Description
Technical Field
The utility model relates to a bearing technical field especially relates to a dynamic seal bearing.
Background
Roller bearings are one type of rolling bearings, and are one of the components widely used in modern machinery. It relies on rolling contact between the primary elements to support the rotating parts. Roller bearings are now mostly standardized. The roller bearing has the advantages of small moment required by starting, high rotation precision, convenience in selection and the like.
However, the conventional bearing has the following disadvantages: 1. the function is single, and the function of dynamic sealing is not realized; 2. good bearing lubrication is the decisive factor of guaranteeing the long-life operation of bearing, and it is crucial to reduce mechanical transmission energy consumption, but when lubricated, still prevent factors such as outside heat radiation, water, vapour, dirt, foreign matter entering to the damage of bearing, damage, current bearing seal effect is not good, and lubricating grease overflows easily, and then causes the pollution.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a dynamic seal bearing. Besides the traditional bearing function, the bearing is also added with a dynamic seal water supply function and a flexible self-sealing function; low cost, reliable operation, and reduced and eliminated pollution caused by bearing grease.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a dynamic seal bearing comprises an inner ring, an outer ring, a retainer, a roller, a dynamic seal stator and a dynamic seal; the inner ring is arranged in the outer ring, the retainer is arranged between the inner ring and the outer ring, and the roller is embedded in the retainer; the dynamic seal is arranged in the dynamic seal stator, the dynamic seal stator is arranged at two ends of the inner ring, the end surface of the dynamic seal stator is connected with the end surface of the outer ring, the end surface of the dynamic seal stator is in interference fit and bonding fit with the outer ring, and the inner diameter of the dynamic seal stator is in clearance fit with the outer diameter of the inner ring.
The length of the inner ring is greater than that of the outer ring, and the shape of the middle area is the shape of the standard bearing inner ring; the outer end area of the cylindrical shape is respectively matched with the dynamic seal stator and the dynamic seal to play a role of a dynamic seal rotor.
The dynamic seal stator is provided with a seal groove, and the dynamic seal is arranged in the seal groove of the dynamic seal stator and is a rubber seal ring, and a stet seal form is adopted.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model comprises an inner ring, an outer ring, a retainer, a roller, a dynamic seal stator and a dynamic seal; the end face of the dynamic sealing stator is connected with the end face of the outer ring, the end face of the dynamic sealing stator is in interference fit with the outer ring in a bonding way, the inner diameter of the dynamic sealing stator is in clearance fit with the outer diameter of the inner ring, and the dynamic sealing stator is rotationally connected with the inner ring and has a sealing function. The cavity of self sealss is formed with the outer lane to dynamic seal, inner circle, and the roller is located wherein, the utility model discloses the function of high-efficient self sealss has again simultaneously.
The utility model has the advantages that the dynamic sealing function is added besides the traditional bearing function, the high-efficiency self-sealing effect is generated, and the precondition is provided for canceling the lubricating system; the transmission system has the characteristics of reasonable design, simple process, reliable operation, reduction of the operating cost of the transmission system and the like; can reduce and eliminate the pollution generated by bearing grease.
