Technical field
The utility model is the improvement about the differential mechanism lubricating system, relates in particular to the circulation cooling lubrication device of Horizontal spiral discharging centrifuge with differential mechanism.
Background technique
There are two kinds of different output speeds in differential mechanism, although the numerical value of the speed of these two kinds of output speeds differs
Less, but two be all high-speed motion, therefore can produce a large amount of heat, prior art is to utilize splash lubrication side
Formula is taken away heat energy, and effect is poor, causes differential mechanism overheated, and the part in differential mechanism is killed, and forms the parking thing
Therefore.
China Patent Publication No. is CN1470781, discloses a kind of interaxial differential assembly with lubricant pump.Pump is installed between differential mechanism input and output axle, by with output shaft, be connected or hole that the all-in-one-piece side gear is definite in.Pump has housing, and housing has first and second mouthfuls and at the curve bath of radially-outer surface.Pin from side gear radially extend internally and insertion groove in.Groove and pin coordinate rotates whole pump energy opposite side gear, and therefore changes the position of two mouths.Like this, this assembly provides the pump that the Double-directional rotary of supply of lubricant while relatively rotating is only arranged between differential mechanism input and output axle, it solves the problem of splash lubrication by set up lubricant pump in differential mechanism, and can't make the high temperature grease in running discharge and recycle.
China Patent Publication No. is CN201568559U, discloses a kind of differential lubricating device, comprises differential mechanism, differential mechanism axle housing and clamping bolt, and this device is provided with oil skipper on the differential mechanism axle housing.This differential lubricating device, under vehicle bridge running environment, guarantee that in axle housing, lubricant oil fully stirs and splashes, and contributes to the sufficient lubrication of the lubricated and drive bevel gear bearing of differential assembly.Can be not overheated because of lack of lubrication or the lubricated assembly caused not in place, mechanism's sintering.Reduce the working life of assembly.Its principle is also to adopt to set up oil skipper, utilizes splash lubrication, though lubrication effect is improved, effect is also not obvious.
China Patent Publication No. is CN101881331A, a kind of auxiliary lubricating system of differential is disclosed, comprise lubricant pipe (3), locking plate (2) and locking plate fixing bolt (1), wherein lubricant pipe (3) is arranged on the upper reserved oil duct place of torque-converters housing (7), one end of locking plate locks onto torque-converters housing (7) by locking plate fixing bolt (1), the other end is pressed in lubricant pipe (3) thereby upper fixedly lubricant pipe (3), lubricant pipe (3), by the aperture on it, carries out enforced lubricating to differential mechanism central gear position.The utility model compact structure and simple, be convenient to manufacture and assembling, reliability is high, thereby solved few, the lubricated difficult lubricated difficult problem of automatic transmission differential mechanism of gear oil mass, the wearing and tearing of differential gear have been slowed down, improved differential mechanism working life, its structure is reserved oil duct in housing, insert lubricant pipe and carry out enforced lubricating, although overcome the problem of splash lubrication weak effect, its structure is comparatively complicated, need separately set up parts, and lubricant oil can not be recycled, be had much room for improvement.
Summary of the invention
The utility model, for solving the problems of the technologies described above, provides a kind of differential mechanism excessive velocities that effectively overcomes, and the too high part that causes of inner body temperature rise is killed formation parking accident, high lubricating effect, lubricated improved differential lubricating device capable of circulation.
The utility model is for above-mentioned technical problem, provide following technological scheme: a kind of improved differential lubricating device, comprise differential mechanism, with differential mechanism, be connected for placing restrictions on the coupling shaft of torque, it is characterized in that described coupling shaft is hollow shaft, coupling shaft one end connected with differential, one end connects swivel joint, be provided with hollow tubular in coupling shaft, hollow tubular one end is communicated with swivel joint, swivel joint connects oil pump, the hollow tubular the other end is communicated with hollow gear shaft in differential mechanism, offers single or multiple oil transportations hole on hollow gear shaft.
As further improvement of the utility model, described coupling shaft has oblique or straight single or multiple circulation oilholes on the axial wall that stretches into differential mechanism one end, described circulation oilhole is communicated with the center hole of coupling shaft, has the draining hole be communicated with center hole on the connection axial wall of swivel joint one end.By this kind of setting, utilize siphon principle cooling by discharging in center hole in high temperature lubricating liquid suction coupling shaft.
Preferably described circulation oilhole is set to lead to the level, vertical four of coupling shaft center hole as of the present utility model, and each hole all separately offers an inclined hole and is communicated with it, described level, vertical four recycle oil bore ends sealing.By this kind, the kinetic transformation that centripetal pump takes full advantage of liquid is set and becomes pressure energy.The liquid kinetic transformation is become the process of pressure energy carry out in the runner of centripetal pump, when differential mechanism inside is full of oil, the High Rotation Speed of differential mechanism drives oily High Rotation Speed, diagram oil is flow at high speed tangentially in the outer rim of centripetal pump, the purpose of this kind of perforate direction is the resistance produced in order to reduce when liquid enters runner as far as possible, can better carry out transformation of energy.Kinetic energy is converted to pressure energy: when differential mechanism inside is full of oil, it is large that internal pressure becomes, and forces liquid to be walked toward the place of low pressure, and after liquid tangentially enters runner, liquid moment is full of centripetal pump inside, and because inner passage is narrow and small, it is large that natural pressure just becomes.
The utility model purpose realizes, mainly improves and is to change utilize the splash lubrication mode to take away the mode of heat energy as pressure lubrication circulating cooling mode into.Specifically, the utility model differential mechanism former with change hollow shaft into for placing restrictions on the solid coupling shaft that torque is connected, a hollow tubular is installed in the middle of hollow shaft, advance circulation cooling lubrication in the middle of hollow tubular, hollow tubular one end is connected with swivel joint, utilizes pump to carry out the feed liquor work of circulating cooling liquid.Cooling-lubricant arrives differential mechanism inside by hollow tubular, the effect of lubrication and cooling moving parts is played on the surface that utilizes oblique or straight single or multiple apertures on hollow gear shaft to be dispersed to the differential mechanism moving parts under the drive of differential mechanism lower velocity shaft, the Lubricants of the relatively-high temperature of process lubrication and cooling utilizes the high-speed motion of differential mechanism shell, by opening oblique or straight single or multiple apertures on the axial wall of hollow shaft and utilize siphon principle to discharge fast high-temp liquid placing restrictions on solid shaft that torque connects and change into, high-temp liquid is through supercooling, then circulated by pump.
The beneficial effects of the utility model: the utility model is by making hollow shaft at coupling shaft, and oil pipe is set within it, splash lubrication in differential mechanism is changed into to pressure lubrication, and stretching at coupling shaft on the axial wall of differential mechanism one end and having oblique or straight single or multiple circulation oilholes, utilize the siphon principle circulating cooling, greatly improved cooling effectiveness, effectively overcome the differential mechanism excessive velocities, the too high part that causes of inner body temperature rise is killed formation parking accident.
