The purpose of this utility model can also adopt following technical measures to solve:
As execution mode more specifically, be provided with the space region gap after the distortion of elasticity trim ring between described elasticity trim ring and the gland.
Above-mentioned elasticity trim ring includes trim ring central authorities arch upward portion, trim ring annular recess and trim ring annular dimpling edge from the inside to the outside respectively, trim ring central authorities arch upward and offer the bearing trepanning in the portion, the arch upward bearing trepanning periphery of portion of trim ring central authorities extends many places bearing paw, the space region gap of gap between trim ring annular recess and the corresponding gland after for the distortion of elasticity trim ring, trim ring annular dimpling edge contacts with gland periphery bottom, and has between annular dimpling edge of trim ring and the bearing chamber inwall and radially adjust free clearance.
Described elasticity trim ring can be the steel plate trim ring, or the elasticity trim ring made of other material.
Described gland includes gland central authorities arch upward portion and gland annular recess from the inside to the outside respectively, and the portion of arching upward of gland central authorities has the gland through hole, and gland through hole external diameter is greater than the trim ring portion that arches upward.
The bearing chamber opening part of described die casting end cap is provided with the riveter point of a plurality of stationary gland along its periphery.
The beneficial effects of the utility model are:
(1) end-cap assembly used of the utility model electrical micro-machine, by top gland is set at bearing chamber, the elasticity trim ring is set between gland and the oiliness bearing, and make to be provided with to have between the madial wall portion of elasticity trim ring and bearing chamber and adjust gap freely, can solve the problem of low-power machine low pressure starting, both guaranteed that the electric motor starting performance was good, the low and consistency of starting voltage has been saved great amount of manpower for producing again preferably simultaneously, has directly reduced production cost.
