
Technical field
The utility model relates to high ferro accessory, particularly a kind of engaging and disengaging gear.
Background technology
Engaging and disengaging gear on current most of high-speed rail seat, complex structure, manufacturing cost is higher, also has the inferior positions such as operation inconvenience in addition.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of engaging and disengaging gear, and structure is simple, and it is convenient to control
The technical scheme that the utility model adopts is such: engaging and disengaging gear, comprise rotating shaft, be sheathed on the axle sleeve outside described rotating shaft, be sheathed on the drive wheel outside described axle sleeve, the clutch dog be connected by fixed sturcture with described drive wheel, described clutch dog is sheathed in described rotating shaft, described clutch dog and described rotating shaft offer lockhole, in described lockhole, dismounting is provided with stop pin, described axle sleeve offers some perforation, described rotating shaft offers annular guide groove along its periphery, some balls are provided with between described drive wheel and described rotating shaft, described ball is positioned at described perforation and described guide groove.
Further improvement: described fixed sturcture comprise be arranged at some projections in described drive wheel or described both clutch dogs on one, be opened in both in some draw-in grooves on another, described projection matches with described draw-in groove.
Further improvement: described drive wheel is connected with motor by drive belt.
By adopting preceding solution, the beneficial effects of the utility model are: depart from lockhole only by making stop pin and can realize being separated, it is convenient to control, and structure is simple.

Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 4, the utility model discloses a kind of engaging and disengaging gear, comprise rotating shaft 1, be sheathed on the axle sleeve 2 outside described rotating shaft 1, be sheathed on the drive wheel 3 outside described axle sleeve 2, the clutch dog 4 be connected by fixed sturcture with described drive wheel 3, described clutch dog 4 is sheathed in described rotating shaft 1, described clutch dog 4 and described rotating shaft 1 offer lockhole, in described lockhole, dismounting is provided with stop pin 5, described axle sleeve 2 offers some perforation 6, described rotating shaft 1 offers annular guide groove 7 along its periphery, some balls 8 are provided with between described drive wheel 3 and described rotating shaft 1, described ball 8 is positioned at described perforation 6 and described guide groove.
Conveniently manufacture, and structure is simple, described fixed sturcture comprises some protruding 9, the some draw-in grooves 10 be opened in both on another that are arranged in both described drive wheel 3 or described clutch dog 4 on one, and described protruding 9 match with described draw-in groove 10.
In the present embodiment, described drive wheel 3 is connected with motor 12 by drive belt 11.
Principle of work: drive wheel 3 is connected by the fixed sturcture of draw-in groove 10 with projection 9 with clutch dog 4, namely clutch dog 4 is driven to rotate when motor 12 drives drive wheel 3 to rotate, when being connected by stop pin 5 between clutch dog 4 with rotating shaft 1, clutch dog 4 and rotating shaft 1 are fixed as one, rotating shaft 1 is driven to rotate, when stop pin 5 departs from lockhole, clutch dog 4 is separated with rotating shaft 1, when drive wheel 3 drives clutch dog 4 to rotate, rotating shaft 1 can not be rotated thereupon, due to rotating shaft 1 offering guide groove, ball 8 rotates and rotating shaft 1 can not be driven to rotate in guide groove.
More than show and describe groundwork of the present utility model and principal character and advantage thereof; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
