Description

The present invention relates to a linear guide device, and more particularly to an axially extending rail, a slider, and a plurality of rows of ball chains and a lubrication system. In order to provide sufficient and long-term lubrication when the ball chain circulates and to increase the moving speed of the linear guide device, the lubrication system circulates in the circulation path provided in It is related with the linear guide apparatus which strengthened.

  The linear guide device includes a rail, at least one slider, and a plurality of rows of ball chains. A rail groove extending in the axial direction is provided on the left and right outer sides or the upper side of the rail. The slider includes at least a rigid body, front and rear end covers, and front and rear sealing members. A plurality of rows of track grooves corresponding to the track grooves of the rail are provided inside the legs of the rigid body. The slider is provided with a rigid raceway groove, a ball chain transfer path, and a circulation path composed of folded rolling paths at both ends of the ball chain transfer path, front and rear end covers are provided on the outer edge of the folded rolling path, and the sealing member is Fixed to the outer surface of the end cap. The slider is straddled on the rail, and each ball chain rolls between the slider and the raceway groove of the rail. Enter the other end of the track groove from the runway. The circulating circulation of each ball chain allows the slider to move on the rail without any travel restrictions.

The lubrication necessary for long-term circulation of each ball chain includes a system in which an oil storage device is provided on a slider to achieve permanent lubrication, in addition to a system that performs re-lubrication. Is fixed to the front or rear surface of the slider, and this lubricating oil supply device has an application device that contacts the rail, applies lubricant to the rail, and a lubricant absorber is located next to the application device, Provided to the coating device, and further includes an oil amount control device to control the oil amount. Lubricating oil is applied to the outer rail of the slider, and when the slider moves beyond its length, the ball chain located in all the track grooves can be lubricated. The length increases. A channel is provided in the oil storage groove, and it is connected to other oil storage grooves, is used as an oil filler port, or is connected to an opening to the outside of an external oil feeding device. In the channel, felt, fiber, polymer, etc. The material having the oil feeding function is directly left by the capillary phenomenon, and the automatic oil feeding effect is achieved. Further, the lubricating oil supply device disclosed in Patent Document 2 includes a casing and an oil storage block, the lubricating oil supply device is fixed on the slider, and the oil storage block comes into contact with the track groove of the rail so that the lubricating oil is on the rail. Apply. An oil storage groove is installed on the slider, and an absorbing material that absorbs the lubricating oil is provided in the oil storage groove. Further, the oil feed pipe is connected to the oil storage groove and the lubricating oil supply device, the oil feed pipe is filled with fibers, and directly contacts the absorbent material and the oil storage block in the oil storage groove, and the lubricating oil in the oil storage groove is stored in the oil storage block. Supplied on top. Since the shape of the bypass may be complicated and three-dimensional, it is difficult to cut and fill, and it is also difficult to fill the oil feed material fiber into a long and narrow oil feed pipe, especially when the oil feed pipe is thin.

In addition, the end cover on the outer edge of the folded rolling path generally has a complicated shape formed by plastic injection molding. Bolts are fixed to both ends of the rigid body of the slider, and the load area of the raceway groove and the folded rolling path are connected. The end cover, which is a part of the rail, is limited by the rail track groove, and the outer edge of the folded rolling path needs to be gradually reduced to prevent interference with the rail track groove. Is the weakest part, and is similarly subject to the height restriction of the linear guide device. In general, since the lowermost turn-around rolling path is close to the lower edge of the end cover, the location of the fixing bolt is away from the connection area between the load area of the track groove and the turn-back rolling path and the lower edge of the end cover under space restrictions. In general, the upper edge part of both legs of the rigid body at the position, when the moving speed of the slider increases, the impact that the ball chain gives to the outer edge of the turning path increases, the end cover receives the impact, and the end cover impact Stress is easily generated between the receiving portion and the portion fixed by the bolt, and is easily damaged. At the same time, the lower edge part of the end cover and the part where the load area of the raceway groove and the turning rolling path are connected easily open to the outside due to this impact, and the position of the turning rolling path moves to circulate the ball chain. It doesn't go smoothly. Generally, since the sealing member or oil storage device fixed to the outer surface of the end lid is joined only to the end lid, the joining rigidity between the end lid and the rigid body of the slider cannot be increased.
