Description

Prevent the clutch of shaft end string oil

Technical field

The utility model relates to Clutch Technology field, especially a kind of clutch that can prevent shaft end string oil.

Background technique

Clutch is one of most important component of speed changer, by the separation of hydraulic controlled clutch and is implemented in combination with each shelves The conversion of position, simple, convenient, use flexibly, thus be widely used in all kinds of speed changer structures.Traditional loading machine The general not set oily structure of anti-string in the shaft end of the double clutch construction of fixed axle gearbox can if shaft end sealing ring has leakage It leaks in another clutch oil duct, to cause to store up oil, larger when revealing, oil pressure can cause the clutch plunger to act, and make Interfere at clutch, seriously will lead to clutch burn, gearbox cisco unity malfunction.A kind of existing Patent No. 201020684700.4, entitled " the pressure oil seal mechanism of double clutch construction ", the shaft end of the double clutch is provided with anti- The oily structure of string: the oil leab axially opened up among an aperture and axis is provided between two sealing rings on the axis of clutch It is connected, the oil liquid of sealing ring leakage flows into oil leab, but there are certain defects for the structure, reveal because sealing ring exists, lubrication Oil also has certain pressure, and oil liquid inversely can mutually flow, i.e., lubricating oil may also can leak to gear oil duct, to cannot rise Effect or the oily effect of anti-string to anti-string oil are not apparent.

Utility model content

The purpose of the utility model is to provide a kind of clutches for preventing shaft end string oil, and this clutch can solve existing The unconspicuous problem of the oily effect of the anti-string in double clutch shaft end.

To solve the above-mentioned problems, the technical solution adopted in the utility model is: this clutch for preventing shaft end string oil Including the oil distributing cover for the intracorporal gear axis of case being arranged in He being mounted on the cabinet side, opened on the gear axis outer wall along axial direction Lead to oil groove equipped at least two gears, is respectively set between the gear axis and oil distributing cover in the both sides that the gear leads to oil groove There is sealing ring, drain pan is provided in the axial direction on the gear axis, the drain pan is set to two adjacent gears Between logical oil groove, the gear, which leads between oil groove and the drain pan, is provided with the sealing ring；It is offered on the oil distributing cover One end of oil leak hole, the oil leak hole is connected to drain pan, and the other end is connected with the inner cavity of cabinet.

In the technical solution of the above-mentioned clutch for preventing shaft end string oil, more specific technical solution be may also is that

The oil leak hole is made of radial hole and axial hole, and the radial hole is the through-hole for penetrating the oil distributing cover wall body, The outer end of the radial hole is equipped with plug.

Further, the aperture of the radial hole is more than or equal to the width of the drain pan.

Further, the drain pan is centrally located leads between oil groove in the two neighboring gear.

Further, lead between oil groove on the gear axis in the drain pan and the gear and offer described in accommodating The rounding radii of the seal groove of sealing ring, the sealing groove edge is less than or equal to 0.2mm.

Further, the seal groove is more than or equal to 2.5mm to the distance that the drain pan, the gear lead to oil groove.

By adopting the above-described technical solution, the utility model has the following beneficial effects: compared with prior art

1, lead between oil groove on gear axis in two gears and drain pan is set, and lead between oil groove in drain pan and gear Sealing ring is set, the oil leak hole of connection drain pan and cabinets cavity is opened up on oil distributing cover, is revealed as sealing ring exists, oil liquid can It is smooth, quickly return to bottom shell, thus avoid shaft end string oil, it is simple and reliable for structure；

2, oil leak hole is made of radial through-hole and axial hole, easy to process, simple, effective；

3, the aperture of the radial hole of oil leak hole is more than or equal to the width of drain pan, it can be ensured that the oil of leakage is smooth, quick Return to bottom shell；

4, sealing groove edge rounded corner can avoid scratching sealing ring, and the restriction of rounding radii can reduce leakage again；

5, seal groove can ensure that the intensity of rib to the determination that drain pan, gear lead to oil groove, avoids collapsing slot and causes leakage, string Oil.

Fig. 3 is the structural schematic diagram of oil distributing cover.

Specific embodiment

The utility model is described in further detail for embodiment with reference to the accompanying drawing:

Fig. 1 and the clutch shown in Fig. 2 for preventing shaft end string oil are by cabinet 1, oil distributing cover 2, gear axis 3, sealing ring 4, spiral shell The parts such as bolt 6, bearing 7 composition, oil distributing cover 2 are connected in 1 side of cabinet by bolt 6, and gear axis 3 is supported on case by bearing 7 It is circumferentially opened up in body 1, on gear axis 3 there are two the logical oil groove 3-1 of gear, the both sides that each gear leads to oil groove 3-1 is respectively arranged with It is embedded with sealing ring 4 in seal groove 3-2, seal groove 3-2, is separated by the sealing ring 4 on gear axis 3 from oil distributing cover 2 different Gear leads to oil groove 3-1, reaches the effect with oil.As shown in Fig. 2, being provided in the axial direction with drain pan 3-3, draining on gear axis 3 Slot 3-3 is centrally located to be led between oil groove 3-1 in two gears, is offered between drain pan 3-3 and the logical oil groove 3-1 of each gear close The rounding radii at the edge sealing groove 3-2, seal groove 3-2 is less than or equal to 0.2mm, the logical oil of seal groove 3-2 to drain pan 3-3, gear The distance of slot 3-1 is more than or equal to 2.5mm, and the wall thickness between slot can be prevented excessively thin and crumbled.As shown in figure 3, being opened up on oil distributing cover 2 There is oil leak hole 2-1, one end of oil leak hole 2-1 is connected to the drain pan 3-3 on gear axis 3, the inner cavity 1-1 of the other end and cabinet 1 It is connected.For the ease of processing, the oil leak hole 2-1 of the present embodiment is made of radial hole 2-11 and axial hole 2-12, radial hole 2- 11 be the through-hole for penetrating 2 wall body of oil distributing cover, and the outer end of radial hole 2-11 is equipped with plug 5, and the aperture radial hole 2-11 is more than or equal to The outer rim of the width of drain pan 3-3, radial hole 2-11 is overlapped or intersects with the two edges drain pan 3-3；Axial hole 2-12 and radial direction The perpendicular formation cross bore of hole 2-11, one end of axial hole 2-12 are connected with radial hole 2-11, and the other end extends to oil distributing cover 2 Inner face is connected with the inner cavity 1-1 of cabinet 1.

Originally the clutch for preventing shaft end string oil, since pressure is low in cabinet 1, if sealing ring 5 has the case where leakage, shelves The oil liquid of the logical oil groove 3-1 internal leakage in position can by drain pan 3-3 and oil leak hole 2-1 is smooth, quickly returns to bottom shell, thus Shaft end string oil is avoided, it is simple and reliable for structure, and oil leak hole 2-1 can be easy to process, simple, have directly on casting oil distributing cover 2 Effect.
