Detailed Description

As shown in fig. 1 and 2, the device for preventing the high-speed shaft of the speed reducer and the motor from being worn and leaked includes an annular suction cup 8 and a neck sleeve 4, wherein a suction nozzle 1 is arranged on the annular suction cup 8, the top of the annular suction cup 8 is hermetically connected with the outer wall of the neck sleeve 4 through a connecting part 5, the neck sleeve 4 is coaxial with the annular suction cup 8, and a sealing part 2 is arranged in the neck sleeve 4. When the device is used, the device is sleeved on a high-speed shaft, the sealing element 2 and the high-speed shaft form sealing, and the annular sucker 8 is adsorbed on the outer surface of the end cover of the high-speed shaft with oil leakage through the exhaust nozzle 1. Because of the sealing connection of the connecting part 5 and the sealing element 2 in the neck sleeve 4, a closed space is formed between the annular inner side of the annular sucker 8 and the neck sleeve 4, lubricating oil flowing out from between the high-speed shaft and the end cover of the high-speed shaft is stored in the closed space, and the oil does not overflow due to the integral sealing performance of the device after reaching a certain degree, so that the temporary plugging of oil leakage power equipment is completed.

It should be noted that the sealing element 2 may use a framework oil seal or an O-ring, as the case may be, and the collar 4 and the annular suction cup 8 may be designed as an integrally formed rubber product, and at this time, in order to ensure a reliable connection between the sealing element 2 and the collar 4, the collar 4 may be injection-molded by wrapping the steel sleeve 3 therein, so as to facilitate the installation and positioning of the sealing element 2.

In the device, a support 6 is arranged on the top surface inside the annular suction cup 8, a contact plate 7 is arranged at the tail end of the support 6, and the bottom surface of the contact plate 7 is flush with the bottom surface of the annular suction cup 8. The reason is that certain torsional friction exists between high-speed shaft and sealing member 2 like this to produce torsional force to annular sucking disc 8, long-time operation probably can make annular sucking disc 8 produce certain rotation, and the sucking disc rotates and causes gas leakage easily and finally leads to sealed not tight. After the annular sucking disc 8 generates pressure, the top wall of the sucking disc generates downward pressure on the contact plate 7 through the strut 6, so that strong friction force is generated between the contact plate 7 and the end cover of the high-speed shaft, and the annular sucking disc 8 is prevented from rotating. In particular, a strip 9 can be provided on the underside of the contact plate 7, the strip 9 being oriented towards the center of the ring-shaped suction cup 8. Such a stripe 9 can further enhance the friction force for preventing rotation, and ensure the sealing performance of the device.

In addition, as shown in fig. 2, the number of the contact plates 7 of the present embodiment is 8, and the contact plates are distributed around the center of the ring-shaped suction cup 8. In order to make the friction force for preventing rotation more uniform, the contact plates 7 should be distributed circumferentially with the center of the ring-shaped suction cup 8 as the center of the circle, but the whole body is not necessary to be made into a ring shape, and making the contact plates 7 and the support 6 separately simplifies the manufacturing process and saves materials.

In addition, as seen from a section passing through the axis of the neck collar 4, that is, as seen from fig. 1, the connecting portion 5 of the present embodiment is in an inwardly concave arc shape, and the connecting portion 5 in this shape makes the whole device have a form with a thick root and a thin top, so that the neck collar 4 at the top of the device can swing to a certain extent while the ring-shaped suction cup 8 provides strong suction and is stable. The reason for this is that although the neck collar 4 is coaxial with the annular sucker 8, the annular sucker 8 inevitably generates a certain non-concentricity with the high-speed shaft when the device is installed, and under the driving of the rotating high-speed shaft, in order to prevent the annular sucker 8 from being driven to move and the sealing is not tight, the neck collar 4 and the annular sucker 8 need to be allowed to swing to a certain extent, and the device cannot be sealed, so the connecting part 5 with the shape can well solve the above problems.
