This utility model relates to the field of semiconductor technology and discloses a guide roller for a grinding and cleaning device, comprising: a rotating shaft, two bearings, and a receiving housing. The rotating shaft includes a first connecting section and a second connecting section that are detachably connected. The first connecting end has two mounting positions spaced apart along the axial direction. The two bearings are respectively sleeved on the two mounting positions of the first connecting end. The receiving housing is sleeved on the two bearings to rotate synchronously with the bearings. This utility model achieves good rotational performance through the rotating shaft and the bearing structure mounted on the rotating shaft. The housing that receives the wafer can effectively ensure the normal rotation of the rotating shaft through such a rotating structure. Combined with the dual bearing design, it effectively disperses mechanical stress, thereby improving the synchronization between the guide roller and the wafer rotation.

This utility model provides a three-cylinder pump, including a pump body, a piston, and a piston drive mechanism. The piston drive mechanism includes a drive shaft, an eccentric sleeve, an inner core of the eccentric sleeve, and a bearing. The inner core of the eccentric sleeve is a solid cylindrical structure. The drive shaft is fixed at an eccentric position on the inner core of the eccentric sleeve, and the drive shaft and the inner core of the eccentric sleeve are axially parallel. The eccentric sleeve is mounted on the outside of the inner core of the eccentric sleeve via a bearing, and a pin is provided on the outside of the eccentric sleeve. The distal end of the piston is hinged to the pin. The drive shaft drives the piston to perform reciprocating linear motion through the inner core of the eccentric sleeve, the bearing, and the eccentric sleeve. This three-cylinder pump has the advantages of stable and reliable transmission structure and longer service life.

This application relates to a three-dimensional rotating mechanical wall lamp. A motor drives the rotating housing to rotate, which in turn rotates the lamp, achieving continuous rotation of the mechanical wall lamp. The rotation speed can be adjusted and controlled. An extension post in the shaft hole increases the contact area between the rotating housing and the motor shaft, improving rotational stability. Bearings are installed on both the rotating housing and the stationary motor bracket to reduce friction between them, resulting in better rotation. The motor is positioned between the motor bracket and the motor base and is sealed to prevent dust from entering the motor. The connecting holes on the mounting base correspond to the fixing holes on the motor bracket, connecting the mechanical wall lamp to the mounting base. A recessed portion on the side of the rotating housing corresponds to the connecting hole; rotating the housing to misalign the recessed portion with the connecting hole conceals it. Positioning the connecting hole within the recessed portion allows for easy assembly and disassembly of the mounting base and the mechanical wall lamp, making operation more convenient.
