Abstract

The invention relates to the field of machinery, and discloses a chip removal type linear sliding bearing and a precision casting method and a machine casting method thereof.The chip removal type linear sliding bearing comprises a bearing sleeve with a channel, and the channel penetrates through the two ends of the bearing sleeve; the supporting strip is fixed on the side wall of the channel; the macromolecular structure wraps the supporting strips and is connected with the supporting strips; a plurality of macromolecular structures surround in the channel to form a shaft channel, and two adjacent macromolecular structures and the side wall of the channel surround to form a longitudinal chip removal channel; the multiple supporting strips are arranged around the axis of the shaft channel at equal intervals. Smooth and low-noise operation of the sliding shaft under the complex working condition is achieved, the friction force borne by the sliding shaft is reduced, the situation that chippings affect movement of the sliding shaft in the shaft channel is avoided, and the application range is widened.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a chip removal type linear sliding bearing and its precision casting method and machine casting method. Background technique [0002] Compared with the existing ball type linear bearing, the ball bearing requires lubrication due to the mutual contact between the balls. This therefore makes them more susceptible to maintenance, especially dirt and moisture, which is why ball bearings are often fitted with dust covers or sealing plates. [0003] However, the inventor realized that the linear sliding bearings with internal balls or cage structures are not only prone to displacement or vibration of the balls or cage structures due to external shocks or vibrations, resulting in that the sliding shaft cannot be smooth and low Noisy operation; it is also easy to cause dirt such as debris brought into the interior of the linear bearing by the sliding shaft, causing the contact surface between t...
