The technical field is as follows:

the invention relates to the field of hardware processing machinery, in particular to a device for preventing shaft oil leakage, splashing and splashing.

Background art:

in order to reduce temperature and reduce friction force, as shown in fig. 1, although sealing rings are usually installed at two ends of the shaft sleeve 2 in actual work, oil still seeps out from a joint 13 between the shaft 1 and the shaft sleeve 2, and the leaked oil is thrown and splashed by a part of rapidly rotating shafts, particularly when the sealing rings are worn, and the direction of the thrown and splashed oil points is not uniform, so that oil stains on the ground of a working environment, belt pulleys of a machine, belts and the like, and sometimes the oil stains on workers are caused.

Not only does this cause pollution of the workshop environment, but oil spots splashed on the belt can also cause problems of accelerated belt aging.

The invention content is as follows:

in order to solve the problems, the invention is not to develop a device for preventing the shaft from oil leakage and splashing. The device is characterized by comprising a backing ring, a shielding disc, a locking ring and the locking ring, and the specific technical scheme is as follows:

a device for preventing shaft oil leakage, throwing and splashing comprises a backing ring sleeved on a rotating shaft, a shielding disc, a locking ring and a residual oil cover sleeved on the locking ring or a belt pulley and connected with a machine body.

The backing ring is not provided with the boss configuration to the pivot of some lathe, uses when using in the pivot that does not set up the boss the device need connect and use this part, its purpose be in one side fixed shelter from the dish, do not let and shelter from the dish and the contact of axle sleeve to the during operation shelters from the dish and produces the motion friction with the motionless axle sleeve along with axle pivoted and is damaged, and the internal diameter of backing ring corresponds with the external diameter at pivot installation position, can make the backing ring cover in the pivot.

The shielding plate is in a dish shape, a through hole with the same diameter as that of the corresponding part of the rotating shaft is arranged in the center of the bottom of the plate, and the edge of the plate is an inclined plane extending from the bottom to the top.

The locking ring is provided with a countersunk screw hole and a countersunk screw, and is a component which is matched with the other side of the shielding disc and is selectively used aiming at the condition that a belt pulley is not arranged at one end of a machine tool rotating shaft or the other side of the shielding disc can not be fixed by the arranged belt pulley.

The bottom of the residual oil cover is provided with a container part, the inner bottom wall of the container part inclines to one side, and a through pipe leading to the outside is arranged on the side with low fall;

the rear surface wall of the residual oil cover is provided with a through hole, and the upper part of the front surface wall corresponding to the rear wall surface is provided with an opening, so that the shielding plate can be placed into the inner space of the residual oil cover at the opening and positioned above the container part.

And connecting parts are arranged on the surface walls of the two sides of the residual oil cover, and connecting holes are arranged on the connecting parts.

The beneficial effects of this technical scheme are: through sheltering from of sheltering from the dish, make to be got rid of the oil that spatters the oil drop stop on sheltering from the internal surface of dish along the dish of slope drip in the container portion that remains the oil blanket, not only solved the pivot that hardware processing machinery exists and got rid of oily problem, can also collect the oil drop that spatters the departure and get up recycling.

the specific implementation mode is as follows:

the device for preventing the shaft from oil leakage and splashing is further explained by combining the attached drawing.

Referring to fig. 2, as shown in the figure, the device for preventing the shaft from oil leakage and splashing comprises a backing ring 18 sleeved on the rotating shaft 1, a shielding disc 3, a locking ring 16, and a residual oil cover 4 sleeved on the locking ring 16 or a belt pulley and connected with a machine body.

Referring to fig. 1 and 2, as shown in the drawings, the backing ring 18 is configured for a spindle 1 of some machine tools without a boss 14, and when the device is used on a spindle without a boss, the device needs to be connected to use the component, which is intended to fix the shielding plate 3 on one side, so that the shielding plate 3 does not contact with the spindle sleeve 2, and the shielding plate 3 rotating with the spindle during operation generates movement friction with the stationary spindle sleeve 2 and is damaged, and the inner diameter of the backing ring 18 corresponds to the outer diameter of the mounting portion of the spindle 1, so that the backing ring 18 can be sleeved on the spindle 1, and thus the component is selectively used.

The shielding plate 3 is in a dish shape, the center of the bottom of the plate is provided with a through hole 8 with the same diameter as the corresponding part of the rotating shaft 1, and the edge 7 of the plate is an inclined plane extending from the bottom to the outside.

The locking ring 16 is provided with a countersunk screw hole 19 and a countersunk screw 17, and is a matched part which is not provided with a belt pulley at one end of a rotating shaft of the machine tool or cannot be used for fixing the other side of the shielding disc by using the belt pulley, so that the part is selectively used.

The bottom of the residual oil cover 4 is provided with a container part 9, the inner bottom wall of the container part 9 inclines to one side, and a through pipe 12 leading to the outside is arranged on the side with low fall;

the rear surface wall of the residual oil cover 4 is provided with a through hole 8, the upper part of the front surface wall corresponding to the rear wall surface is provided with an opening, and the shielding plate can be placed into the inner space of the residual oil cover at the opening and is positioned above the container part.

The two side surface walls of the residual oil cover are provided with a connection part 10, and the connection part is provided with a connection hole 11;

embodiment 1, referring to fig. 1, 2, 3 and 4, as shown in the figure, the embodiment is to use the technical solution on the machine shown in fig. 1, and the machine shown in fig. 1 is characterized in that: when the device of the scheme is used on the rotating shaft 1, the lug boss 14 and the belt pulley 5 are arranged on the rotating shaft 1, the device can be used without using the backing ring 18 and the locking ring 16 shown in fig. 2, when the shielding disc 3 is sleeved on the rotating shaft 1, the shielding disc is clamped between the connecting part of the lug boss 14 and the belt pulley 5, and leaves a proper space with the shaft sleeve 2, when the shielding disc rotates along with the rotating shaft, the shielding disc 3 does not generate movement friction with the shaft sleeve to damage the shielding disc, the residual oil cover 4 is sleeved on the connecting part of the belt pulley 5 through the through hole 8 on the residual oil cover and is connected on the machine body of the machine through the connection 10 on the residual oil cover, the shielding disc 3 is positioned in the inner cavity of the residual oil cover 4 and above the container part 9, when oil drops seep out at the interface 13 between the shaft sleeve 2 and the rotating shaft 1, the oil drops along the shaft surface if the oil drops into the container part 9 if the oil drops are not thrown off, the shielding disc 3 and drops into the container part 9 along the disc edge 7, and the research and development purposes of the invention are achieved.

Embodiment 2, with reference to fig. 2 and 5, as shown, this embodiment is characterized in that: the rotary shaft 1 is not provided with the boss 14 and the belt pulley 5, so when the device of the scheme is used on the rotary shaft, the shielding disc 3 is clamped by the cushion ring 18 and the locking ring 16 which are selectively used, and the locking ring 16 is fixed on the rotary shaft 1 through the countersunk head screw 17, so that the shielding disc 3 can obtain the same working environment as that of the embodiment 1.
