摘要： In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.

摘要： A railway freight car truck is provided with an elastomeric suspension device between the bolster end and the sideframe spring support surface. The elastomeric device is usually of an elongated oval shape. The elastomeric device takes the place of one or more rows of coil springs that comprise the suspension resting on the sideframe support surface. The freight car truck bolster is supported on the coil springs under empty car conditions and both the coil springs and the elastomeric device under fully loaded car conditions.

摘要： A pressure control system and means for pressure pouring of cast steel wheels, including a control system and a main gas circuit. The control system includes an upper computer, a PLC unit, a sensor, an operation box and an electronic valve. The upper computer is connected via a signal line with the PLC unit which is connected with each of the sensor, the operation box and the electronic valve. The sensor includes an inside-tank pressure sensor and an inside-mold liquid level detecting sensor. The electronic valve includes a quick breaking valve and a servo valve. The main gas circuit includes a gas pressure bag, a ball valve, a pressure reducing valve, a solenoid valve, and a pressure tank. The gas pressure bag, the ball valve, the pressure reducing valve, the solenoid valve and the pressure tank are connected with one another via gas tubes.

摘要： A control valve includes a diaphragm with a flow path with a predetermined cross-section from a brake pipe to a first side of the diaphragm and another flow path having another predetermined cross-section from a second side of the diaphragm to atmosphere. A dump valve prevents flow from the brake pipe to atmosphere. A method for operating a control valve includes supplying brake pipe air to a first side of a diaphragm through a flow path having a predetermined cross-section and permitting or preventing reference air flow to atmosphere through another flow path having another predetermined cross-section. The method further includes supplying reference air to a dump valve that prevents brake pipe air flow to atmosphere.

摘要： A slinger for a roller bearing seal includes (a) an inner section extending at least in a first direction parallel to a rotation axis of the slinger, encircling the rotation axis and forming a plurality of tabs configured to pressure fit the slinger onto a rotor of a roller bearing seal, (b) an outer section extending at least in the first direction at a greater distance than the inner section from the rotation axis and encircling the rotation axis, and (c) a middle section encircling the rotation axis and spanning between the inner section and the outer section, wherein the inner section, the middle section, and the outer section define respective portions of a single continuous part.

摘要： A retaining valve includes an inlet and a valve member downstream from the inlet, wherein the valve member has first, second, and third positions. A first passage through the valve member allows fluid flow through the retaining valve when the valve member is in the first position. A second passage through the valve member allows fluid flow through the retaining valve when the valve member is in the second position. A third passage through the valve member allows fluid flow through the retaining valve when the valve member is in the third position. A slide moves with respect to the valve member in response to pressure at the inlet. A spring engaged with the slide biases the slide toward the inlet. A seal located at an axial midpoint of the slide prevents flow through the third passage when pressure at the inlet is less than a predetermined pressure.

摘要： A draft gear assembly for use with railcars having coupler members is provided. The draft gear assembly has front and back ends and comprises a yoke, a coupler follower, a front resilient member, an intermediate stop member, and a back resilient member. The yoke has a back wall, a top wall extending from the back wall toward the front end of the draft gear assembly, and a bottom wall extending from the back wall toward the front end of the draft gear assembly. The coupler follower is positioned between the butt end of the coupler shank and the front end of the draft gear assembly. The front resilient member is positioned between the coupler follower and the intermediate stop member. The back resilient member is positioned between the intermediate stop member and the yoke back wall. The front and back resilient members are compressible.
