Description
Technical field：
The present invention relates to a kind of roller line slideway auxiliaries.
Background technology：
Roller line slideway auxiliary is that the roller in linear rolling guide is cylindrical roller, with spies such as high load, high rigidities
Point is mainly made of guide rail, sliding block, roller, reverser, retainer, end cover etc..
At this stage, roller line slideway auxiliary load operating for a period of time after, can be stayed in sliding block raceway and guide rail raceway
Lower roller runs trace.There are more apparent rollers to run trace in raceway, and at the corresponding raceway in roller both ends
There are two apparent parallel trace lines, this is because raceway can be considered as by without plane made of several Straight Combinations（That is raceway
Busbar is straight line）, and roller busbar also be straight line, roller both ends be arc transition curve, at this point, contact of the roller with raceway its
Stress distribution feature is as shown in Figure 1.
As seen from Figure 1, there is apparent edge effect in contact line both ends at this time, i.e., position is answered among contact line
Power distribution is more average, but the stress abruptly increase at both ends, considerably beyond the stress numerical at intermediate position, to occur connecing
The unusual distributed area of touch pressure is in particular in that sliding block raceway and guide rail raceway corresponding position can be because of the edge effects at roller both ends
And there is raceway abrasion, i.e., occur two parallel running orbits on roller surface.
Invention content：
The present invention is to provide a kind of roller line slideway auxiliary to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of roller line slideway auxiliary, including sliding block, guide rail and roller, it is described
Sliding block is connected to by roller slip on guide rail, and the sliding block is equipped with sliding slot, which is arranged along the length direction of guide rail,
It is equipped with the raceway for being used to support roller on the two side of sliding slot, rolling compatible with the raceway is equipped on the side wall of guide rail
Road slot, roller are placed between raceway and track groove, and the middle section of the busbar of raceway is straightway, and the straight line on the sliding block
The length of section is the 30 ~ 40% of raceway busbar overall length, and the both ends of the raceway busbar are divided into arc section.
Further, the middle section of the busbar of the track groove is straightway, and the length of the straightway is track groove
The both ends of the 30 ~ 40% of busbar overall length, the track groove busbar are divided into arc section.
The present invention has the advantages that：
The present invention is optimized for raceway busbar in roller line slideway auxiliary that can effectively reduce sliding block after logarithmic form and guide rail rolls
The abrasion in road improves the guideway service life.Especially when roller line slideway auxiliary high load, operation at high speed, in the raceway service life
While extension, guideway running stability also can be improved, reduce vibration and noise.
Description of the drawings：
Fig. 1 is roller and the stress envelope in sliding block when the contact of raceway in the prior art.
Fig. 2 is the structure chart of sliding block in the present invention.
Fig. 3 is the enlarged drawing of raceway in Fig. 2 sliding blocks.
Fig. 4 is the schematic diagram of raceway busbar in Fig. 2 sliding blocks.
Fig. 5 is the structure chart of middle guide of the present invention.
Fig. 6 is the enlarged drawing of track groove in Fig. 5 guide rails.
Fig. 7 is roller and the stress envelope in sliding block when the contact of raceway in the present invention.
Specific implementation mode：
The present invention will be further described below with reference to the drawings.
Such as Fig. 2 to Fig. 7, a kind of roller line slideway auxiliary of the present invention, including sliding block 1, guide rail 2 and roller, sliding block 1 pass through rolling
Son is slidably connected on guide rail 2, and sliding block 1 is equipped with sliding slot 11, which is arranged along the length direction of guide rail 2, in sliding slot
11 two side is equipped with the raceway 12 for being used to support roller, and raceway compatible with raceway 12 is equipped on the side wall of guide rail 2
Slot 21, roller are placed between raceway 12 and track groove 21.
The middle section of the busbar of raceway 12 is straightway on sliding block 1, and the length of the straightway is that 12 busbar of raceway is total
The both ends of long 30 ~ 40%, 12 busbar of the raceway are divided into arc section.
The middle section of the busbar of track groove 21 is straightway, and the length of the straightway is 21 busbar overall length of track groove
30 ~ 40%, the both ends of 21 busbar of the track groove are divided into arc section.
The busbar of track groove 21 in the busbar of raceway 12 in sliding block 1 and guide rail 2 is optimized for logarithm shape by the present invention,
Feature is that the middle section of busbar is straightway, and the length of the straightway is the 30 ~ 40% of busbar overall length, the both ends of busbar
It is divided into arc section, Curvature varying is accelerated when busbar is close to both ends, and specific bus equation is shown in formula（1）,
(1)
In formula：
Q --- raceway load
E ' --- sliding block, guide material elasticity modulus
A --- raceway half is long
B --- radius of roller
Raceway is shown in Fig. 7 with stress distribution feature when roller contact at this time, by Fig. 7 it can be seen that when raceway busbar is logarithm shape
When, stress distribution is more uniformly distributed, and does not occur the case where stress concentration.
Therefore sliding block and guide rail can effectively be reduced after raceway busbar in roller line slideway auxiliary being optimized for logarithmic form
The abrasion of raceway improves the guideway service life.Especially when roller line slideway auxiliary high load, operation at high speed, in the raceway longevity
While life extends, guideway running stability also can be improved, reduce vibration and noise.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
Protection domain.
