Abstract
The utility model discloses an axial locating structure of an electromotor shaft, which is provided with two deep groove ball bearings as well as the inner covers and the outer covers of fastening bearings; wherein the inner covers and the outer covers of the bearings are matched with the deep groove ball bearings; and movement clearances are arranged between the outer rings of the deep groove ball bearings and the inner covers and the outer covers of the bearings. The axial locating structure of the electromotor shaft causes the front bearing and the rear bearing of an electromotor to be uniformly strained, and avoids the damage phenomena of the bearings, such as rapid temperature rise in short time, shaft suspension and falling into pieces and the like; moreover, the axial bearing capacity is enhanced by one time, and the electromotor runs stably, thereby prolonging the service lives of the bearings and also prolonging the service life of the electromotor.
Description
Technical field
The utility model belongs to the motor technology field, is specifically related to a kind of axial positioning structure of motor reel.
Background technology
Deep groove ball bearing is because of its axial load that can bear certain radial load and two directions, and it is little that it has moment of friction, low noise, low vibration, characteristics such as rotary speed height, extremely electromechanics trade favor.All use the motor of deep groove ball bearing configuration for the motor two ends, the conventional arrangement method is the bearing axial restraint that is configured in the electric motor fan end, the effect of rigid bearing is that moving axially of axle is limited in certain scope, stuck by bearing exterior and interior cover seam bearing top circle, and the shaft extension end adopts the bearing that moves about that can axially move freely.Move about bearing when using cylinder roller bearing or rolling bearing, and Internal and external cycle is separable and can move, but the Internal and external cycle of deep groove ball bearing is inseparable.If deep groove ball bearing as the bearing that moves about, the factor such as expand with heat and contract with cold of the axle that need consider the shaft extension end not have the machining tolerance accumulation of preload and parts and variations in temperature and produce, so this configuration can make the bearings at both ends discontinuity, under some unpredictable axial load effects, bearing temperature within a short period of time is raise, phenomenon such as produce seize, fall apart.
The utility model content
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of two ends all to adopt the axial positioning structure of the motor reel of deep groove ball bearing support, and it is stressed evenly to have the motor front and back bearings, and the life-span of bearing is long, motor rotation is steady, has improved the useful life of motor.
For achieving the above object, the technical solution adopted in the utility model is: the axial positioning structure of this motor reel has inner cap, the enclosing cover of two deep groove ball bearings and fastening bearing, it is characterized in that: the inner cap of described bearing, enclosing cover and be provided with the gap of moving about during deep groove ball bearing cooperates between the outer ring of deep groove ball bearing and internal bearing cover, enclosing cover.
Inner cap, the enclosing cover of the bearing of described motor shaft extension end and between the inner cap of the outer ring of deep groove ball bearing and bearing, enclosing cover, be provided with the gap of moving about during deep groove ball bearing cooperates.
The inner cap of the bearing of described electric motor fan end, enclosing cover and between the inner cap of the outer ring of deep groove ball bearing and bearing, enclosing cover, be provided with the gap of moving about during deep groove ball bearing cooperates.
Adopt the beneficial effect of technique scheme: this motor reel axial positioning structure is the structure of all not locking to motor shaft extension end and fan end bearings at both ends, and then within the limits prescribed the restriction of motor shifting amount, to all staying certain gap of moving about between front and back bearings and its bearing exterior and interior cover, make the motor front and back bearings stressed evenly, avoid bearing at short notice temperature sharply increase, burning in of bearing, fall apart etc. and to damage phenomenon, and axial bearing capacity can double, motor rotation is steady, thereby improved the life-span of bearing, also improved the useful life of motor.This structure has obtained practice in motor production, serious seize do not occur in tentative and later production process, the phenomenon of falling apart, and result of use is good.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 has the structural representation in the gap of moving about for motor shaft extension end bearing.
Fig. 2 motor shaft two ends all have the structural representation in the gap of moving about.
Embodiment
Motor reel axial positioning structure as shown in Figure 1, have two deep groove ball bearings 7,9, deep groove ball bearing 7,9 is sleeved on the motor reel 2, motor reel 2 has shaft extension end 1 and fan end 4, motor reel is installed in the bearing chamber of End cover for motor 3 by bearing, the outer ring of deep groove ball bearing 7 is a contact matching with inner cap 6, enclosing cover 5 respectively, and deep groove ball bearing 7 is fixed by placing restrictions on property.The outer ring of deep groove ball bearing 9 is provided with move about gap T1, T2 respectively and between the inner cap 8, enclosing cover 10.As shown in Figure 2 as further improving, the two-way bearing arrangement that moves about that motor shaft extension end and fan end bearings at both ends are not all locked, the outer ring of the deep groove ball bearing 7 of electrical motor fan end is provided with move about gap T1, T2 respectively and between the inner cap 6, enclosing cover 5.In use the motor front and back bearings is stressed evenly, avoid bearing at short notice temperature sharply increase, burning in of bearing, fall apart etc. damages phenomenon, and axial bearing capacity can double, motor rotation is steady, has improved the life-span of bearing.
