Abstract: An electric motor includes a motor housing (5) which includes cooling ribs (15) on the peripheral side leading away heat arising in the motor. The cooling ribs (15) only extend over a part of the periphery of the motor housing (5), so that cooling ribs (21) of the electronics housing (13) have space in the cooling-rib-free part of the motor housing (5). The cooling ribs (21) of the electronics housing (13) are arranged aligned with the cooling ribs (15) of the motor transversely to a motor axis (14).
Abstract translation: 一种电动机包括电动机壳体(5),该电动机壳体(5)包括在周边的冷却肋(15),引导电动机中产生的热量。 冷却肋(15)仅在电动机壳体(5)的周边的一部分上延伸,使得电子设备壳体(13)的冷却肋(21)在电动机壳体的无冷却肋部分中具有空间 (5)。 电子设备壳体(13)的冷却肋(21)与马达的冷却肋(15)布置成与马达轴线(14)横向对齐。

Abstract: A clamping ring (11) for the connection of two flanges includes an open ring section (17) which is designed for receiving the flanges (9, 10) to be connected. The flanges (9, 10) have ends connected by way of a clamping device (21-27) which is attached on the ring section (17). With the clamping device (21-27), the ends of the ring section (17) can be moved onto one another and thus the clamping ring (11) can be clamped amid the integration of the flanges (9, 10). The clamping device (21-27) includes a clamping force limitation device (27), in order to prevent an unintended failure of the clamping device (21-27) on assembly.
Abstract translation: 用于连接两个凸缘的夹紧环(11)包括敞开的环形部分(17),其设计成用于接收要连接的凸缘(9,10)。 凸缘(9,10)具有通过附接在环形部分(17)上的夹紧装置(21-27)连接的端部。 通过夹紧装置(21-27),环形部分(17)的端部可以彼此移动,因此夹紧环(11)可以在凸缘(9,10)的整合中被夹紧。 夹持装置(21-27)包括夹紧力限制装置(27),以便防止夹紧装置(21-27)在组装时的意外故障。
