The invention discloses a controllable bidirectional reversing controller. The controllable bidirectional reversing controller comprises a fixed base, n rolling columns, a rotational lug plate and an output box body, wherein a circular-barrel-shaped body sleeves a locking shaft; the output box body sleeves the circular-barrel-shaped body of the rotational lug plate, with a gap therebetween; the output box body is connected with the fixed base through a bearing to form a rotational motion pair; the rolling columns are installed in groove holes respectively, and gaps are arranged among the rolling columns, the left sides and the right sides of the groove holes of the rotational lug plate, and the inner side of the output box body; and from a cross section, each rolling column is distributed on each side of a regular n-sided polygon along a circumferential direction and tangential with the midpoint of each side, and the circular-barrel-shaped body of the rotational lug plate keeps that the axis of each groove hole is corresponding to the midpoint of the corresponding side of the n-sided polygon on the fixed base in a free state. The invention further discloses a controllable bidirectional reversing device using the controllable bidirectional reversing controller, and a reversing reduction device.
Description
technical field [0001] The invention relates to the field of mechanical transmission, in particular to a controllable bidirectional backstop controller, a controllable bidirectional backstop device and a backstop deceleration device. Background technique [0002] At present, in various variable speed transmission devices of mechanical transmission, not only the functions of torque transmission and speed change need to be realized, but also in order to ensure the safe and normal operation of the equipment, it is necessary for the equipment to be able to brake and stop at any position during operation. For example, the lifting device suddenly loses power, especially in the elevator industry, using a controllable two-way backstop controller can greatly improve its safety and reliability. Most of the braking devices of traditional transmission equipment adopt the brake system, and the friction plate is the main component. Many situations will occur in the use of this brake devic...
