Embodiment Construction

[0015] The motor stator pressure ring includes a ring-shaped steel sleeve 1, a ring-shaped structure and a tooth pressure plate 2 with a number of teeth uniformly distributed radially on the inner circle, and an annular stop 3 is opened at one end of the steel sleeve 1, and the annular stop 3 are provided with a number of threaded holes 4 along the circumference, and the outer circle of the tooth pressure plate 2 is an annular stepped structure. The pressure plate 2 is tightly fitted with the threaded hole 4 on the annular seam 3 through the hexagon socket bolt and washer assembly; the tooth pressure plate 2 is made of non-magnetic silicon-aluminum alloy.

[0016] During specific implementation, the annular stepped structure of the tooth pressure plate 2 is composed of the first annular stepped surface 5, the second annular stepped surface 6 and the third annular stepped surface 7 which are successively connected, wherein the first annular stepped surface 5 and the tooth pressu...

Abstract

The invention relates to the field of motor components, in particular to a motor stator clamping ring which comprises a steel sleeve and a tooth pressure plate, wherein the steel sleeve is in an annular structure; the tooth pressure plate is in an annular structure; a plurality of tooth parts are uniformly distributed on the inner circle of the tooth pressure plate in a radial manner; an annular spigot is formed in one end of the steel sleeve; a plurality of threaded holes are uniformly formed in the upper edge of the annular spigot along the circumference; the excircle of the tooth pressure plate is in an annular step structure; the tooth pressure plate is sleeved by the steel sleeve and is in stopping fit with the annular spigot through the annular step structure; the tooth pressure plate is in tight fit with the threaded holes in the annular spigot through a hexagon socket screw and a gasket assembly; and the tooth pressure plate is made of non-magnetic aluminum-silicon alloy. According to the motor stator clamping ring, tooth expansion of the tooth parts of an iron core punching sheet is effectively prevented besides that the tooth pressure plate has good mechanical property; meanwhile, good shield is formed by the tooth pressure plate at the end parts of an iron core; the loss of the end parts of a generator is reduced; and the problem of temperature rise of a winding is solved.

Description

technical field [0001] The invention relates to the field of motor components, in particular to a motor stator pressure ring, which is suitable for double-fed wind power generators, AC synchronous generators, asynchronous motor stator pressure rings, and can also be used in other motors. Background technique [0002] The stator pressure ring is an important part in the process of stator core lamination. The stator core is generally fastened by a pull screw, flat tie rod or buckle through the stator pressure ring, so that the stator core has a certain inter-plate pressure to achieve the purpose of core lamination. . At present, the motor stator pressure ring is generally processed from a whole piece of steel plate. As we all know, the leakage magnetic field of the stator coil produces additional loss in the metal structure near the end of the winding, which causes heat generation, resulting in an increase in the temperature of the winding. There is such a problem in the pre...
