SUMMERY OF THE UTILITY MODEL
The present invention is directed to a polygonal fixed flywheel mounting assembly to solve the above-mentioned drawbacks of the prior art.
In order to realize the purpose, the utility model adopts the following technical scheme: polygonal fixed flywheel installation combination comprises an end cover body and a flywheel body, wherein a connecting shaft is arranged on the right side face of the end cover body, a side surface of the connecting shaft is provided with a first molded surface, a mounting groove is formed in the front surface of the flywheel body, a second molded surface is arranged on the inner side surface of the mounting groove, a clamping groove is formed in the side surface of the second molded surface, and the end cover body is connected with the flywheel body through a clamping spring for clamping a clamping block and a shaft.
As a further description of the above technical solution:
the quantity of first profile and second profile is six, first profile cooperatees with the second profile.
As a further description of the above technical solution:
the position of the flywheel body is located on the first molded surface, and the position of the shaft clamp spring is located on the side surface of the flywheel body.
As a further description of the above technical solution:
the position of the clamping block is located in the clamping groove, and the clamping block is movably connected with the clamping groove.
The utility model discloses following beneficial effect has:
compared with the prior art, this fixed flywheel installation combination of polygon through setting up draw-in groove, for the axle jump ring, increases the individual item location and offsets machining tolerance, ensures the fastening, has prevented flywheel body installation back axial displacement effectively simultaneously, takes place the phenomenon that the pine takes off, improves the device's practicality.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-7, the present invention provides an embodiment: fixed flywheel installation combination of polygon, including end cover body 1 and flywheel body 3, the right flank of end cover body 1 is provided with connecting axle 2, the side surface setting and first profile 21 of connecting axle 2, first profile 21 is six with the quantity of second profile 32, six profiles form the hexagon, make things convenient for a profile to cooperate even, first profile 21 cooperatees with second profile 32, the front surface of flywheel body 3 is provided with mounting groove 31, the mounting groove 31 medial surface is provided with second profile 32, draw-in groove 33 has been seted up to the side surface of second profile 32, end cover body 1 passes through fixture block 4 with flywheel body 3, axle is connected with jump ring 5, the position of flywheel body 3 is located first profile 21 side surface, axle is located the side surface of flywheel body 3 with the position of jump ring 5, the position of fixture block 4 is located the inside of draw-in groove 33, and fixture block 4 and draw-in groove 33 swing joint.
Through setting up this structure, through draw-in groove 33, for the axle jump ring 5, increase the individual item location and offset machining tolerance, ensure the fastening, prevented 3 installation back axial displacement of flywheel body, pine simultaneously effectively and taken off, improve the device's practicality.
The working principle is as follows: when the flywheel connecting shaft is used, the first molded surface 21 on the connecting shaft 2 is matched with the second molded surface 32 on the inner side surface of the mounting groove 31 on the flywheel body 3, the flywheel body 3 can be sleeved on the second connecting shaft 2, the clamping block 4 is installed in the mounting groove 31, and finally the clamp spring 5 for the shaft is installed on the flywheel body 3, so that the phenomenon that the flywheel body is loosened due to axial movement after being installed can be effectively prevented.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
