Description
Technical field
The invention belongs to machinery manufacturing technology field, specially refer to a kind of Hypoid Gear Drives mechanism.
Background technique
A pair of hypoid gear pair driving mechanism all is set in automobile usually,, realizes the moment of torsion transmission between motor and the wheel to change the torque direction of motor.Traditional Hypoid Gear Drives mechanism structure as shown in Figure 1, driving shaft 10 and driven shaft 13 are by 90 ° of engagements of 4 one-tenth crossed axis angles of a pair of hypoid gear pair.When driving shaft 10 receive pass over torque from motor after, drive driven shaft 13 and rotate, realize torque break-in transmission, rotate with driving wheel, towing motorcar advances or retreats.In this process, driving shaft 10 will be born the reaction force that produces when coming from gear pair 4 engagements in rotation, promptly bear the radial load and the bearing load effect that come from reaction force.Because the effect of these two kinds of load, driving shaft 10 will produce deflection in rotation, therefore, support driving shaft 10 with a pair of tapered roller bearing 11 and 12, the deflection that the driving shaft 10 that is used to suppress to be caused by above-mentioned two kinds of load produces makes it reach the requirement of required load-bearing ability, durability, rigidity.
At tapered roller bearing 11(12) in, roller 6(9) and interior ring 5(8), and roller 6(9) with outer shroud 2(3) respectively line contact, so that whole line contact segment is born radial load and thrust load from driving shaft 10, utilize the pretension in the axial direction of the locking nut 1 of axle sleeve 7 and hull outside simultaneously, make tapered roller bearing 11(12) pretightening force reach certain level, and guarantee that its rigidity can meet the demands.
In order to satisfy tapered roller bearing 11(12) support desired enough durability and rigidity, keeping enough to it, the lubricated of necessity seems of crucial importance.When driving shaft 10 rotates, can stir lubricant oil simultaneously, make lubricant oil enter into tapered roller bearing 11(12) roller 6(9) and interior ring 5(8) and roller 6(9) and outer shroud 2(3) between so that the formation oil film.And, adopt full-bodied oil product to be lubricated usually in order more to be easy to generate oil film.Driving shaft 10 rotating speed when work is very high in addition, the surface friction drag that produces when it rotates is bigger, easily produce higher heat, its lubricated environment requires more strict comparatively speaking, insufficient lubrication may appear under some extreme case for causing the bearing burn, the gummed phenomenon takes place, and therefore must increase lubricants capacity.
In sum, mainly there is following problems in the above-mentioned Hypoid Gear Drives device that utilizes tapered roller bearing to support: when 1, tapered roller bearing was worked, roller was that line contacts with inner and outer rings, and running resistance is big; 2, lubricants capacity is big, and the kinetic energy of churning loss is big; 3, for easier formation oil film, be lubricated, increased and stirred oily resistance with full-bodied oil product; 4, tapered roller bearing uses in pairs, and pretension is carried out with axle sleeve in the centre, and the arrangement space that driving mechanism takies is big, has increased the weight of device, thereby has influenced the lightweight of automobile.
Summary of the invention
The objective of the invention is to propose a kind of Hypoid Gear Drives mechanism, under the prerequisite that guarantees enough support stiffness and life requirement, reduce the loss of lubricants capacity and gearing friction, compact structure simultaneously, but the high pass efficient and the lightweight requirements of implement device.
Hypoid Gear Drives of the present invention mechanism comprises the driving shaft and the driven shaft that are the 90 degree angles of cut that is arranged in the housing, and described driving shaft utilizes hypoid gear pair to be connected with driven shaft; Key is also to comprise an axial limiting in the double-row angular contact bal bearing of driving shaft axis body, and the outer shroud and the inner walls of described double-row angular contact bal bearing offset, and inner ring sleeve is connected on the axis body of driving shaft; Described double-row angular contact bal bearing is provided with and is communicated with its oil duct inner and the enclosure interior cavity.
The present invention utilizes a double-row angular contact bal bearing to support the axis body of driving shaft, this kind bearing inside is provided with a pair of relative angular contact ball bearing, and the mounting point of two angular contact ball bearings is very near, almost be close together, the intersection point that is subjected to the line of force of this angular contact ball bearing is its equivalent strong point, and the spacing between the strong point is to support brachium.Adopt this supporting way, its support arm is longer, and the close hypoid gear pair of the strong point, therefore can effectively bear radial load and the thrust load that acts on the driving shaft axis body, satisfies required rigidity of support requirement.The length of this double-row angular contact bal bearing is significantly smaller than the length of tapered roller bearing, and therefore compact structure on arranging can effectively be saved between appearance the miniaturization lightweight of implement device.In addition, because the inside and outside circle of angular contact ball bearing and ball all are to contact, surface friction drag is minimum, require less to lubricants capacity, and also lower to the oil viscosity requirement, the churning loss that produces in the whole operation process and the heat loss of generation are all very little, can effectively improve transmission efficiency.
Further, the locking nut of the axis body of described driving shaft is arranged on the end near hypoid gear pair, makes full use of the space in the housing, can save required axial arranged space like this, the miniaturization of implement device and lightweight.
Specifically, described oil duct is for entering into the through hole of cavity between double-row angular contact bal bearing ball and interior ring, the outer shroud via the outer ring surface of double-row angular contact bal bearing and sidepiece, when driving shaft rotates, lubricant oil in the housing is stirred by gear pair, be splashed to the outer ring surface and the sidepiece of double-row angular contact bal bearing, enter into cavity between ball and interior ring, the outer shroud by oil duct again, the ball surface and in the inner side surface formation oil film of ring, outer shroud, double-row angular contact bal bearing is lubricated.
The axial limiting mode of described double-row angular contact bal bearing has following two kinds: 1, the projection that is provided with on the axis body of a side of described double-row angular contact bal bearing and driving shaft offsets, and the madial wall of opposite side and housing offsets.This kind mode is simple in structure, is easy to processing and assembling.2, the projection that is provided with on the axis body of a side of described double-row angular contact bal bearing and driving shaft offsets, and opposite side and an interior edge face that is fixedly connected on the flange shaft on the driving shaft axis body offset.This kind mode can be regulated the degree that compresses to double-row angular contact bal bearing by the axial position of regulating flange shaft, thereby makes the hypoid gear pair engagement fit better effects if of driving shaft and driven shaft.
Above-mentioned projection can also can be the gear of driving shaft for being fastened on the snap ring on the driving shaft axis body, directly utilizes the gear mesh double-row angular contact bal bearing to carry out axial limiting and can save cost.
Hypoid Gear Drives mechanism structure compactness of the present invention, keeping enough support stiffness, bear under the prerequisite of necessary radial load and thrust load, saved arrangement space, alleviated overall weight, and required lubricants capacity is few, viscosity to oil product requires extremely low, produce to stir oily energy loss minimum, low speed and when running up the gearing friction drag losses minimum, improved transmission efficiency, be applied to automobile particularly in the drive system structure of all-wheel drive vehicle, can effectively improve automobile fuel ecomomy, bring huge economic benefit.
