Abstract
The utility model discloses a kind of novel large speed ratio hypoid gear, include the eccentric driving gear, the driven gear that coordinate, described driving gear is helical bevel gear, described driven gear is spiral bevel gear, the ratch portion of driving gear has the teeth groove of annular arrangement, the internal diameter of driven gear is 180mm, and external diameter is 320mm, and the flank of tooth tap web of helical bevel gear and the spacing of flank of tooth ear end face are 160mm.Velocity ratio of the present utility model is 8.17, and driven gear maximum outside diameter is only Φ 320.Through the optimization to gear root R angle, the optimization of modulus and the improvement to techniques such as gear heat treatment and the flank of tooth have sprayed, be this hypoid gear as calculated, driven gear max. output torque is greater than 11000N.m.Meet the performance requirement of client to car load.
Description
Technical field
The utility model is mainly used in the industrial vehicle and machinery pursuing big retarding ratio, is especially useful in the novel large speed ratio hypoid gear of one of the special dimensions such as the ransaxle of the demand weight tractions such as airport, harbour, large ship.
Background technique
Hypoid gear is the bevel gear of axis bias, and habituation is named " hypoid gear ", also cries " hypoid gear " or " hypoid gear ", is mainly used in transmitting the motion between alternating axis and power.Hypoid Gear Drives is more steady than spiral bevel gear transmission; Utilize Offset to increase little wheel diameter, thus can increase steamboat rigidity, realize two supports, be therefore widely used in go-anywhere vehicle, minibus and truck to improve or to reduce vehicle's center of gravity.
The single reduction gear reduction speed ratio of current domestic apolegamy hypoid gear is generally 3.5-6.7, and too large velocity ratio will make the oversize of driven wheel of differential, affects the ground Clearance of driving axle housing.Ground Clearance is less, and automobile passability is poorer, which also limits the overall dimensions of driven spur gear.But the velocity ratio of maximum 6.7 is applied in narrow space, circumstance complication, tractive force, driving force are required that high special special purpose vehicle field cannot meet far away.Because this field has higher requirements to vehicle size and tractive force, by the restriction of vehicle structure and layout, a unconventional large speed ratio of active demand and driven gear maximum outside diameter can not exceed the hypoid gear of driving axle housing clearance, to meet car load usage requirement.
Model utility content
The purpose of this utility model is to provide a kind of novel large speed ratio hypoid gear, and velocity ratio is 8.17, and driven gear maximum outside diameter is only Φ 320.Through the optimization to gear root R angle, the optimization of modulus and the improvement to techniques such as gear heat treatment and the flank of tooth have sprayed, be this hypoid gear as calculated, driven gear max. output torque is greater than 11000N.m.Meet the performance requirement of client to car load.
The technical solution of the utility model is as follows:
A kind of novel large speed ratio hypoid gear, include the eccentric driving gear, the driven gear that coordinate, described driving gear is helical bevel gear, described driven gear is spiral bevel gear, the ratch portion of driving gear has the teeth groove of annular arrangement, the internal diameter of driven gear is 180mm, and external diameter is 320mm, and the flank of tooth tap web of helical bevel gear and the spacing of flank of tooth ear end face are 160mm.
Described driving gear and the throw of eccentric of driven gear are 6-7mm.
Velocity ratio of the present utility model is 8.17, and driven gear maximum outside diameter is only Φ 320.Through the optimization to gear root R angle, the optimization of modulus and the improvement to techniques such as gear heat treatment and the flank of tooth have sprayed, be this hypoid gear as calculated, driven gear max. output torque is greater than 11000N.m.Meet the performance requirement of client to car load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
