摘要： Ball screw device (100) comprising a shaft (1) and at least two nuts (2). Each nut (2) comprises a plurality of balls which transform the rotary movement of the shaft (1) into a linear movement. The nuts (2) are joined to one another through a joint element (4) which moves integrally with the nuts (2), said joint element (4) being configured to move a load element (5) which causes an axial force (F) on the joint element (4). The joint element (4) is designed to distribute said axial force (F) among all the nuts (2) arranged in the shaft (1), such that each nut (2) supports a predetermined axial load (f1, f2). The invention also relates to the method for designing the joint element (4) of the ball screw device (100).

摘要： The present disclosure relates to the technical field of aerial work platforms, in particular to a linear actuator with a contact type safety nut and a fault detection method thereof. The linear actuator includes a central screw, a driving nut mechanism, a safety nut mechanism, and a driving control assembly. The central screw has a screw raceway. The safety nut mechanism includes a safety nut seat sleeved at the periphery of the central screw. Limit hole channels pointing to the central screw are arranged on the safety nut seat. An elastic buffer element is arranged in each of the limit hole channels. A safety ball is arranged between the elastic buffer element and the central screw. The driving control assembly includes a motor for driving the central screw to rotate and a motor controller for controlling the motor to operate.

摘要： The present invention relates to an electro-mechanical actuator assembly (1) for actuating a brake actuator (20), comprising:
an actuation mechanism (3, 6) configured to convert a rotational driving movement into a translational driven movement in a direction of a first longitudinal axis (L1), and
a transfer mechanism (4, 4', 5) operatively coupled to the actuation mechanism (3, 6) to receive and transfer the translational driven movement at least in the direction of the first longitudinal axis (L1),
wherein the transfer mechanism (4, 4', 5) comprises at least one pushing member (4, 4') having a pushing member pivot portion (4c, 4c') configured to allow a tilting movement of the pushing member (4, 4') about a pivot axis (17) inclined to the first longitudinal axis (L1).
