Abstract
The utility model relates to a motor part- a motor frame, specifically to a lightweighting motor frame, which solves the problems that it is difficult to manufacture a thin wall for the motor frame, thereby affecting full lightweighting to tow the motor. The lightweighting motor frame is provided with grooves evenly on an inner wall surface of the frame. In specific manufacture, wall thickness at the groove is 8mm. Through structure design of the grooves, according to the character of the nodular cast iron, the frame can be made into a thin wall at the grooves, thereby relieving weight of the frame, but also satisfying strength requirement of the frame, meanwhile the grooves are also used as ventilating ducts with a cooling function. The lightweighting motor frame in the utility model has compact and reasonable structure design, easy manufacture, thereby lighting the weight of the whole motor.
Description
Technical field
The utility model relates to a kind of motor component---electric machine stand, is specially a kind of light-weighted electric machine stand.
Background technology
Traction electric machine on the low-floor high speed light rail car needs lightweight, volume little.Traction electric machine needs to alleviate by the wall thickness that reduces support the weight of support for alleviating stator weight; Support adopts spheroidal graphite cast-iron to make, and existing electric machine stand is a uniform wall thickness, is satisfying under the situation of requirement of strength, and the support of this structure is difficult to do wall very thin (usually not can less than 10mm) when casting, thereby has influenced the abundant lightweight of traction electric machine.
Summary of the invention
The utility model is difficult to do wall very thin in order to solve existing electric machine stand, thereby influences the abundant light-weighted problem of traction electric machine, and a kind of light-weighted electric machine stand is provided.
The utility model is to adopt following technical scheme to realize: light-weighted electric machine stand evenly has groove in the inner wall surface of support.By the structural design of groove, utilize the characteristic of spheroidal graphite cast-iron, support can be made into thin-walled at groove, has both alleviated the weight of support, can satisfy the requirement of strength of support again, and groove also can be used as air duct simultaneously, and the ventilation refrigerating function is arranged.
Light-weighted electric machine stand structural design compactness described in the utility model, reasonable is processed easily, can alleviate the weight of motor complete machine.
