Abstract

The utility model relates to a metallurgical gear rack oscillating oil cylinder, comprising oil cylinders and piston rods, wherein a rack is fixedly installed in the middle part of each oil cylinder body; each rack is engaged with a gear sheathed on a gear shaft; and the gear shaft is linked with a power output shaft. The metallurgical gear rack oscillating oil cylinder is simple in overall structure and scientific and rational in design; in such a way, the oil cylinder scratch problem is effectively prevented; the service lives of each piston and each cylinder barrel are prolonged; the strength of an oscillating cylinder box body, the strength of contact between the gear and each rack and the bending strength meet strength requirements can be met; and each rack not only has enough strength, but also has enough rigidity, so that the requirements of severe working environments are met.

Description

Metallurgical gear rack oscillating oil cylinder
Technical field
The utility model belongs to metal working fluid and is installed with standby technical field, relates to a kind of metallurgical gear rack oscillating oil cylinder.
Background technique
Existing its structure of gear rack oscillating oil cylinder is to be fixedly mounted with tooth bar between two pistons in cylinder barrel, makes the tooth bar left and right displacement by the power of piston in cylinder barrel, and the rack drives gear swings.Its shortcoming is: tooth bar and both sides piston are that rigidity is fixedly mounted with, and cause easily the damage of piston and the scuffing of cylinder body, cause easily and hit the cylinder phenomenon working life of having reduced thus piston and cylinder body, cause the operation of oscillating oil cylinder not smooth, and Safety performance reduces.
The model utility content
In order to overcome the above-mentioned shortcoming of prior art ,The utility model provides that a kind of overall structure is simple, layout is reasonable, has prolonged piston and cylinder barrel working life, and the existing enough intensity of tooth bar has again the metallurgical gear rack oscillating oil cylinder of enough rigidity.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of metallurgical gear rack oscillating oil cylinder, comprise oil cylinder and piston rod, middle part at cylinder block is fixed with tooth bar, and this tooth bar is meshed with gear on being sleeved on gear shaft, and gear shaft is connected with pto=power take-off.
Be provided with hydraulic fluid port above cylinder block, hydraulic fluid port connects by oil pipe and cylinder cavity.
Described cylinder diameter is φ 100mm.
Described diameter of piston rod is φ 95mm.
The working stroke of described piston is 163.5mm, pendulum angle
The beneficial effects of the utility model are: overall structure is simple, design science is reasonable, effectively avoided oil cylinder to scratch problem, piston and cylinder barrel working life have been prolonged, contact strength, the flexural strength of swing cylinder casing intensity, gear rack all satisfy requirement of strength, the existing enough intensity of tooth bar has again enough rigidity, has satisfied the requirement of abominable working environment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-tooth bar, 2-gear, 3-gear shaft, 4-oil cylinder, 5-piston rod, 6-oil pipe, P1, P2-hydraulic fluid port.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of metallurgical gear rack oscillating oil cylinder, comprise oil cylinder 4 and piston rod 5, above oil cylinder 4 cylinder bodies, be provided with hydraulic fluid port P1 and P2, hydraulic fluid port P1 and P2 connect by oil pipe 6 and oil cylinder 4 inner chambers, middle part at oil cylinder 4 cylinder bodies is fixed with tooth bar 1, and this tooth bar 1 is meshed with gear 2 on being sleeved on gear shaft 3, and gear shaft 3 is connected with pto=power take-off.
When concrete the making: structure and the technical parameter of this metallurgy gear rack oscillating oil cylinder are respectively: oil cylinder 4 diameters are that φ 100mm, piston rod 5 diameters are that the working stroke of φ 95mm, piston is the 163.5mm(pendulum angle ), working pressure is 16MPa, and test pressure is 24Mpa, and working medium is YB-N446, and moment of torsion is 14592 N.M.
The working principle of above-mentioned metallurgical gear rack oscillating oil cylinder is: when gear rack oscillating oil cylinder P1 oil-feed, tooth bar 1 promotes sun gear shaft 3 swing that turns clockwise, thereby driving mechanical rotates, P2 hydraulic fluid port oil return this moment, on the contrary, P2 oil-feed, P1 oil return, sun gear shaft 3 counterclockwise rotates, and output shaft is counterclockwise, and driving mechanical rotates.Because work is abominable, concentrate the fatigue ruption that produces for preventing tooth bar 1 stress, require tooth bar 1 should have enough intensity that enough rigidity is arranged again, therefore select 20CrMoT, modified and whole nitriding is processed; Gear shaft 3 is selected superior alloy steel 42CrMo, and quenching and tempering hardness is: HB260-290.
