Abstract
The utility model discloses a pinion shaft hole sealing structure of a ball mill, which comprises an annular oil return ring arranged inside a pinion cover (1), wherein the oil return ring comprises a fixed plate (2-1) and a baffle (2-2). The hole of a pinion shaft (5) is provided with a shaft sleeve (3) extending into the pinion cover (1), and the outer end of the shaft sleeve (3) is arranged on a bearing seat (9); and the part of the shaft sleeve (3), positioned inside the pinion cover (1), is provided with an oil return groove (10). The pinion shaft (5) is provided with an oil retaining ring (4) corresponding to the shaft sleeve (3). The utility model provides a novel reliable edge-driving pinion shaft hole sealing structure of the ball mill, which converts the traditional dynamic packing seal to the static packing seal, has excellent sealing effect and can solve the problem of leakage at the pinion shaft hole completely.
Description
Technical field
The utility model relates to a kind of grinding machine sealing, is specifically related to a kind of grinding machine small gear axis hole sealing configuration.
Background technique
The edge transmission grinding machine of Shi Yonging in the market, its small gear axis hole sealing is dynamic packing seal, promptly undertaken by the seal ring that is enclosed within on the axle, between seal ring and the axle friction is arranged, oil still can spill by the space of friction output, can not thoroughly solve this place's leakage problem, cause pebble mill small gear axis hole to be sealed to troubling the technical barrier of industry for a long time.
The model utility content
The purpose of this utility model provides a kind of pebble mill small gear axis hole sealing configuration that prevents that oil impregnate is effective.
The utility model technology is achieved through the following technical solutions:
A kind of pebble mill small gear axis hole sealing configuration is characterized in that: described sealing configuration comprises and is arranged at the oil return circle gear cover inboard, ring-type that described oil return circle comprises fixed plate and baffle plate.
In order to guarantee that oil does not drop on the pinion shaft, described pinion shaft is provided with the axle sleeve that stretches into gear cover at the axis hole place, and the outer end of described axle sleeve is arranged on the bearing support; The inside part that axle sleeve is positioned at gear cover is provided with oil-return groove.
In order to guarantee that the oil on the small gear does not outwards ooze out, described pinion shaft is provided with the flinger ring of axle sleeve correspondence.
The outside of outwards not oozing out described gear cover for the oil on the further assurance small gear is disposed with sealing seat, seal ring and gland, and gland compresses sealing seat and axle sleeve by seal ring, forms sealing state.
The utility model provides a kind of brand-new edge transmission grinding machine small gear axis hole sealing configuration reliably, changes traditional dynamic packing seal into static packing seal, and sealing effect is splendid, can thoroughly solve pinion shaft hole site leakage problem.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described:
As shown in Figure 1:
The oil return circle comprises fixed plate 2-1 and baffle plate 2-2, certainly these two parts can be an integral body, the oil return circle is welded on gear cover 1 pinion shaft 5 axis hole inboards, and the oil that flows down from gear cover 1 inwall directly flows back to fuel tank through the oil return circle, and it is not flowed on pinion shaft 5.Flinger ring 4 is installed on the pinion shaft 5, flows to oil on the axle from the pinion gear teeth ditch and is blocked by flinger ring 4 midway and directly flow back to fuel tank, no longer outflows along axle.Owing to be provided with oil return circle and flinger ring 4, guaranteed that most oil do not flow to pinion shaft 5, have significantly reduced the sealing load of axis hole.
Claims (4)
