The invention concerns a compressor crankshaft, particularly a refrigerant compressor crankshaft ( 1 ) and a method for manufacturing such a crankshaft, with a shaft element ( 2 ), a crank pin ( 9 ) located eccentrically to the shaft element and a transition element ( 7 ) between the shaft element ( 2 ) and the crank pin ( 9 ). The purpose of the invention is to keep the manufacturing costs low. For this purpose, it is ensured that along its circumference the transition element ( 7 ) has at least one first reference point ( 20 ) and one second reference point ( 21 a , 21 b), with which the transition element ( 7 ) can be positioned in a holding fixture ( 25 ) of a working machine.

The invention provides a split type springless overrunning clutch which comprises a clutch body and a clutch cap, wherein the clutch body is mounted on a hydraulic motor shaft, and rotates synchronously along with the hydraulic motor shaft; the clutch cap is mounted on an electric motor shaft, and rotates synchronously along with the electric motor shaft; the cutch body comprises a cam, a backing ring and N rolling rods; the cam is located in the middle of the backing ring; the N rolling rods are located at the outer part of the cam, and are uniformly distributed along the edge of the backing ring; the cam adopts a circular structure; N working areas and N non-working areas are alternately distributed on the outer surface of the cam; the outer surface of each non-working area is matched with the inner surface of the edge of the backing ring; each working area comprises a meshing area and a separating area; the meshing areas are connected with the separating areas through transition slopes; the rolling rods are in contact with the meshing areas to realize meshing between the clutch body and the clutch cap; and the rolling rods are in contact with the separating areas to realize separation. Meshing and separating are realized by means of the inertia of the rolling rods and relative movement between the cam and the rolling rods, and the split type springless overrunning clutch is simple in structure, high in reliability, and convenient to disassemble, assemble and use.

The invention discloses a method and device for assembling a gear motor and a gear motor. The method and the device are used for assembling the driving gear and the driven gear of the gear motor. Themethod comprises the following steps that: the driving gear is made to rotate; and the driven gear and the driving gear are made to approach to each other along an axial direction, so that the gear teeth of the driven gear are plugged into the tooth slots of the rotating driving gear, and therefore, the full engagement of the driving gear with the driven gear can be realized. With the method and device of the present invention adopted, damage caused collision between the driving gear and the driven gear can be alleviated, gear damage caused during the assembly process of the gear motor, especially the assembly process of the driving gear and the driven gear can be greatly reduced, and the assembly quality of the gear motor can be ensured.

The invention provides a transmission parking system and a transmission parking system use method and relates to the technical field of automobile braking systems. The transmission parking system comprises a parking ratchet, a parking pawl and a time-delay mechanism. The parking ratchet meshes with the parking pawl. The time-delay mechanism is connected to the end, away from the parking ratchet, of the parking pawl and is used for pressing the parking pawl, or the time-delay mechanism is connected to the end, close to the parking ratchet, of the parking pawl and is used for lifting the parkingpawl, so that the parking pawl is arranged in the direction away from the parking ratchet under the action of the time-delay mechanism. The technical problems that in the prior art, when an automobile is operated from a D gear or an R gear to a P gear, a parking pawl and a parking ratchet are completely attached to bear force due to overturning of a power assembly, and the driving feeling of a driver is influenced are solved. The time-delay mechanism of the transmission parking system can provide certain acting force for the parking pawl, and the time need by meshing of the parking pawl and the parking ratchet is prolonged.

The invention provides a direct-pressing type carrier roller device with a wallpaper rotary screen. The direct-pressing type carrier roller device comprises a body of the rotary screen, a carrier roller and a pushing device, wherein the carrier roller is mounted on a carrier roller arm; the carrier roller arm is connected with the pushing device; the carrier roller arm is arranged on the mounting seat by a sliding mechanism. The sliding mechanism comprises a slide rail and a slide block; the slide rail is arranged on the mounting seat and the slide block is arranged on the carrier roller arm. The mounting seat is mounted on a fixed frame; the fixed frame is provided with a limiting rotary seat; the limiting rotary seat is provided with a carrier roller limiting swing arm; the carrier roller limiting swing arm is coaxially provided with a rotary shaft of the limiting slide block and a limiting wheel; the mounting seat is provided with a limiting slide block; the limiting wheel can rotate around the rotary shaft of the limiting slide block and can slide in a groove of the limiting slide block. According to the direct-pressing type carrier roller device, the accurate problem of an engaged point between the body of the rotary screen and a carrier roller generatrix is solved; the rapid engagement and the accurate adjustment between the body of the rotary screen and the carrier roller is realized; the direct-pressing type carrier roller device has a very important effect on improving the quality of screen body of the rotary screen.
