NUT- DRIVER

摘要

The nut turner is used for mechanized and automated two speed driving of nuts in the assembly of threaded elements in machine building and in electrical engineering. Driving at two speeds can be implemented with increased productivity and reliability. The design of the nut turner is simplified and technological with improved wear resistance of the elements. The nut turner consists of a body (1) with a built in electric motor (3) the output shaft (4) of which is fixed rigidly, directly to a monolithic body in the shape of a disc, which is a leading semi-clutch (7) of a twin gear clutch (5). Its driven semi-clutch is made of an outer (8) and inner (9) disc located in a single plane and forming a bearing with respect to each other with front teeth engaging the front teeth of the leading semi-clutch (5). The outer disc (8) is connected axially movably and elastically via spring (14) with adjustable tensioning to a bearing mounted in body (1) central gear wheel with internal teeth (16) on a planetary gear (6). The inner disc (9) is connected to a central gear wheel with outer teeth (13) to the planetary gear (6) and pressed to the leading semi-clutch (7) via a second spring (11) with adjustable tensioning. The satellite gears (18) of the planetary gear (6) located between the two central gear wheels with inner (16) and outer (13) teeth are bearing mounted to a planet carrier (17) connected to the output shaft (19) of the planetary gear (6) linked to the spindle. Adjustment of the tension of springs (11,4) is envisaged by regulating nuts (20,21).
