Description

Bearing block and washing machine with same

Technical Field

The utility model relates to a washing machine technical field, in particular to bearing frame and have its washing machine.

Background

At present, the driving mode of the drum washing machine mainly has two major directions, one of which is a belt transmission type drum washing machine represented by European brands such as Siemens; the other direction is a direct drive type drum washing machine represented by the korean brand such as LG. The difference between the two is that: the belt is used for transmission, and the kinetic energy generated by the motor is transmitted to a belt pulley of the washing machine through the belt, so that the drum is driven to rotate to wash clothes; the DD directly drives the transmission, and the rotor of the DD motor is directly connected with the main shaft of the roller to drive the roller to rotate and wash clothes. The DD direct drive is larger in motor load than belt drive, and has advantages over belt drive in the aspect of reducing noise of the washing machine.

For the existing motor direct drive type drum washing machine, the direct drive of the motor of the drum washing machine works as follows: the motor stator is fixed on a bearing seat, the bearing seat is connected with the barrel body into a whole (the bearing seat is embedded when the barrel body is produced), the motor rotor is fixed on a rotating shaft of an inner barrel (also called a roller), a bearing inner ring (rotating) is arranged on the rotating shaft of the inner barrel, a bearing outer ring (non-rotating) is fixed on the bearing seat, a bearing is fixed in the bearing seat in advance, and the bearing outer ring is tightly matched with the bearing seat and does not rotate; the rotating shaft on the roller is inserted into the bearing inner ring, and the rotating shaft and the bearing inner ring can synchronously rotate. Namely, the motor stator is fixed with the barrel body, the motor rotor is fixed with the inner barrel, and the barrel body and the inner barrel rotate relatively.

The DD that is sold in the market at present directly drives drum type washing machine's bearing frame structure:

1. the bearing seat is mostly an aluminum casting or an iron casting, and is embedded and injected into the rear wall of the rear outer cylinder in the injection molding process of the rear outer cylinder;

2. the stator of the DD motor is fixed on a bearing seat through a bolt, and a pre-positioning structure for assembling the stator is arranged on the bearing seat so as to ensure the rotating concentricity of the assembled stator and the main shaft of the roller;

3. the rotor of the DD motor is fixedly connected to the roller main shaft through a bolt or a nut;

however, the fixed knot who designs the DD stator constructs and location structure on the bearing frame, the most essential is to guarantee the concentricity of stator and cylinder rotation axis, the wrench movement when the motor operation probably causes the joint strength between bearing frame and the urceolus to reduce, washing machine is when moving, bring great load influence to the bearing frame easily, thereby reduce the life of bearing frame, bring not good experience for the user, and the processing of bearing frame locating hole is the existence error, lead to the concentricity of stator and cylinder rotation axis also to have certain deviation.
