Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 and fig. 2, the embodiment of the utility model provides a wheel limit motor fixed knot constructs, which comprises a housing 1, adorn stator 7 in casing 1 admittedly, install front end housing 2 and rear end housing 5 at casing 1 both ends respectively, adorn the bearing admittedly on the front end housing 2, install rotor 6 through bearing rotation on the front end housing 2, front end housing 2 of motor passes through reducing gear box flange 3 and can dismantle with the reducing gear box and be connected, reducing gear box flange 3 one end sets up flange 31, flange 31 cross section diameter is greater than reducing gear box flange 3 cross section diameter, 2 one end of front end housing sets up locking ring 22, the diameter of locking ring 22 is greater than 2 cross section diameters of front end housing, set up a plurality of screw holes on the locking ring 22, set up the trompil that corresponds with screw hole on the locking ring 22 on the flange 31, locking.

As shown in fig. 2, a flange convex ring 32 is arranged at the end of the flange 31, and a positioning groove 23 for matching and positioning with the flange convex ring 32 is arranged at the end of the locking ring 22; the flange convex ring 32 is completely inserted into the positioning groove 23, and positioning between the flange convex ring 31 and the locking ring 22 is realized.

As shown in fig. 2, a front bayonet 11 and a rear bayonet 12 are respectively formed at two ends of the housing 1, a front protrusion 21 is arranged at one end of the front end cover 2, a rear protrusion 51 is arranged at one end of the rear end cover 5, and the front protrusion 21 and the rear protrusion 51 are respectively used for being clamped into the front bayonet 11 and the rear bayonet 12; the front end cover 2 and the rear end cover 5 are arranged at two ends of the machine shell 1 through the convex matching bayonets, and the utilization rate of the inner space of the machine shell 1 is improved.

As shown in fig. 2, one end of the rotor 6 passes through the rear end cover 5, a bearing matched with the rotor 6 is installed on the rear end cover 5, and a bearing installation sheet 8 for fixing the bearing is installed on the rear end cover 5 through a bolt; the rear end cover 5 is provided with a bearing matched with the rotor 6, so that the rear end cover 5 is more stably arranged at one end of the machine shell 1, and the rotor 6 rotates more stably.
