The utility model discloses a two angular contact bearings, its characterized in that, two angular contact bearing installs on the axle sleeve back to through the round nut with the axle sleeve fastening, angular contact bearing with axle sleeve integral mounting is on the bearing body, there is adjusting nut axle sleeve tip through the screw connection, there is the bearing gland through bolted connection on the bearing body, the bearing gland with equal detachably is provided with the direct type pressure on the bearing body and annotates the oil cup. The utility model discloses can make things convenient for the adjustment of rotor axial position, need not just can overhaul very convenience with pump disintegration when overhauing simultaneously.
Description
Technical Field
The utility model belongs to the technical field of the industrial pump, specifically relate to a grease lubrication bearing body for vertical major axis submerged pump.
Background
The pump shaft for the vertical long-shaft submerged pump at present is usually provided with a bearing which is directly arranged on the shaft, the structure is very troublesome when the position of a rotor needs to be adjusted or a bearing body needs to be overhauled, the pump is usually required to be disassembled, and great trouble is brought to overhauling work.
Disclosure of Invention
Aiming at the problems, the utility model makes up the defects of the prior art and provides a grease lubrication bearing body for a vertical long-shaft submerged pump; the utility model discloses can make things convenient for the adjustment of rotor axial position, need not just can overhaul very convenience with pump disintegration when overhauing simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme.
The utility model provides a grease lubrication bearing body for vertical major axis submerged pump, including two angular contact bearing, its characterized in that, two angular contact bearing installs on the axle sleeve back to through round nut with the axle sleeve fastening, angular contact bearing with axle sleeve integral mounting is on the bearing body, the axle sleeve tip has adjusting nut through the screw connection, there is the bearing gland through bolted connection on the bearing body, the bearing gland with equal detachably is provided with direct formula pressure injection oil cup on the bearing body.
The beneficial effects of the utility model.
The utility model can be integrally installed outside the pump shaft after the installation and can be matched with the pump shaft to directly adjust the axial position of the rotor shaft through the adjusting nut, which is more convenient; in addition, when the corresponding parts need to be overhauled, the whole part is only required to be disassembled, the pump does not need to be disassembled, and convenience is brought to overhauling work.
Drawings
In order to make the technical problem, technical scheme and beneficial effect that the utility model solved more clearly understand, it is right to combine the attached drawing and detailed description mode below the utility model discloses further detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Fig. 1 is a sectional view of the structure of the present invention.
The labels in the figure are: the bearing comprises a bearing gland 1, an adjusting nut 2, a straight-through type pressure filling oil cup 3, a bearing body 4, a round nut 5, a shaft sleeve 6, an angular contact bearing 7, a bolt 8 and a screw 9.
Detailed Description
The grease lubrication bearing body for the vertical long-shaft submerged pump comprises two angular contact bearings 7, wherein the two angular contact bearings 7 are arranged on a shaft sleeve 6 in a back-to-back mode and are fastened with the shaft sleeve 6 through a round nut 5, the angular contact bearings 7 and the shaft sleeve 6 are integrally arranged on a bearing body 4, the angular contact bearings 7, the shaft sleeve 6 and the bearing body 4 are integrally arranged on a pump shaft, and the shaft sleeve 6 is in clearance fit with the pump shaft. The bearing body 4 is fixed to the bearing body support of the pump by means of bolts 8.
The end part of the shaft sleeve 6 is connected with an adjusting nut 2 through a screw 9, the screw 9 is unscrewed when the axial position of the rotor needs to be adjusted, the axial position of the rotor is adjusted through the screw thread on the pump shaft by using the adjusting nut 2, and the adjusted rotor is connected on the shaft sleeve 6 through the screw 9.
The bearing body 4 is connected with a bearing gland 1 through a bolt 8, and the bearing gland 1 and the bearing body 4 are both detachably provided with a straight-through type pressure injection oil cup 3.
When needs overhaul bearing body 4 part, screw down bolt 8 earlier, take off bearing gland 1 again, screw down bolt 8, pull down adjusting nut 2, pull down the bolt 8 of connecting bearing body 4 and bearing body support at last, can pull down bearing body 4 part wholly and overhaul convenient and fast.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
