Sliding parts are provided wherein a plurality of pumping areas for generating pumping action via the relative rotational sliding of a stationary ring and a rotating ring is discontinuously formed in a circumferential direction on a sealing face of one of the stationary ring and rotating ring so as to communicate with a sealed fluid-containing space. The pumping areas are provided with intake pumping areas operating in a direction in which the sealed fluid is drawn in and outflow pumping areas operating in a direction in which the sealed fluid is expelled. A plurality of dynamic pressure-generating grooves for generating dynamic pressure via the relative rotational sliding of the stationary ring and the rotating ring are formed in a circumferential direction on a sealing face of the other of the stationary ring and the rotating ring so as to communicate with the sealed fluid-containing space.

The present invention relates to a movable door device with rollers, in particular to a movable glass door device with a good slide-guiding property. The movable glass door device comprises a piece of movable door glass and a roller runner which is respectively arranged on the upper edge or the lower edge of the movable door glass; wherein, the upper edge or the lower edge of the movable door glass is vertically connected with a slide-guiding plate; the opening of the roller runner faces backwards; the upper and the lower runner plates of the roller runner are respectively connected with a roller; the horizontally arranged slide-guiding plate of the movable door glass are inserted between the rollers, which are respectively arranged on the upper and the lower sides of the slide-guiding plate; and the upper or the lower edge of the movable door glass is respectively inserted into a groove arranged in the upper or the lower runner plate of the roller runner. The present invention mainly resolves the technical problem that the arrangement of the slide-guiding structure of the prior movable glass door requires the movable door glass to have a certain thickness. When the movable glass door device is used, the slide-guiding structures of the upper and the lower ends of the movable glass door device can have the same slide-guiding effect.

Sliding parts are provided where a plurality of dynamic pressure-generating grooves for generating dynamic pressure via the relative rotational sliding of the stationary ring and the rotating ring are formed in a circumferential direction on a sealing face of one of a stationary ring and the rotating ring so as to communicate with a sealed fluid-containing space, and pumping areas for generating pumping action via the relative rotational sliding of the stationary ring and the rotating ring are formed within the dynamic pressure-generating grooves.

The invention discloses a method for avoiding the idle run and slide of the wheels of railway motor trolley, comprising following steps: centralized processing and output the measured each axial speed including axial speed, inter-axial sliding speed difference, and inter-axial idle run speed difference; selecting the lower one of speed and controlling speed of driver as limited speed; calculating the limited speed difference between limited speed and each axial speed; selecting the larger one of limited speed difference and inter-axial idle run speed difference as idle speed difference; selecting the larger one of limited speed difference and inter-axial sliding speed difference as sliding speed difference; using the idle speed difference to calculate the de-loading coefficient in the drawing condition and processing the de-loading process; using the sliding speed difference to calculate the de-loading coefficient in the braking condition and processing the de-loading process; and processing the spreading-sand process when the spreading-sand value set by driver equals to the idle run speed difference or sliding speed difference. The invention has stable property, simple structure, lower cost and better effects to avoid the idle run and slide.

This invention makes it possible to obtain smooth sliding properties at the contact parts of sprags and tongue parts, which bias the sprags in the direction of engagement, in a sprag-type one-way clutch. A plurality of pockets (52) are formed, at intervals in the length direction of an elongated belt-shaped plate part (51) formed from sheet metal, by punching, which is a type of shearing processing, and tongue parts (54) that protrude inside the pockets (52) are provided on one side of pillar parts (53) formed between adjacent pockets (52) in the peripheral direction. The belt-shaped plate part (51) is bent into a circular shape and installed between an outer ring (10) and an inner ring (20), and the sprags (30), which are respectively inserted into the pockets (52), are biased in the engagement direction by the tongue parts (54). The sliding properties are improved by bending the belt-shaped plate part (51) such that a shear drop (58) formed on the cut edge surface of the sheared edge of the tongue part (54) is on the outer diameter side, and bringing the shear drop (58) into contact with the sprag (30).

The invention provides a telegraph pole transportation drawing head. The telegraph pole transportation drawing head comprises a sleeve containing a pole head of a telegraph pole. After the front end face of the sleeve is closed, the bottom wall of the sleeve extends forwards to form a sliding plate. A rib plate is axially and fixedly arranged on the axial symmetric line between the outer wall of the sleeve and the sliding plate. A plurality of fixing through holes are formed in a rib plate body from front to back. When the telegraph pole transportation drawing head is implemented specifically, the fracture surface of the sliding plate is of an arc-shaped V shape, gradually shrinks and extends upwards in an inclined mode, the valley bottom of the V shape and the bottom face of the rib plate are fixedly connected into a whole, and the forefront end face of the rib plate protrudes from the front end face of the sliding plate and is of a vertical arc-shaped structure. When the telegraph pole transportation drawing head is used, due to the fact that the shape of the sliding plate is similar to that of the bottom face of a bow, when the telegraph pole is drawn to slide forwards on soil, especially on soft soil, the resistance is small, effort is saved, and the sliding effect is good. The telegraph pole transportation drawing head can be bound with cables and drawing is quite convenient.
