Preferably, the front threaded connection of connecting plate has a plurality of fixing bolt, a plurality of bolt holes have all been seted up in the front of mounting groove and the front of spread groove, and a plurality of fixing bolt's one end extends to inside and bolt hole threaded connection of the inside bolt hole of spread groove and mounting groove respectively.

Preferably, the spacing groove has all been seted up to the top and the bottom of mounting groove and the top and the bottom of spread groove, the top and the bottom of connecting plate all are fixed with the stopper, and one side of two stoppers all extends to the inside and the spacing groove sliding connection of spacing groove.

Preferably, the outer walls of the two fixing rings are provided with fixing holes, and the fixing holes are communicated with the fixing grooves.

Preferably, the inner wall of the fixing hole is provided with threads.

The invention has the beneficial effects that:

1. through the cooperation between solid fixed ring, semi-gear a, semi-gear b, mounting groove, spread groove, connecting plate, fixing bolt and the bolt hole, conveniently get up semi-gear a and semi-gear b combination and fix on the transmission shaft, also conveniently dismantle semi-gear a and semi-gear b from the transmission shaft.

2. Through the cooperation between fixed slot and the fixed orifices, conveniently utilize the bolt to further fix two solid fixed rings on the transmission shaft to gear stability at the during operation has been strengthened.

The gear mounting device has the advantages of stable structure and simple operation, can conveniently mount the gear on the transmission shaft and dismount the gear from the transmission shaft, thereby facilitating the replacement of the gear by maintainers and being easy to popularize and use.
