1, face of slideway of linear playground slideway by a certain number of planar composition, from make, assemble and examine for, planar amount should as far as possible little. The basic and sectional appearance of sharp movement slideway sees a picture 1. Graph the rectangular slideway of · of basic and sectional appearance of slideway of 1 sharp movement has stiffness tall, carrying capacity is large, make, examine to go to the lavatory with maintenance, but oriented precision is poorer; · triangle slideway directs function and vertex angle α are concerned, α jumps over small oriented sex to had been jumped over, but coefficient of friction of equivalent of area of the slideway when α is reduced is increased; α horn increases carrying capacity to increase. When bearing slideway is protruding triangle, not easy stockpile has bigger accumulate bits, keep lubricating oil not easily also. When bearing slideway is sunken triangle, slideway effect of dynamic pressure of deputy easy generation, but dustproof sex is poor; Slideway of form of · swallow end is triangular slideway be out of shape. Its height is lesser, can bear overturn pitching moment; Dan Gang spends difference, make, examine and maintenance is no-go; · is cylindrical slideway is easy make, not easy stockpile is bigger accumulate bits and lube, after wearing away, be adjusted hard and compensate clearance. Basically use at getting the circumstance of axial load. 2, sharp movement sliding slideway is commonly used assorted form (see a picture 2) graph sliding slideway of 2 sharp movement is commonly used assorted form 3, carrying capacity of slideway of planar cirque of · of circular motion slideway is large, make convenient, can bear only axial load, beard and main shaft couplet are used, will bear by main shaft radial load. Multi-purpose at vertical lathe, circular table grinder; Its generatrix dip often takes slideway of · cone cirque 30 ° , oriented sex is better than planar slideway, can bear axial and radial load, but the coaxial that holds cone and axes line harder is spent; Slideway of cirque of · V form can bear bigger axial force, radial load and overturn pitching moment, the coaxial that assures cone and axes line harder is spent. 4, design and the computational · job according to the machine tool condition, performance characteristics, select right slideway kind; · chooses the sectional figure of sliding slideway; · chooses method of right slideway stuff, heat treatment to wait; · slideway gets consideration of force analysis, intensity of pressure, have the structural design of slideway and consideration; · designs slideway to adjust space plant and compensation method; · design is lubricant, defend systematic unit; · makes slideway treatment, constructional technology demand.
