Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, and more specifically, to a bearing seat structure for a dough mixer. Background Art

[0002] The bearing seat is one of the commonly used mechanical parts in the field of mechanical transmission, and the bearing seat is involved almost wherever there is a bearing.

[0003] The bearing seat in the dough mixer is used as a connecting piece for connecting the driving mechanism of the dough mixer with the spiral stirring plate, so that the driving assembly drives the spiral stirring rod to rotate through the bearing seat to realize the dough mixing operation of the dough mixer; however, the existing assembly structure of the bearing seat is as follows Figure 3 As shown, the middle shaft on the bearing seat is only mounted on the middle shaft by an oil seal to perform a sealing operation. However, this sealing structure causes a gap between the oil seal and the middle shaft, and the oil seal is a one-way oil lock. When the driving motor drives the spiral stirring rod through the bearing seat to perform dough kneading operations, when there is a lot of dough, it is easy for the dough or other foreign matter to enter the bearing in the bearing seat through the gap between the oil seal and the middle shaft, thereby affecting the service life of the bearing. In addition, when the middle shaft on the bearing seat rotates at a high speed during operation, the high-temperature melted grease falls into the dough barrel of the dough mixer, affecting the dough kneading effect. For this reason, we propose a new bearing seat structure for a dough mixer. Utility Model Content
