Abstract
The utility model relates to an oil recovering device for a bearing seat; wherein, a horizontal main shaft (11) penetrates through a closed oil cavity (7) which is arranged on the bearing seat and is connected with the port of an oil cavity casing body (13) through a support of a bearing (6); a press cover (5), which is connected by sealing with the port of the oil cavity casing body, is arranged at the outer side of the bearing; the main shaft penetrates by sliding and matching through the press cover through a seal part (4). The utility model is characterized in that: an oil collecting cover (2), which covers the connection part of the main shaft and the outer wall surface of the press cover, is fixed at outer wall surface of the press cover (5); certain distance is arranged between the inner wall of the oil collecting cover and the main shaft and between the front port of the oil collecting cover and the outer wall surface of the press cover; seal connection is made between the back port of the oil collection cover and the press cover (5); a reflux port (3), which is communicated with the oil cavity (7), is arranged at the bottom part of inner cavity for the oil collection cover and is higher than the oil level inside the oil cavity. The utility model has the advantages of solving well the oil leakage problem for the bearing seat of the horizontal high speed rotary equipment, saving oil consumption, lowering environmental pollution, lowering equipment failure caused by oil leakage, and avoiding fire accident caused by oil leakage under high temperature status.
Description
Technical field
The utility model is a kind of leakage of oil recovering device that is installed in the bearing support at equipment running shaft positions such as blower fan, water pump.
Background technique
When the bearing support that is installed in equipment running shaft positions such as the horizontal blower fan that is connected with electric-motor-driving, water pump, cycloid pin motor, stepless speed regulation motor ripple case need move under high temperature, fast state, be everlasting and be provided with the oil pocket that oiling agent is provided for bearing in the bearing support, its shaft end seal parts adopt outside framework oil seal, V-type oil sealing, T type oil sealing, wool felt, graphite oil sealing, wick etc. more, and this class sealed member all can not effect a radical cure the leakage of oil problem of equipment under high temperature, high speed operation state.
Summary of the invention
The technical problems to be solved in the utility model provides the bearing support leakage of oil recovering device of the above-mentioned horizontal equipment oil leakage problem of the fine solution of a kind of energy.
The technological scheme that addresses the above problem is (referring to implementing illustration): the utility model level to main shaft (11) pass the oil closed cavity (7) that is provided with on the bearing support, and be connected with oil pocket housing (13) port by bearing (6) lining, the bearing outside is provided with the gland (5) that is tightly connected with oil pocket housing port, main shaft passes gland by Sealing (4) with being slidingly matched, it is characterized in that: on gland (5) outer wall, be fixed with the oil pooling hood (2) that covers main shaft and gland outer wall commissure position, between oil pooling hood madial wall and the main shaft, all draw back certain distance between oil pooling hood front port and the gland outer wall, oil pooling hood rear port and gland (5) are tightly connected, the oil pooling hood intracavity bottom is provided with the refluxing opening (3) that is communicated with oil pocket (7), and refluxing opening is higher than the pasta in the oil pocket.
Adopt the equipment such as horizontal blower fan, water pump of this device on-stream, when the oil in the bearing support oil pocket along the main shaft of high speed rotating when Sealing spills, can under action of centrifugal force, be thrown on the madial wall of oil pooling hood, and flow out, flow back to oil pocket from the refluxing opening of bottom.
The leakage of oil problem of the fine solution horizontal high-speed rotating equipment bearing support of the utility model energy, save oil consumption, reduce environmental pollution, and can reduce the rate of occurrence of equipment failure that causes because of leakage of oil, avoid the fire accident that causes because of leakage of oil under the condition of high temperature, reduce the engineering time and the maintenance expenses of equipment.
