    Abstract: A gearbox housing (1) comprises a housing body (10) and an annular gear (40). The housing body (10) comprises an annular support (20) extending along an axial direction (A) and a lateral portion (30) provided at a side face of the annular support (20) perpendicular to the axial direction (A), the lateral portion (30) comprising a hole (32) formed thereon for an input shaft to pass through. The annular gear (40) is provided inside of the housing body (10) along a radial direction (R) and adapted to couple to the annular support (20), wherein a plurality of teeth (42) are circumferentially provided at an inner side of the annular gear (40), and wherein a gear wheel (50) with an output shaft (52) is adapted to couple to the plurality of teeth (42). The gearbox housing (1) can reduce the shrinkage of the material during the manufacturing, thereby improve the accuracy of the gearbox housing (1).
