[0003] However, ordinary bearings are immersed in a small amount of lubricating oil when they leave the factory (because there is no oil storage structure), which will be consumed quickly during use. When the lubricating oil is lost, the bearing will soon be damaged. Most of the linear bearings on the market are not used. With refueling kit

The invention relates to the field of bearings, and discloses a linear bearing with automatic oil supply during operation, which includes a bearing casing, a cage inside the bearing casing, and balls inside the cage. The cage is provided with a flow path for the balls to roll. The two ends of the cage are equipped with annular oil storage tanks, and oil storage pads and lubricating oil for lubrication are placed in the oil storage tanks. There is a pressure plate in the oil storage bin, and a moving mechanism for driving the pressure plate to move is arranged in the oil storage bin. The transmission mechanism includes a transmission part, a roller connected to one end of the transmission part and a drive plate controlled by the movement of the transmission part. There is a rotary column in the oil tank, and the pressure plate is connected with the rotary column by threads. The rotary column rotates with the rotation of the drive plate. The rotation of the rotary column drives the pressure plate to move towards the oil storage pad, and squeezes the oil storage pad to drive the lubricating oil in the oil storage pad. Squeeze out and enter the flow channel through the oil guide hole.
Description
technical field [0001] The invention relates to the field of bearings, in particular to a linear bearing with automatic oil supply during operation. Background technique [0002] With the continuous increase of mechanical automation production lines, the application of precision transmission components is more extensive, and the requirements for the accuracy and service life of linear bearings are higher. When the linear bearing is working, the rolling friction between the steel ball and the raceway must have lubricating oil to form a lubricating film between the steel ball and the raceway to avoid direct contact between the steel ball and the raceway, otherwise the surface of the steel ball and the raceway will Sliding friction is formed, and the contact point of the working surface is under the action of load, causing it to wear rapidly, causing fatigue spalling and shortening the service life of the bearing. [0003] However, ordinary bearings are immersed in a small amo...
