Abstract

The utility model discloses a loader gearbox self-lubricating device comprising a semi-closed U-shaped oil groove including a front U-shaped groove and a rear U-shaped groove, a front lubricating oil pipe arranged outside a front shell and a rear lubricating oil pipe arranged outside a rear shell. The gearbox triple shaft center is axially provided with a large through hole, a small through hole communicated with the large hole is formed in the position adjacent to a friction sheet assembly and a bearing radially, and two ends of the triple shaft are provided with extension pipe joints extending out of the shells corresponding to the large through hole; the semi-closed U-shaped oil groove is located above a triple-shaft clutch, and two ends are provided with pipe joints extending out of the shells; the front shell and the rear shell are provided with two screwed holes used for connecting the pipe joints and the extension pipe joints; the upper ends of the front lubricating oil pipe and rear lubricating oil pipe are connected to the pipe joints, the lower ends are connected to the extension pipe joints, and the semi-closed U-shaped oil groove is communicated with the oil way of the large through hole. The loader gearbox self-lubricating device is capable of lubricating gearbox friction sheet assemblies completely without an external cooling system, and the purpose of prolonging service life of the gearbox is achieved.

Description

Loading machine gearbox self-lubricating device

Technical field

The utility model relates to construction machinery gear box assembly, particularly loading machine gearbox self-lubricating device.

Background technique

Domestic project machinery industry gearbox generally adopts torque-converters to add the bivariant system system of gearbox, and traditional power transmission mode is motor → torque-converters → gearbox → ransaxle.At present, a kind of use of Novel transmission mode is more and more extensive, and its transmission of power is motor → oil hydraulic pump → oil hydraulic motor → gearbox → ransaxle; Lubricant oil in this structure gearbox is without the outer cooling circulatory system, and these gearbox three shaft clutch assemblies are fixed on the housing of front and back by the cone bearing at axle two ends respectively; The problem existing is: owing to producing an outside centrifugal force in three shaft clutch assembly operation process, make gear-box lubricating oil be difficult for entering to be positioned at the friction plate assembly at three shaft clutch assemblies middle parts, like this, friction plate assembly can cause frictional force to reduce and in long-time slipping state when can not get sufficient lubrication, the final high temperature that produces, becomes gearbox potential safety hazard.

Summary of the invention

Thereby the purpose of this utility model is to provide and a kind ofly can makes under without outer cooling system prerequisite gearbox friction plate assembly obtain sufficient lubrication to avoid it to produce high temperature becoming gearbox potential safety hazard, finally reach and improve the gearbox loading machine gearbox self-lubricating device in working life.

For realizing above object, the utility model loading machine gearbox self-lubricating device comprises the semiclosed U-shaped oil groove that is comprised of front U-groove bevel and rear U-groove bevel, is located at the front lubricant pipe outside front case and is located at the rear lubricant pipe outside rear case; Gearbox three axle axle center are along being axially arranged with large through-hole, radially near friction plate assembly and bearing place, be provided with small through hole be communicated with large through-hole along three axles, and three axle two ends correspondence large through-holes are equipped with extension pipe joint and stretch out housing; Described semiclosed U-shaped oil groove is positioned at the top of three shaft clutch assemblies, and its two ends are equipped with pipe joint and stretch out housing; Front case and rear case respectively arrange two for the tapped hole of connecting tube joint and extension pipe joint; Front lubricant pipe and rear lubricant pipe upper end Tube to tube fittings, lower termination extension pipe joint, makes semiclosed U-shaped oil groove be communicated with the oil circuit of large through-hole.

The gravity that above-mentioned loading machine gearbox self-lubricating device utilizes height difference to produce is thrown to high-order lubricant oil by gear and is connected and automatically flow in clutch by oil pipe, realizes clutch lubrication, has following features:

1., before front case arranges U-groove bevel, rear case arranges rear U-groove bevel, front case and rear case in conjunction with time two U-shaped grooves form semi-enclosed oil storage space.

2., pipe joint, front lubricant pipe, extension pipe joint and rear lubricant pipe are set, front case and rear case respectively arrange two for the tapped hole of connecting tube joint and extension pipe joint, three axle axle center arrange axial large through-hole and radially little oilhole UNICOM, and the pipe joint of increase is used for being connected the oil circuit between oil groove and clutch with lubricant pipe.

Adopt above-mentioned loading machine gearbox self-lubricating structure, greatly improved the lubricating condition of clutch friction plate, improve gearbox working life, reduce Gearbox Fault, reduce enterprise's three guarantees expense, increase enterprise income.

Accompanying drawing explanation

Fig. 2 be in Fig. 1 A-A to broken section enlarged diagram.

Fig. 3 be in Fig. 1 B-B to broken section enlarged diagram.

Reference character: pipe joint 1, front lubricant pipe 2, extension pipe joint 3, front case 4, three axles 5, three shaft clutch assemblies 6, rear lubricant pipe 7, rear case 8, friction plate assembly 9, large through-hole 10, rear U-groove bevel 11, small through hole 12 and front U-groove bevel 13.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model loading machine gearbox self-lubricating device is described in further detail.

The loading machine gearbox of the utility model shown in Fig. 1～Fig. 3 self-lubricating device comprises the semiclosed U-shaped oil groove that is comprised of front U-groove bevel 13 and rear U-groove bevel 11, is located at the front lubricant pipe 2 outside front case 4 and is located at the rear lubricant pipe 7 outside rear case 8; Three axle 5 axle center are along the large through-hole 10 that is axially arranged with aperture φ 36, the small through hole 12 that is radially provided with aperture φ 10 near friction plate assembly 9 and bearing place along three axles 5 is communicated with large through-hole 10, and three axle 5 two ends correspondence large through-holes 10 are equipped with extension pipe joint 3 and stretch out housing; Described semiclosed U-shaped oil groove is positioned at the top of three shaft clutch assemblies 6, and its two ends are equipped with pipe joint 1 and stretch out housing; Front case and rear case respectively arrange two for the M18 tapped hole of connecting tube joint 1 and extension pipe joint 3; Front lubricant pipe 2 and rear lubricant pipe 7 upper end Tube to tube fittingss 1, lower termination extension pipe joint 3, makes semiclosed U-shaped oil groove be communicated with the oil circuit of large through-hole 10.

During work, because gear rotation is thrown to by the lubricant oil in casing the semiclosed U-shaped oil groove positions in a high position being comprised of front U-groove bevel 13 and rear U-groove bevel 11, this lubricant oil arrives respectively three shaft clutch assembly 6 rear and front ends by front lubricant pipe 2 and rear lubricant pipe 7, flow into after φ 36 large through-holes 10 of three axles 5, from the small through hole 12 of φ 10 radially, arrive clutch friction chip modules 9 again, friction plate assembly is lubricated fully, reach reduction TOT Transmission Oil Temperature, improve the friction plate object in working life.
