A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings. Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are ball bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. X-Y tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
A device for CPD manikin respiratory motion
The application discloses a device for CPD dummy breathing movement, and relates to the technical field of in-vehicle living body detection targets, which is arranged in a chest cavity of a CPD dummy and comprises a driving motor, a driving gear, a driving rack, a sliding shaft mounting seat, a linear motion bearing, a sliding shaft and a breathing push plate. The driving motor is fixed with the driving gear through a driving shaft thereof, the driving rack is fixed on the sliding shaft in an axial direction, the driving gear is engaged with the driving rack, the sliding shaft is slidably connected with the sliding shaft mounting seat through the linear motion bearing, and the breathing push plate is fixed on one side of the sliding shaft. The driving motor drives the driving gear to rotate clockwise or counterclockwise, and drives the sliding shaft to move linearly through the meshing transmission of the gear and the rack, so that the breathing movement of the dummy is realized. The technical scheme of the application adopts the motor driving and gear and rack transmission mode to realize the breathing movement simulation, has small operation difficulty and good flexible adjustment, and can be applied to application scenes with high requirements on breathing frequency and amplitude.

Simple oil film lubrication structure of linear motion bearing
A simple oil film lubrication structure for a linear motion bearing includes at least two polygonal rod-shaped bearings paired with a slide block and a slide rail. The polygonal rod-shaped bearings are positioned in at least one recessed groove between the opposing surfaces of the slide block and the slide rail. Each recessed groove on both sides of the slide rail has an oil reservoir with a predetermined depth and height. An oil-applying spring with telescoping and binding elasticity is installed in the oil reservoir. The outer diameter of the oil-applying spring is equal to or smaller than the predetermined depth and height of the oil reservoir in the recessed groove of the slide rail. This constitutes a practical and innovative structure for simple oil film lubrication, effectively achieving simple oil storage structure, low cost, high lubrication efficiency, quiet and smooth movement, and dust and scale prevention.
