Abstract
A three-phase asynchronous motor for vertical type pipeline circulating pump comprises a casing and a stator in the inside of the casing, wherein the lower end of the casing is provided with a flange, the upper end of the casing is provided with an end cap, the inner bore of the flange is provided with a driving end bearing, the inner bore of the end cap is provided with a non-driving end bearing, a bearing cap is equipped above the non-driving end bearing, a rotating shaft is installed through the non-driving end bearing and the driving end bearing, the rotating shaft is provided with a rotor matched with the stator, and the driving end bearing is a single row angular contact ball bearing; the central bore of the flange is directly sleeved on the rotating shaft; and a preload spring is arranged between the non-driving end bearing and the bearing cap. The motor bearing system is easy to lubricate, the axial bearing capacity is stronger, the operation is stable, brisk, and low in noise, and the average service life of the bearing of the motor system is improved.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of riser circulating pump threephase asynchronous.
Background technology
Existing riser circulating pump is that a vertical casing is arranged with the threephase asynchronous structure, be provided with stator in the casing inboard, lower end at casing is fixed with flange, the upper end of casing is fixed with end cap, the endoporus of flange has drive end bearing and below to be fixed with the drive end bearing lid, and there is non-driven-end bearing at the endoporus place of end cap, and the non-driven-end bearing top is provided with the non-driven-end bearing lid, by non-driven-end bearing and drive end bearing rotating shaft is installed, rotating shaft is provided with the rotor that matches with stator.Wherein drive end bearing is that two single-groove grooved place kick bearings are set up in parallel, adopt a deep groove ball bearing as floating end at anti-drive end, the motor of this structure, drive end two row bearing lubrication conditions are poor, occur often that single bearing lubrication was lost efficacy in advance and the phenomenon that causes the motor bearings system crash; The drive end bearing lid bears bigger axial force in the course of the work, and is fragile; Non-driven-end bearing lid is to the preload force deficiency of non-driven-end bearing, can't self-regulated, and noise is big during operation.
Summary of the invention
Stressed rationally, strong, the low noise riser circulating pump of the axial load bearing capacity threephase asynchronous of each parts overcame the deficiencies in the prior art when the purpose of this utility model provided a kind of simple in structure, motor operation.
Riser circulating pump threephase asynchronous of the present utility model, comprise casing, be positioned at the stator of casing inboard, lower end at casing is provided with flange, the upper end of casing is provided with end cap, and the endoporus of flange has drive end bearing, and there is non-driven-end bearing at the endoporus place of end cap, nonpowered axle holds the top and is provided with bearing cap, by non-driven-end bearing and drive end bearing rotating shaft is installed, rotating shaft is provided with the rotor that matches with stator, and described drive end bearing is single-row angular contact ball bearing; The centre bore of flange directly is sleeved in the rotating shaft; Between non-driven-end bearing and bearing cap, be provided with preloaded spring.
Riser circulating pump threephase asynchronous of the present utility model, because drive end bearing is angular contact ball bearing and single setting, make that the bearing of motor system is easily lubricated, axial carrying capacity is stronger, the brisk noise that operates steadily is lower, improve the average life span of electric motor system bearing, guaranteed the reliability service of motor whole system.The endoporus of flange directly is sleeved in the rotating shaft, make drive end bearing no longer utilize bearing cap to carry out axial restraint, ensured axial carrying and the positioning function of drive end bearing as the motor bearings system, avoided dependence to bearing cap, simplify the bearing arrangement structure, further improved axial bearing capacity.Between non-driven-end bearing and bearing cap, preloaded spring is arranged, keep the axial pre-load power of spring constantly, and can regulate voluntarily.

Embodiment
Shown in Fig. 1,2,3,4: 5 is casing, vertical setting.Stator 6 is installed in casing, the lower end bolt of casing 5 is fixedly connected with flange 2, the upper end bolt of casing 5 is fixed with end cap 8, endoporus place at flange 2 is provided with drive end bearing 1, drive end bearing 1 is single angular contact ball bearing, be provided with non-driven-end bearing 7 at the endoporus place of end cap 8 and by bearing cap 11 axial limitings, be connected for bolt between bearing cap 11 and the end cap 8.Be supported with rotating shaft 4 by drive end bearing 1 and non-driven-end bearing 7, in rotating shaft 4, be provided with the rotor 3 that matches with stator 6.The endoporus of flange 2 directly is sleeved in the rotating shaft 4, and flange 2 directly bears axial force when motor moves.Clamping has preloaded spring 9 between non-driven-end bearing 7 and bearing cap 11, to guarantee to give all the time non-driven-end bearing 7 certain preload force.Preloaded spring 9 is the circumferential groove 13 of sheet and the oriented fovea superior of endoporus one side ringwise.In the top of rotating shaft fan 10 is installed.
