Abstract
The present invention relates to a gear speed change device. The gear speed change device includes a housing, a bearing, a bearing sealing structure, a gear shaft, a gear and an oil-blocking structure. The bearing sealing structure is used to seal the bearing. The gear shaft is connected to the inner wall of the housing through the bearing. The gear is mounted on the gear shaft and is located in the housing. The gear is used for speed change, and a gap is formed between the gear and the housing. The oil-blocking structure is arranged on the flow path of the grease in the housing to prevent the grease from flowing through the gap to the bearing sealing structure. When the grease in the above-mentioned gear speed change device flows along the flow path during leakage, the oil-blocking structure can first block part of the grease from flowing through the gap. Even if a small amount of grease is not blocked by the oil-blocking structure, its leakage can be further prevented by the bearing sealing structure. This can improve the anti-oil leakage effect of the gear speed change device.
