## 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.

## Claims

### Claim 1

A transmission shaft and peripheral structure, comprising:
a first rotating shaft;
a bearing connected to the first rotating shaft;
a first frame connected to the bearing;
a second rotating shaft used for driving the first rotating shaft when the second rotating shaft rotates;
a second frame connected to the second rotating shaft;
a first gasket disposed under the bearing to cover the gap below the bearing;
a second gasket disposed above the bearing to cover the gap above the bearing,
wherein silicone oil is filled between the first gasket and the bearing and between the second gasket and the bearing, and
wherein the first rotating shaft has a groove corresponding to the second gasket.

### Claim 2 (depends on 1)

The transmission shaft and peripheral structure of claim 1, wherein silicone oil is filled between the first rotating shaft, the first frame, the second rotating shaft and the second frame.

### Claim 3 (depends on 1)

The transmission shaft and peripheral structure of claim 1, further comprising a cover connected to the first frame and adjacent to the first gasket, and silicone oil is filled between the cover and the first gasket.

### Claim 4 (depends on 3)

The transmission shaft and peripheral structure of claim 3, wherein the first frame has at least one groove corresponding to the cover.

### Claim 5 (depends on 1)

The transmission shaft and peripheral structure of claim 1, wherein the first gasket or the second gasket is mainly composed of silicone material.

### Claim 6 (depends on 1)

The transmission shaft and peripheral structure of claim 1, further comprising a first washer disposed between the upper side of the bearing and the first frame.

### Claim 7 (depends on 6)

The transmission shaft and peripheral structure of claim 6, wherein the first washer is mainly composed of silicone material.

### Claim 8 (depends on 1)

The transmission shaft and peripheral structure of claim 1, further comprising a second washer disposed between the first frame and the second frame.

### Claim 9 (depends on 8)

The transmission shaft and peripheral structure of claim 8, wherein the second washer is mainly composed of silicone material.
