Radiaxial bearing having a cylindrical configuration centered on a central axis, the bearing having at least one harmonic wave-type reduction stage and including three or more rings and a first ring-shaped arrangement of rolling elements, each being centered on the central axis, the three or more rings enclosing the ring-shaped arrangement of rolling elements such that a) an innermost of the rings has a race in contact with the rolling elements from radially inward, an outermost of the rings has a race in contact with the rolling elements from radially outward, and a third ring, and possibly a fourth ring, has or have a race or races in contact with the rolling elements axially from both sides, or b) the three or more rings have four races contacting the rolling elements in a rectangular box formation, the box formation being oriented at an oblique angle with respect to the central axis of between 0° and 360°, wherein two opposed races have structures with different spatial frequencies that are designed to force the rolling elements into a harmonic-wave type oscillation between the structured races and translating a fast rotation of a ring with a structured race having a low spatial frequency into a slow rotation of a ring having a race with a high spatial frequency during operation of the bearing, wherein the ring or one of the rings that has or have the races that are oriented perpendicular to the structured races has separators separating adjacent rolling elements from one another, and to an electric motor. At least one of the structured races is structured such as to form an obstruction having at least one curve oscillating in a direction perpendicular to the direction of the rolling elements and contacting the rolling elements off-center such that the rolling elements partially protrude beyond the obstruction by varying amounts.

The utility model discloses a butterfly valve production processing equipment, including support plate, drive subassembly, transmission subassembly, adjusting subassembly, telescopic piece and slide bar, drive subassembly drives transmission subassembly to operate, transmission subassembly drives mounting block opposite movement, mounting block opposite movement carries out the clamping fixed of valve body, has promoted the stability of valve body processing process, has improved the production efficiency, has improved the production efficiency. When the valve body is overturned, the adjusting assembly drives the rotating shaft connected with the adjusting assembly to rotate slowly, the rotating shaft can drive the indicating rod at one end to rotate in the rotating process, the rotating angle can be adjusted and controlled through the angle value pointed by the indicating rod, then the overturning angle of the valve body can be adjusted, and the practicability of the device is improved; and the arranged telescopic piece can drive the illuminating lamp at one end of the sliding rod to move, and then the position of the illuminating lamp can be adjusted, so that the illuminating lamp can better provide good light for constructors in the valve body machining process.

The utility model discloses a welding device for ethylene tank production and processing, which comprises a base, a welding device and a welding device, the V-shaped supports are fixedly connected to the top of the base at equal intervals in the front-back direction, and the inner walls of the two sides of each V-shaped support are each rotationally provided with two supporting wheels. According to the utility model, a series of structures are arranged, so that the ethylene round tank to be welded can be directly hoisted in or out by personnel in a manner that the upper part is not shielded and movably supported, and the V-shaped supporting manner is utilized, so that the ethylene round tank to be welded with various diameter specifications can be movably supported conveniently, the applicability is improved, and the labor intensity is reduced. And the supporting wheels can be driven to tightly extrude the to-be-welded ethylene round can through the anti-skid rubber sleeves in a pressure control mode and drive the to-be-welded ethylene round can to rotate slowly in a friction mode, workers can directly conduct whole-circle welding work on one side conveniently, the phenomena that labor is wasted due to surrounding walking, inconvenience is caused due to dragging of a welding gun pipe, and welding precision is affected are avoided, and welding convenience and labor saving performance are improved.
