In various mechanical transmissions, the transmission efficiency of the spiral bevel gear is the highest, and the spiral bevel gear transmission has great economic benefit for various transmissions, particularly high-power transmission; the transmission pair of the transmission part required when transmitting the same torque saves the space most and has smaller space size than the belt and chain transmission; the transmission ratio of the spiral bevel gear is permanently stable, and the stability of the transmission ratio is often the basic requirement on the transmission performance in the transmission of various mechanical equipment; the spiral bevel gear works reliably and has long service life.
The connection of key between current spiral bevel gear and the axle is through the key-type, and the key-type makes the clearance grow between spiral bevel gear and the axle for take place the deflection of certain angle between spiral bevel gear and the axle, thereby make the tooth between the gear can not mesh completely, can make the gear wearing and tearing for a long time, reduce the life of gear.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve and to have passed through the key-type connection between current spiral bevel gear and the axle, and the key-type connection makes the clearance grow between spiral bevel gear and the axle for take place the deflection of certain angle between spiral bevel gear and the axle, thereby make the tooth between the gear can not the complete meshing, can make the gear wearing and tearing for a long time, reduce the life's of gear problem, a spiral bevel gear has now been provided.
The utility model provides a technical scheme that its technical problem adopted is: a spiral bevel gear comprises a body, wherein one end of the body is provided with a gear tooth part, the other end of the body is provided with a shaft hub, the body is provided with a shaft hole, the shaft hole extends from one end of the body to one end of the shaft hub, which is far away from the body, the outer peripheral surface of the shaft hub is provided with a first notch along the radial direction, the first notch extends from the outer peripheral surface of the shaft hub to the inner peripheral surface of the shaft hole, the outer peripheral surface of the shaft hub is provided with a second notch along the axial direction, the second notch extends from the outer peripheral surface of the shaft hub to the inner peripheral surface of the shaft hole, the first notch is positioned between the second notch and the body, one end of the second notch is communicated with the first notch, the other end of the second notch penetrates through one end of the shaft hub, which is far away from the body, the shaft hub is provided with a first through hole and a second through hole along the radial, the first through hole and the second through hole are correspondingly arranged. Through set up first notch and second notch on the shaft hub, form two clamping pieces that can deform on the shaft hub by first notch and second notch to it is fixed with the splint of second notch both sides to pass first through-hole and second through-hole through the screw, rotate the screw, make both sides splint hold the axle in the shaft hole tightly, thereby realize fixing the gear epaxial.
The utility model has the advantages that: when the spiral bevel gear of the utility model is used, two deformable clamping pieces are formed on the shaft hub by the first notch and the second notch through the first notch and the second notch arranged on the shaft hub, the clamping plates at the two sides of the second notch are fixed by the screws penetrating through the first through hole and the second through hole, the screws are rotated to enable the clamping plates at the two sides to tightly hold the shaft in the shaft hole, thereby realizing the fixation of the gear on the shaft, the shaft and the shaft hub are fixed in a holding manner, the clearance between the shaft and the shaft hub is reduced, the transmission precision between the gears is ensured, the prior spiral bevel gear is prevented from being connected with the shaft through a key, the key connection makes the gap between the spiral bevel gear and the shaft enlarged, so that the spiral bevel gear and the shaft deflect at a certain angle, therefore, the teeth between the gears can not be completely meshed, the gears are abraded for a long time, and the service life of the gears is shortened.
