Abstract
The utility model relates to a seal device of an oil pump shaft of a driving detection wheel of a rectification machine. The seal device comprises three speaking trumpet shaped inner dust-proof shield, middle dust-proof shield and outer dust-proof shield, wherein he there dust-proof shields are sequentially jacketed through using the shaft center line of the oil pump shaft as the installation center, the bellmouthings of the three dust-proof covers are sequentially crossed and opposite, a gap is left between the bellmouthings of two adjacent dust-proof shields, the bottom edges of the outer dust-proof shield and the inner dust-proof shield are fixedly mounted with the oil pump cover board, and gaps are left between the bellmouthing of the middle dust-proof shield and the oil pump cover board. The seal device has compact structure and excellent sealing performance, is a seal structure designed aiming at the hostile environment of mining areas, has excellent performance in the dust-proof and water-proof aspects, and has excellent protection functions to improving the service span of the oil pump and the stability of the equipment.
Description
Technical field
The utility model relates to the passive hydraulic deviation correcting device of belt conveyer, and wheel oil pump shaft seal is driven in particularly a kind of correction machine examination.
Background technology
The passive hydraulic deviation correcting device is used for the belt deviation of belt conveyer to be corrected, and is widely used in the colliery, the harbour, and Metallurgical Factories etc. are because its special environment for use generally is in many dust, in the moist environment.It is that the wheel direct connection is driven in oil pump shaft and inspection that the structure that generally adopts of installation that wheel and inspection drive the wheel oil pump is driven in the inspection of existing passive Hydraulic Deviation-correcting Device, inspection is driven and is had axis hole and keyway on the wheel, fix by jump ring, oil pump shaft and inspection are driven does not have other sealing arrangement between the wheel, oil pump shaft is exposed in the middle of environment.When being applied to occasion such as mine, dust or mud are easy to drive wheel and flow into the oil pump bearing along inspection, cause sealing member to damage, the bearing corrosion, and wearing and tearing because of the oil pump fault causes equipment failure, and may cause industrial accident to take place.
Summary of the invention
For overcoming the shortcoming of prior art, goal of the invention of the present utility model provides a kind of correction machine examination and drives wheel oil pump shaft seal, and this device is arranged on inspection and drives wheel and drive between the wheel oil pump with inspection, can drive the wheel oil pump shaft to inspection and seal.The sealing device can be applied to various harsies environment, and sealing effectiveness is good.
The purpose of this utility model is achieved in that a kind of correction machine examination drives wheel oil pump shaft seal, described sealing arrangement is formed by being arranged on interior dust boot, middle dust boot, the outer dust boot of three loudspeaker tubulars that inspection drives between wheel and the oil pump, described three dust boots are mounting center line order suit with the axial line of oil pump shaft, and the exit skirt of three dust boots intersects in proper order and leaves the gap between the exit skirt of relative, adjacent dust boot; The root edge of described outer dust boot, interior dust boot and the fixed installation of oil pump cover plate, the exit skirt of described outer dust boot, interior dust boot and inspection are driven and are left the gap between the wheel; The wheel fixed installation is driven in the root edge of dust boot and inspection in described, leaves the gap between the exit skirt of described middle dust boot and the oil pump cover plate.
The root edge of described outer dust boot and interior dust boot is installed on the oil pump cover plate by screw retention; The root edge of dust boot has pin in described, and this pin drives the pin-and-hole interference installation that wheel is provided with inspection.
The beneficial effect that the utility model produces is: the utility model compact conformation, small and exquisite exquisiteness is made and is consumed few, the good seal performance of material, is at the designed hermetically-sealed construction of harsies environment such as mining area.Possessing excellent properties aspect the oil pump dustproof and waterproof, the life-span of improving oil pump and the stability of equipment are being played a very good protection.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment:
Referring to Fig. 1, in the present embodiment, the correction machine examination is driven wheel oil pump shaft seal and is driven interior dust boot 6, middle dust boot 5, the outer dust boot 4 of three loudspeaker tubulars between wheel 1 and the oil pump 8 and form by being arranged on inspection, inspection is driven to take turns and is captiveed joint with oil pump shaft 9 usefulness bolts 2, three dust boots are mounting center line order suit with the axial line of oil pump shaft, and the exit skirt of three dust boots intersects in proper order and leaves the gap between the exit skirt of relative, adjacent dust boot; The root edge of outer dust boot, interior dust boot and the fixed installation of oil pump cover plate, the exit skirt of outer dust boot, interior dust boot and inspection are driven and are left the gap between the wheel; The wheel fixed installation is driven in the root edge of middle dust boot and inspection, leaves the gap between the exit skirt of middle dust boot and the oil pump cover plate.
In the present embodiment, the root edge of outer dust boot and interior dust boot is fixedly mounted on the oil pump cover plate by screw 7; The root edge of middle dust boot has pin 3, and this pin drives the pin-and-hole interference installation that wheel is provided with inspection.
Sealing function of the present utility model are: outer dust boot of the present utility model and interior dust boot are to be fixedly mounted on the oil pump cover plate, dust boot is fixedly mounted on to examine and drives on the wheel in of the present utility model, drive wheel with inspection and rotate, promptly in dust boot rotate between dust boot and the interior dust boot outside.Outside of the present utility model under the protection of dust boot; most of dust or mud can be blocked on the outside of outer dust boot; a spot of dust and mud may along the exit skirt of outer dust boot and inspection drive the gap of leaving between the wheel enter outside between dust boot and the middle dust boot; this part foreign matter under the effect of gravity, can along middle dust boot below get rid of.If have the dust of less amount or mud along the exit skirt of middle dust boot and inspection drive the gap of leaving between the wheel continue to enter between dust boot and the interior dust boot; then triple just innermost interior dust boots will play a protective role; under identical action principle, make foreign matter below get rid of.
