Inlay steel bushing low pressure casting motor casing front and back end cover

一种镶钢套低压铸造电机壳前后端盖

Abstract

本实用新型公开了一种镶钢套低压铸造电机壳前后端盖,其特征在于,其包括钢套,及通过低压铸造,包覆在钢套外围的端盖,所述钢套设有防脱槽及防转槽,所述端盖形成与防脱槽及防转槽相适配的卡凸。防脱槽防止钢套与端盖脱离,防转槽防止钢套与端盖产生相对转动。针对现有新能源汽车永磁伺服电机前、后端盖,采用低压铝合金铸造,一次成型,产品外形光滑、弧线分明;为了增加强度,在轴承位置镶钢套,解决轴承受热轴承位变形的问题,增加了轴承位的硬度。
The utility model discloses an inlay steel bushing low pressure casting motor casing front and back end cover, its characterized in that, it includes the steel bushing, and through the low pressure casting, the cladding is at steel bushing outlying end cover, the steel bushing is equipped with the anticreep groove and prevents the turn trough, the end cover forms with the anticreep groove and prevents that the card of turn trough looks adaptation is protruding. The anticreep groove prevents that steel bushing and end cover break away from, prevents that the turn trough prevents that steel bushing and end cover from producing relative the rotation. To before the present new energy automobile permanent magnetism servo motor, the rear end cap, adopt low jewelling alloy casting, one shot forming, the product design is smooth, the pitch arc is clearly demarcated, in order to gain in strength, put at bearing position and inlay the steel bushing, solve the bearing problem that bearing position warp of being heated, increased bearing position's hardness.
