Abstract
The utility model discloses a high-speed motor, which is provided with a rotor shaft, a front bearing, a front bearing seat, a stator, a rotor, a casing, a back bearing, a back bearing seat, a regulating spring and a back cover, wherein, the casing and the front bearing seat are provide with oil channels; the back bearing seat is provide with an oil through hole; an elastic support ring is arranged between the peripheral face of the back bearing seat and the hole wall of the casing. The utility model has the advantage of long-period fine adjustment of the coaxiality of the rotor shaft, long service life of the motor and low cost.
Description
The utility model relates to a kind of high-speed electric expreess locomotive.
High-speed electric expreess locomotive has higher requirements to the axiality of armature spindle and stator, to avoid high-speed electric expreess locomotive generation voice in service, oscillation phenomenon, for this reason, people improve a bearing pedestal of high-speed electric expreess locomotive, in the hope of the axiality of armature spindle is done some fine settings, for example Chinese patent CN2296091Y discloses a kind of high-speed electric expreess locomotive, it is provided with the retainer of being made up of becket and little steel ball in the periphery of bearing pedestal, during the high-speed electric expreess locomotive operation, utilize the slight movement of little steel ball that the axiality of high speed rotor of motor axle is finely tuned, make the motor even running.But the continuous slight movement of little steel ball can make the mating holes of the housing that is in contact with it produce wearing and tearing and groove, thereby make retainer lose fine setting centering effect, the axiality of armature spindle decreases, cause noise, vibration, minimizing electrical machinery life, in addition, it is higher that retainer is made required precision, and installation is difficult, cost is high.
The purpose of this utility model is to provide a kind of axiality of armature spindle can be finely tuned the high-speed electric expreess locomotive that the life-span is long, cost is low for a long time.
In order to achieve the above object, the technical solution of the utility model is: a kind of high-speed electric expreess locomotive, has armature spindle, fore bearing, front-end bearing pedestal, stator, rotor, housing, rear bearing, rear bearing block, adjustment spring and bonnet, has oil duct on housing and the front-end bearing pedestal, have oil through on the rear bearing block, between the hole wall of the outer peripheral face of rear bearing block and the mating holes of housing, be provided with the elastic bearing circle.
After adopting said structure, owing between the hole wall of the mating holes of the outer peripheral face of rear bearing block and housing, be provided with the elastic bearing circle, this elastic bearing circle can not damage the mating holes of housing, hole wall to mating holes keeps certain elasticity, thereby can carry out long-term fine setting to the axiality of armature spindle, motor can not produce noise and vibration, has so just prolonged electrical machinery life; In addition, the making of elastic bearing circle is simple, and it is also convenient to install, and cost is very low.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model high-speed electric expreess locomotive.
Structural representation when Fig. 2 is provided with an elastic bearing circle for rear bearing block.
As shown in Figure 1, high-speed electric expreess locomotive of the present utility model, has armature spindle (1), fore bearing (2), front-end bearing pedestal (4), stator (5), rotor (6), housing (7), rear bearing (9), rear bearing block (14), adjust spring (15) and bonnet (16), has oil duct (8) on housing (7) and the front-end bearing pedestal (4), has oil through (11) on the rear bearing block (14), between the hole wall of the mating holes (12) of the outer peripheral face of rear bearing block (14) and housing (7), be provided with elastic bearing circle (10), at this moment, preferably have two or more cannelures (13) on the outer peripheral face of rear bearing block (14), for example have three cannelures (13) as shown in Figure 1, elastic bearing circle (10) is " O " RunddichtringO, also elastic ring such as square-section sealing ring, and be arranged in the cannelure (13).
As shown in Figure 2, the outer peripheral face of rear bearing block (14) also can not driven cannelure (13), and directly tightly be enclosed within an elastic bearing circle (10) on the outer peripheral face of rear bearing block (14), two projections (10-1) are arranged on the outer peripheral face of this elastic bearing circle (10), and projection (10-1) contacts with the hole wall of the mating holes (12) of housing (7).The quantity that tightly is enclosed within the elastic bearing circle (10) on the rear bearing block (14) also can be two or more, certain spacing distance is arranged mutually during installation, each elastic bearing circle (10) can be only to be with a projection (10-1), also can be that top directly is the arch cross section.
As shown in Figure 1, also have annular oil groove (17) on the rear bearing block (14), this annular oil groove (17) communicates with oil duct (8) on the housing (7), and communicate with the oil through (11) on the rear bearing block (14), the purpose that goes up open loop shape oil groove (17) at rear bearing block (14) is to make the installation of rear bearing block (14) more convenient, the position that oil duct (8) on the housing (7) need only be aimed at annular oil groove (17) gets final product, and need not circumferentially locate rear bearing block (14) with screw again.
As shown in Figure 1, be fixed with protecgulum (3) on the front-end bearing pedestal (4), front-end bearing pedestal (4) also can be made as one with protecgulum (3), is referred to as front-end bearing pedestal or protecgulum.
The utility model also has some conversion, and for example, elastic bearing circle (10) also can be the elastic ring in star-like circle or other cross section, and its quantity can be one, also can be a plurality of.All fall within the protection range of the present utility model with up conversion.
