  • Publication number: 20220112937
    Abstract: Provided are a motor device and a method for manufacturing the same that can accurately and consistently provide a support shaft to a case and enhance the strength for fixing the support shaft to the case. A small-diameter part having a smaller diameter than a large-diameter part is formed through drawing. The large-diameter part and a step part are embedded in a gear case. The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±?) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.

  • Publication number: 20220112940
    Abstract: An actuator includes a housing, an extension arm, and a threaded spindle. The threaded spindle is mounted on the housing in such a way as to be rotatable with respect to an axis of rotation by a first rotary bearing. The extension arm projects out of the housing in such a way that it can be moved in a direction of the axis of rotation. The housing and the extension arm together delimit an internal space, the volume of which changes when the extension arm moves. A first end of the threaded spindle that is remote from the first rotary bearing, projects into a tubular section of the extension arm, irrespective of a position in which the extension arm is situated. The tubular section extends with a constant internal cross-sectional shape along the axis of rotation.

    Abstract: A gear system includes at least one gear stage, a pump system and oil channels for circulating a first lubricant oil flow via first elements of the gear stage and a second lubricant oil flow via second elements of the gear stage, and an oil conditioning system for controlling temperatures of the first and second lubricant oil flows so that the temperatures of the first and second lubricant oil flows are different from each other and flow rates of the first and second lubricant oil flows are different from each other. Thus, it is possible to utilize for example the fact that bearings do not need as much oil flow as gear wheels but, on the other hand, lowering oil temperature of the bearings provides more advantages than lowering oil temperature of the gear wheels.

    Abstract: A valve includes a valve body, valve arm hinge and valve piston. The valve arm hinge connects the valve arm to the valve body through a pivoting connection. The valve piston moves linearly in a valve piston channel. When a pressurized fluid contacts a second valve piston end, a force is applied to a second valve piston end. Movement of the valve arm from a first valve arm position to a second valve arm position allows the valve piston to move, under the force applied from closed, to open and allows fluid to flow through a valve channel. The float in the first valve arm position is above the position of the float when in the second valve arm position. If fluid in the tank goes below a critical tank fluid level, the valve arm moves from the first valve arm position to the second valve arm position.

    Abstract: A drain system includes a drain body attachable to a subfloor and configured for attachment to a pipe member below the subfloor. A seal component is positionable between the drain body and the pipe member and is arranged to form a seal therebetween. The seal component has a body including open upper and lower ends defining an opening therethrough for receiving a portion of the pipe member. An outer surface of the body defines an interface between the seal component and the drain body arranged to permit a first angular movement between the seal component and the drain body. An inner surface defines an interface between the seal component and the pipe member and is arranged to seal and permit a second angular movement between the seal component and the pipe member, wherein the second angular movement is different than the first angular movement.

  • Publication number: 20220112976
    Abstract: A system for applying a chemical agent within a pipe includes a skid assembly, moveable longitudinally within the pipe. The skid assembly has a bottom positionable on a bottom, internal portion of the pipe. A delivery nozzle is carried by the skid assembly and is coupleable to a chemical agent supply. A dispensing tip delivers a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The tip is held at or above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip is limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface.
