The utility model discloses a rack and pinion jar is when the frequent reciprocating motion of rack, and the bolster does not need to be changed.
Description
Technical field
The utility model relates to gear rack cylinder field, is specifically related to a kind of buffer gear cold rack cylinder.
Background technique
In mechanical transmission fields, gear rack cylinder is a kind of common mechanism circular-rotation being converted into straight line motion.Usual gear rack cylinder adopts spring or rubber pad as shock absorber, but rubber pad exists not impact resistance, easily aging shortcoming, and spring existence is easily got rusty, the shortcoming of fatigue damage.Due in drive mechanism, tooth bar is high-frequent reciprocating motion, therefore uses the gear rack cylinder that rubber pad or spring are shock absorber shorter for working life, needs often to change rubber pad or spring, affects the working efficiency of transmission system.
Now be badly in need of a kind of gear rack cylinder not needing frequent exchange buffering part as can be seen here.
Model utility content
The purpose of this utility model is to provide a kind of gear rack cylinder not needing frequent exchange buffering part.
For achieving the above object, the technical solution of the utility model is as follows:
The base case that this programme provides is: a kind of buffer gear cold rack cylinder, comprise hydraulic cylinder and guiding cylinder barrel, this hydraulic cylinder removably connects with guiding cylinder barrel, the tooth bar being provided with piston in described hydraulic cylinder and being connected with piston, rotatingshaft is provided with in hydraulic cylinder, this rotatingshaft is provided with and tooth bar meshed gears, the shaft axis of hydraulic cylinder and the shaft axis conllinear of guiding cylinder barrel, end away from piston on tooth bar is provided with guide pad, this guide pad is provided with the first permanent magnet, the bottom of described guiding cylinder barrel is provided with the second permanent magnet repelled each other with the first permanent magnet.
Working principle and the advantage of this programme are: when specifically using the gear rack cylinder of this patent, the motion of pinion rotation band carry-over bar makes piston move near the end of hydraulic cylinder, liquid in hydraulic cylinder is compressed, guide pad is to the direction motion away from guiding cylinder barrel, and the spacing of the first permanent magnet and the second permanent magnet increases; When gear moves in the other direction, gear driven tooth bar moves to the direction away from hydraulic cylinder, be now negative pressure in hydraulic cylinder, guide pad is to the direction motion near guiding cylinder barrel end, the pitch smaller of the first permanent magnet and the second permanent magnet, magnetic force between first permanent magnet and the second permanent magnet increases, and is cushioned guide pad by magnetic force, and then realizes cushioning piston.
The ingenious feature utilizing magnet two like magnetic poles repel each other of this patent, utilizes magnetic force to cushion piston.Because permanent magnet has permanent magnetism, gear rack cylinder, under high-frequency work, can not affect the shock-absorbing capacity that the first permanent magnet and the second permanent magnet produce.Overcoming the shock absorbers such as traditional rubber pad, spring when cushioning, easily occurring the shortcomings such as aging, fatigue damage.
Preferred version one: based on the preferred version of scheme, described guiding cylinder barrel is provided with vent hole, and described rotatingshaft is provided with blade.Drive blade rotary while rotatingshaft driven gear rotates, blade rotary produces air-flow, and the air being conducive to guiding cylinder barrel outside enters in guiding cylinder barrel lowers the temperature to the Surface of action of wheel and rack.
Preferred version two: the preferably preferred version of: described disposed at air vent is provided with filter screen, this filter screen avoids impurity to fall in guiding cylinder barrel, affects the motion of guide pad.
Preferred version three: the preferably preferred version of two: the inner hole section of described guiding cylinder barrel is circular, the edge of guide pad is 0.02mm to 0.05mm with the gap of guiding cylinder barrel.The endoporus of guiding cylinder barrel is cross section is the processing that circle facilitates guide pad.Guide pad compares rationally with the gap of guiding cylinder barrel between 0.02mm to 0.05mm, when guide pad is less than 0.02mm with the gap of guiding cylinder barrel, very easily because of guide pad or guiding cylinder barrel expanded by heating, affects the steering capability of guide pad.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of buffer gear cold rack cylinder of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: hydraulic cylinder 10, piston 11, gear 12, tooth bar 13, blade 14, guiding cylinder barrel 20, vent hole 21, filter screen 22, guide pad 23, first permanent magnet 24, second permanent magnet 25.
Embodiment is substantially as shown in Figure 1: a kind of buffer gear cold rack cylinder, comprises hydraulic cylinder 10 and guiding cylinder barrel 20, and this hydraulic cylinder 10 is connected with guiding cylinder barrel 20 bolt, the shaft axis of hydraulic cylinder 10 and the shaft axis conllinear of the cylinder barrel 20 that leads.The tooth bar 13 being provided with piston 11 in hydraulic cylinder 10 and welding with piston 11, is provided with the rotatingshaft radial vertical with hydraulic cylinder 10, this rotatingshaft is provided with the tooth bar 13 and two pieces of blades 14 that engage with tooth bar 13 in hydraulic cylinder 10.The right part of tooth bar 13 is provided with guide pad 23, the right side of this guide pad 23 is embedded with the first permanent magnet 24, and the bottom of guiding cylinder barrel is provided with the second permanent magnet 25 repelled each other with the first permanent magnet 24.
Wherein, the middle part of guiding cylinder barrel has vent hole 21, and this vent hole 21 place is provided with filter screen 22.The inner hole section of guiding cylinder barrel is circular, and the edge of guide pad 23 is 0.05mm with the gap of guiding cylinder barrel.
During concrete this gear rack of use cylinder: the motion of gear 12 rotating band carry-over bar 13 makes piston 11 to left movement, and the liquid state in hydraulic cylinder 10 is compressed, and guide pad 23 is also to left movement, and the spacing of the first permanent magnet 24 and the second permanent magnet 25 increases.When gear 12 moves in the other direction, gear 12 is with carry-over bar 13 to move right, be now negative pressure in hydraulic cylinder 10, guide pad 23 also moves right, the pitch smaller of the first permanent magnet 24 and the second permanent magnet 25, magnetic force between first permanent magnet 24 and the second permanent magnet 25 increases, and is cushioned guide pad 23 by magnetic force, and then realizes cushioning piston 11.In addition, while rotatingshaft driven gear 12 rotates, band moving vane 14 rotates, blade 14 rotates and produces air-flow, has to utilize the air of guide cylinder cylinder 20 outside to enter in guiding cylinder barrel 20 lower the temperature to the Surface of action of gear 12 and tooth bar 13, the working life of prolongation gear 12 tooth bar 13.
The ingenious feature utilizing magnet two like magnetic poles repel each other of this patent, utilizes magnetic force to cushion piston 11.Because permanent magnet has permanent magnetism, gear rack cylinder, under high-frequency work, can not affect the shock-absorbing capacity that the first permanent magnet 24 and the second permanent magnet 25 produce.Overcoming the shock absorbers such as traditional rubber pad, spring when cushioning, easily occurring the shortcomings such as aging, fatigue damage.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
