Abstract
The invention discloses a kind of roller line slideway auxiliary device, comprise guide rail, be movably installed with slide block on the guide rail, guide rail both sides and slide block internal surface respectively are provided with two raceways up and down, be provided with cylindrical rollers in guide rail raceway and the slide block raceway, the slide block installed inside has the rolling element retainer, and the Line of contact of described guide rail raceway and slide block raceway and cylindrical rollers is that straight line and two ends are the build-up curve of transition curve; This product is because guide rail raceway and slide block raceway all are designed to guarantee the transition curve of optimum contact stress state, lower manufacture cost, and adopted the high and little cylindrical rollers of form error of dimensional accuracy, thereby made roller line slideway auxiliary device have highi degree of accuracy, high rigidity and feature of long life.
Description
Technical field
The present invention relates to a kind of linear guide pairs, particularly a kind of rolling element is the line slideway auxiliary device of roller.
Background technique
At present, Chang Gui roller line slideway auxiliary device comprises guide rail 1 in the world, slide block 2 is installed on the guide rail, guide rail both sides and slide block internal surface respectively are provided with the plane raceway, plurality of rollers 3 is set between the raceway of plane, be fixed with roller reverser end cap at slide block 2 two ends, slide block 2 installed inside have rolling element retainer 4.When slide block 2 relative guide rails 1 move, shuttling movement in roller 3 can be done infinitely in slide block 2.
The section form of roller line slideway auxiliary is with reference to Fig. 1, and guide rail raceway 11 and slide block raceway 21 cross sections are straight line shape.For line contacts, wrapping angle α is 45 ° between roller 3 and guide rail raceway 11 and the slide block raceway 21.The roller that adopts in the world has following several form at present:
1, with reference to Fig. 2, roller 3 is cylindrical, and this roller dimensional accuracy and accuracy to shape height with batch roller 3 size shape precision high conformities, are convenient to produce in batches, and cost is low.But under guiding pairs was subjected to external load function, especially under the torque load effect, roller 3 contacted the contact stress that produces with guide rail raceway 11 and mainly concentrates on roller 3 two ends with slide block raceway 21, thereby directly influences the working life of roller guide pair.
2, with reference to Fig. 3, roller 3 is designed to cydariform, can avoid producing the stress concentration phenomenon like this, improves the life-span.But so make the bearing capacity of roller guide pair descend, rigidity is low, and the manufacture cost of cydariform roller is higher simultaneously, and cannot say for sure to demonstrate,prove with the precision conformity of batch cydariform roller.
3, with reference to Fig. 4, it is cylinder that roller 3 is designed to intermediate section, and two ends are the shape of transition curve, can overcome the generation of two ends stress concentration phenomenon like this, contact stress district is in a big way arranged again simultaneously, make improve working life, the load capacity of while roller guide pair, rigidity improves.But the roller of this transition curve is made complicated, the cost height, and the precision conformity of criticizing together be cannot say for sure to demonstrate,prove.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind ofly be convenient to make, the roller line slideway auxiliary device of machining accuracy height, long service life.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of roller line slideway auxiliary device, comprise guide rail, be movably installed with slide block on the guide rail, guide rail both sides and slide block internal surface respectively are provided with two raceways up and down, be provided with cylindrical rollers in the raceway, the slide block installed inside has the rolling element retainer, and the Line of contact of described guide rail raceway and slide block raceway and cylindrical rollers is that straight line and two ends are the build-up curve of transition curve.
As further improvement in the technical proposal, the Line of contact of described cylindrical rollers and guide rail raceway and slide block raceway and horizontal line angle are 45 °.
The invention has the beneficial effects as follows: this product is because guide rail raceway and slide block raceway all are designed to guarantee the transition curve of optimum contact stress state, lower manufacture cost, and adopted the high and little cylindrical rollers of form error of dimensional accuracy, thereby made roller line slideway auxiliary device have highi degree of accuracy, high rigidity and feature of long life.

Embodiment
With reference to Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of roller line slideway auxiliary device, comprise guide rail 1, be movably installed with slide block 2 on the guide rail 1, guide rail 1 both sides and slide block 2 internal surfaces respectively are provided with two raceways 11 up and down, 21, be provided with cylindrical rollers 3 in guide rail raceway 11 and the slide block raceway 21, slide block 2 installed inside have rolling element retainer 4, when slide block 2 relative guide rails 1 move, shuttling movement in cylindrical rollers 3 can be done infinitely in slide block 2, described guide rail raceway 11 and slide block raceway 21 are that straight line 51 and two ends are transition curve 52 formed build-up curves with the Line of contact of cylindrical rollers 3, described guide rail raceway 11 and slide block raceway 21 all adopt emery wheel correction postforming grade grinding, thereby effectively guarantee the shape and size precision of raceway.
The present invention for reach the four directions to etc. the characteristics of load, described cylindrical rollers 3 is 45 ° with the Line of contact and the horizontal line angle of guide rail raceway 11 and slide block raceway 21.
This product is because guide rail raceway 11 and slide block raceway 21 all are designed to guarantee the transition curve of optimum contact stress state, lower manufacture cost, and adopted the high and little cylindrical rollers 3 of form error of dimensional accuracy, thereby made roller line slideway auxiliary device have highi degree of accuracy, high rigidity and feature of long life.
