Abstract
The utility model provides a motor bearing chamber for a wind driven generator, which is provided with a wave-shape spring, comprising a bearing, an inner bearing cover, an outer bearing cover, an end cover and a wave spring, wherein the inner bearing cover and the outer bearing cover are arranged on two ends of the bearing and are provided with a relative lug boss and the end cover is arranged on the lug boss between the inner bearing cover and an outer bearing cover and is on the upper end of the bearing. The gap between the lug boss surface of the outer bearing cover and the relative bearing surface is preset. The wave spring is arranged in the gap between the bearing and the outer bearing cover. The utility model which relates to a motor bearing chamber equipped with the wave-shape spring for the wind driven generator could improve the performing reliability of a motor front bearing and a motor back, improve the bearing usage span and reduce the maintenance work of the motor.
Description
Technical field
The utility model relates to a kind of bearing chamber, relates in particular to a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring.
Technical background
In wind-driven generator, alternating current machine is owing to tilt to install, can cause the axial compressive force of bearing, owing to be subjected to the influence of use occasion and the restriction of cabin Undercarriage structure in the air at height, its base often is fixed on horizontal direction to tilt on 5 ° the elastic supporting piece, and 5 ° of installations because motor tilts when installing will be subjected to the influence of rotor gravity pressure and cause the bearing premature failure for the bearing of an end.In addition, because the particularity of wind-driven generator use occasion, maintenance of motor is difficulty relatively, so wind-driven generator is to the quite high reliability of integral arrangement needs of motor.How the reliability that improves motor by the roof pressure power that increases bearing is that the utility model is demanded the problem being devoted to solve urgently.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art, and a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring is provided, and this bearing chamber is owing to be provided with wavy spring, thereby has improved the forward and backward bearing reliability of operation of motor greatly.
The purpose of this utility model is achieved through the following technical solutions, a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring, comprise bearing, be located at the inside cap with relative boss and the outer bearing cover at bearing two ends and be in inside cap and outer bearing cover between boss on and be positioned at the end cap of bearing upper end, wherein, also comprise a wavy spring, leave the space between the boss face of described outer bearing cover and the bearing surface relative with it, described wavy spring is installed in the space between bearing and the outer bearing cover.
Above-mentioned a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring, wherein, described wavy spring is that an anchor ring is corrugated annulus, its relative end cap bottom surface vertically is placed in the space.
A kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring of the present utility model, owing between bearing and outer bearing cover, set up a wavy spring, increased the precompression of bearing, bear part and tilt to install the axial compressive force that causes bearing because of motor, improve the forward and backward bearing reliability of operation of motor, thereby can increase the useful life and the maintenance that has significantly reduced motor of bearing.
Description of drawings
Fig. 1 is the structural representation of the bearing chamber of a kind of wind-driven generator motor that is provided with wavy spring of the present utility model.
Embodiment
Below in conjunction with accompanying drawing a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring of the utility model is described further.
See also Fig. 1, a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring, comprise bearing 3, be located at the inside cap 1 and the outer bearing cover 5 of the relative boss 11 of having of bearing 3 two ends and 51, be on the boss 11 and 51 between inside cap 1 and the outer bearing cover 5 and be positioned at the end cap 5 and a wavy spring 4 of bearing 3 upper ends, wavy spring 4 is that an anchor ring is corrugated annulus, leave the space between 3 on 51 of the boss of outer bearing cover 5 and the bearing relative with it, wavy spring 4 is installed in the space between bearing 3 and the outer bearing cover 5 and relative end cap 5 bottom surfaces are vertical is placed in this space.
Because it is big that wavy spring 4 has rigidity, the strong characteristics of buffering vibration absorption ability, it can increase the precompression of bearing 3, bears part and tilts to install the axial compressive force that causes bearing 3 because of motor, thereby improve the forward and backward bearing reliability of operation of motor.
Above embodiment is only for the usefulness of explanation the utility model, but not to the restriction of the utility model protection range.Relevant those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion or modification, and the technical scheme that all are equal to should belong to also within the category of the utility model protection, is limited by each claim.
Claims (2)
1. bearing chamber that is provided with the wind-driven generator motor of wavy spring, comprise bearing, be located at the inside cap with relative boss and the outer bearing cover at bearing two ends and be in inside cap and outer bearing cover between boss on and be positioned at the end cap of bearing upper end, it is characterized in that: also comprise a wavy spring, leave the space between the boss face of described outer bearing cover and the bearing surface relative with it, described wavy spring is installed in the space between bearing and the outer bearing cover.
2. a kind of bearing chamber that is provided with the wind-driven generator motor of wavy spring according to claim 1 is characterized in that: described wavy spring is that an anchor ring is corrugated annulus, and its relative end cap bottom surface vertically is placed in the space.
