Abstract: A gearbox with motor fixing structure is used to fix a motor on the gearbox. The motor has a body and a shaft protruding from the leading edge of the body. The gearbox with motor fixing structure comprises a box and a metal part. The box has a gear set configured inside. An outer edge of a side wall of the box has a first hole. The metal part is configured inside the box. The motor is embedded in the first hole. The leading edge of the body of the motor is locked on the metal part, and the shaft of the motor passes through the metal part into the box to connect with the gear set.

Abstract: The present inventive concept discloses to a cleaning apparatus for cleaning both sides of the glass panel. The cleaning apparatus comprises two cleaning components attracted to each other and attached on opposite sides of the glass panel. Each of the cleaning components comprises a body, a cleaning module, and a plurality of magnetic modules. The body has a central portion and a peripheral portion. The body has plurality of grooves on a bottom surface of the peripheral portion. Each of the magnetic modules has a magnetic wheelset disposed in the groove and exposed on the bottom surface of the body. The two cleaning components are adsorbed to opposite sides of the glass panel by the magnetic attraction of the magnetic wheelsets. One of the cleaning components could be driven by a motor to rotate itself and drive the other cleaning component on the opposite side of the glass panel to rotate together.

Abstract: A gearbox with flow guiding structure comprises a box and an oil retaining ring. The box has a gear set configured inside. The gear set comprises a worm and an epicyclic gear set engaged with the worm. The box comprises an upper casing and a lower casing. The upper casing is disposed on the lower casing. An oil retaining wall is disposed on the bottom of the upper casing. The oil retaining wall is disposed inside the lower casing sidewall when the upper casing is engaged with the lower casing, and is disposed around the epicyclic gear set. The oil retaining ring is disposed around the epicyclic gear set. The outer side wall of the oil retaining ring has a curvature.

Abstract: The present invention provides a fast detachable polishing plate mechanism. The fast detachable polishing plate mechanism includes a polishing plate and a rod. The polishing plate has an adhesion unit disposed on the lower surface of the polishing plate. The rod connects straightly to the upper surface of the polishing plate. The rod is divided into an upper section, a middle section and a lower section from top to bottom, and only the middle section has a thread. The present invention further provides a hand-held machine tool having a drive shaft. The drive shaft has a tapped hole. The fast detachable polishing plate mechanism is mounted to the hand-held machine tool through the rod being inserted to the tapped hole.

Abstract: A transmission shaft comprises a first rotating shaft and a second rotating shaft. The first rotating shaft has a first connecting end. The second rotating shaft has a second connecting end. The first connecting end is used for driving the second connecting end to rotate the second rotating shaft when the first rotating shaft rotates.

Abstract: A transmission shaft and peripheral structure comprises a first rotating shaft, a bearing, a first frame, a second rotating shaft, a second frame, a first gasket and a second gasket. The bearing is connected to the first rotating shaft. The first frame is connected to the bearing. The second rotating shaft is used for driving the first rotating shaft when the second rotating shaft rotates. The second frame is connected to the second rotating shaft. The first gasket is disposed under the bearing to cover the gap below the bearing. The second gasket is disposed above the bearing to cover the gap above the bearing. Silicone oil is filled between the first gasket and the bearing and between the second gasket and the bearing.
