    • The invention relates to a bevel gear, the rim gear (2) of which is produced by injection moulding with a plastic around a base body (l). The aim of the invention is to produce an inventive bevel gear in which there is a connection between the base body (1) and the rim gear (2) the strength of which also permits the transmission of high torques. The base body (1) of the inventive bevel gear is embodied as a flange, around the disc-shaped region (1') of which the plastic rim gear (2) is injection moulded. The region (1") of reduced diameter adjacent to the region (1') forms a hub for rotationally fixed mounting of the bevel gear on a shaft. According to the invention, the flange region (1') has, axially on both sides, several recesses (3, 3'), distributed around the circumference thereof running principally in the axial direction but not extending through said region (1'). The recesses (3, 3') have a swallow-tailed form such that the sections (4, 4') of the outer circumference of the region (1') remaining between them are back-cut by the edges of the recesses (3, 3') running in the axial direction.
    • 本发明涉及一种螺旋齿轮,所述环形齿轮(2)由注射模制的基体(L)与一个塑料形成。 目的是提供一种通用的螺杆轮,其特征在于,所述基体(1)与所述链轮(2)之间有一个其强度也允许大的扭矩可靠的传输的连接。 所提出的螺旋齿轮的所述基体(1)被形成为一个凸缘,所述盘形部分(1“)与塑料环形齿轮(2)被封装。 位于区域(1“)的直径减小的邻接区域(1“)形成用于在轴上的螺旋齿轮的旋转固定的安装轮毂。根据本发明,区域(1' 的凸缘轴向两侧在每种情况下几个),分布在其圆周上, 布置在轴向方向上延伸的主要的区域(1“)没有通过凹部突出的(3,3”)。凹部(3,3“)的燕尾形的,从而在它们剩余部分之间的支架(4 通过在凹部(3,3“的轴向方向上边缘延伸)“的区域(1的外周的)” 4)是底切。
