Preferably, the teeth of a cogwheel both sides are equipped with the mounting hole, be equipped with the pilot hole on the frame, the frame passes pilot hole and mounting hole connection in proper order on the teeth of a cogwheel through the connecting piece.

Preferably, the connecting member is one of a bolt, a screw and a rivet.

Preferably, the embedding groove is provided with a limiting block, the frame is provided with a limiting groove, and the limiting block is matched with the limiting groove.

Preferably, the inlaid slot includes end slots at both ends of the gear tooth, and side slots at both sides of the top of the gear tooth.

Preferably, the frame comprises an end frame arranged on the end groove and a transverse frame arranged on the side groove.

Preferably, the limiting block is arranged on the side groove, and the limiting groove is arranged on the transverse frame.

Preferably, the frame is made of 12CrNi3A steel.

The beneficial effects of the utility model are concentrated and expressed as follows: this edge strenghthened type bevel gear establishes the frame through inlaying at bevel gear's teeth of a cogwheel border, and its frame is made by 12CrNi3A steel, and surface hardness is high, toughness and moulding are better, can not lead to teeth of a cogwheel border plastic deformation to produce the breach when two bevel gears meshing bearing pressure are great to guarantee that the meshing gear still can keep traction force when the heavy load, bevel gear is unlikely to further worsen the damage, influences equipment operation.

Detailed Description

Referring to fig. 1 to 5, in the present embodiment, the bevel gear with enhanced edge bearing includes a bevel gear body 1 and gear teeth 2 on the bevel gear body 1, the bevel gear body 1 and the gear teeth 2 are designed and manufactured as a whole, and the standard bevel gear may be manufactured from 45 steel, 42SiMn alloy steel, 20Cr carburizing steel, HT300 grey cast iron, QT500-3 ductile cast iron, and the like, in order to prevent the edge of the gear teeth 2 from deforming or notching due to heavy load during meshing transmission, the edge of the gear teeth 2 is recessed with an embedded groove 3, the embedded groove 3 is provided with a frame 4 for protecting the edge of the gear teeth 2, the frame 4 is made of 12CrNi3A steel, the 12CrNi3A steel has high surface hardness, good toughness and shaping performance, and can bear a larger load compared with the gear teeth 2, thereby protecting the gear teeth and saving the gear replacement cost. In order to stably mount the frame 4 in the insert groove 3, the frame 4 is fixed to the gear teeth 2 by a connecting member 5.

Specifically, 2 both sides of the teeth of a cogwheel are equipped with mounting hole 6, and mounting hole 6 establishes the interval and sets up a plurality ofly, be equipped with pilot hole 7 on the frame 4, pilot hole 7 sets up quantity matching with mounting hole 6, frame 4 passes pilot hole 7 and mounting hole 6 through connecting piece 5 in proper order and connects on teeth of a cogwheel 2.

Specifically, the connecting piece 5 is one of a bolt, a screw or a rivet, and has the advantages of low cost, stable fastening and durability.

Specifically, for making frame 4 connect more firmly, inlay and be equipped with stopper 8 on the groove 3, be equipped with spacing groove 9 on the frame 4, stopper 8 matches with spacing groove 9 and suits to it is further spacing with frame 4.

Specifically, the insert groove 3 includes end grooves 10 at both ends of the gear tooth 2, and side grooves 11 at both sides of the top of the gear tooth 2. The frame 4 comprises an end frame 12 arranged on the end slot 10 and a transverse frame 13 arranged on the side slot 11.
