4 results about "Radial position" patented technology

The invention relates to a dynamic radial load measurement mechanism for a bearing support, which comprises a mounting base, a support sleeve, a force measurement frame and an end cover, wherein the first side of the support sleeve is mounted on the mounting base; the force measurement frame is mounted on the support sleeve; the force measurement frame comprises a force bearing inner ring, multiple radial supporting parts, and multiple force sensors; the force bearing inner ring is mounted at the inner circle of the support sleeve; the inner circle of the force bearing inner ring is used for mounting a bearing and a rotor; the outer circle of the force bearing inner ring is provided with multiple mounting grooves; each force sensor is mounted in the corresponding mounting groove respectively; one end of each radial supporting part abuts against each corresponding force sensor, and the other end is contacted with the support sleeve to enable the support sleeve to limit the radial position; and the end cover is arranged at the second side opposite to the first side of the support sleeve. Measurement can be executed in a condition of not changing the stiffness of the original support system.

The invention provides a closed type heavy-load thin wall light-duty pulley device and belongs to the technical field of heavy industrial machinery. The device comprises an end cover, a wheel hub, two webs and a rope groove which are annular and are connected in sequence from inside to outside, and further comprises a shaft which is arranged inside an inner ring of the end cover, a bearing for supporting the shaft and an inner ring supporting sleeve for positioning the bearing. The two webs are located at the positions on the two side faces of the pulley device and are at the same radial position of the pulley device. The wheel hub and the end cover are fixed by a stainless steel wire rope; an outer ring of the end cover is connected with the wheel hub; a gap being not more than 0.1mm is formed between the inner ring of the end cover and the inner ring supporting sleeve. An inner cavity composed of the wheel hub, the end cover, the inner ring supporting sleeve and the shaft is fully filled with lubricating grease to form a closed structure. The closed type heavy-load thin wall light-duty pulley device is free of maintenance; the lubricating grease can be fully filled in one time and does not need to be replaced within 4-5 years; meanwhile, the pulley device which has lighter self weight, greater load and smaller wall thickness is effectively realized and the service life of the pulley device is greatly prolonged.

A closure device designed to be put in place on, or removed from, a container, including a cap carrying at least two security projections, each provided with an axial locking abutment that can be moved radially between a cooperation position, in which the axial locking abutment engages with an axial locking abutment carried by the container, in order to hold the cap on the container, and a separation position, in which the axial locking abutment is separated from the axial locking abutment carried by the container. The closure device further includes a security ring snap-fitted onto the cap. The security projections are arranged on an internal surface of the security ring and the radial position of each axial locking abutment changes, by ovalization, from its cooperation position to its separation position.

The invention discloses a continuously variable transmission. The continuously variable transmission comprises a first shaft, a second shaft, a pair of driving rings and a control mechanism, wherein the first shaft rotates by carrying a first disc; the second shaft rotates by carrying a pair of second discs, and the second discs are arranged in a spaced mode along the second shaft; the first shaft and the second shaft make the first disc be located between the second discs and overlap with the second discs, and the surfaces, opposite to the second discs, of the first disc incline; the driving rings are located between the first disc and the second discs located at the two opposite sides of the first disc, and the end surfaces of the driving rings make contact with the surfaces, opposite to the second discs, of the first disc, so that power is transmitted between the first shaft and the second shaft; and the control mechanism is used for driving the driving rings to move relative to the first disc and the second discs, so that the relative radial positions of the driving rings, the first disc and the second discs are changed, and accordingly the speed of the continuously variable transmission is changed.
