Problems solved by technology

The helical bevel gear pair is used to transmit the movement and power between two vertically interlaced axes in space. When the helical bevel gear meshes, the meshing line of the gear teeth changes, and the load is gradually added and then gradually removed, so the transmission is relatively stable. , less impact, vibration and noise, suitable for

Abstract

The invention discloses a nonorthogonal conical gear wheel pair, a manufacturing method thereof and a nonorthogonal conical gear wheel limited slip differential consisting of the gear wheel pair, and belongs to the technical field of mechanical driving. The nonorthogonal conical gear wheel pair is characterized by comprising a conical gear wheel (1) and a large gear wheel (2); a helical conical gear wheel axis (3) crosses with a large gear wheel axis (4) in space, and sigma is the fixed included angle of the two axes, and is greater than 0 DEG, but is smaller than 90 DEG; the distance between the two axes is the center distance a of engaging driving; and the nonorthogonal conical gear wheel pair consists of the helical conical gear wheel (1) and the large gear wheel (2) which satisfy the space position relationship of the two axes and the installing distance R1 and R2 of the engaging driving. The nonorthogonal conical gear wheel pair is applied to the motion of the non-90 DEG space crossing axes and the power driving, and the nonorthogonal conical gear wheel limited slip differential is applied to a torque sensing self-locking type differential between axles or wheels of the vehicle.

Description

technical field [0001] The invention relates to a non-orthogonal helical bevel gear pair, a manufacturing method thereof and a non-orthogonal helical bevel gear limited-slip differential composed of the gear pair, belonging to the technical field of mechanical transmission. technical background [0002] The staggered shaft helical cylindrical gear pair can be used for motion and power transmission between the two axis angles ∑ = 0 ~ 90°. When ∑ = 0, it is a line contact, and when ∑ ≠ 0, it is a point contact. The helical bevel gear pair is used to transmit the movement and power between two vertically interlaced axes in space. When the helical bevel gear meshes, the meshing line of the gear teeth changes, and the load is gradually added and then gradually removed, so the transmission is relatively stable. , less impact, vibration and noise, suitable for high-speed, heavy-duty transmission, due to these advantages of helical bevel gears, it occupies an important position in t...
