Abstract
The invention discloses an oil pressure jack guide pillar eccentric wheel. The oil pressure jack guide pillar eccentric wheel comprises a metal shell. A center bearing is arranged inside the metal shell. Guide pillars are evenly arranged on the outer side of the center bearing. The guide pillars are connected to the metal shell through corresponding connecting plates. Each guide pillar is provided with a corresponding eccentric swing blade. Oil jacks are arranged inside the corresponding guide pillars. The center bearing comprises a seamless bearing body. A center oil-way sleeve is arranged on the outer side of the seamless bearing body. The outer side of the center oil-way sleeve is connected with an oil-way shell through oil-way shell fixing rods. Guide pillar mounting bases are arranged on the outer side of the oil-way shell. Due to the fact that the guide pillars with the eccentric swing blades are arranged on the outer side of the eccentric wheel, a motion track of the eccentric wheel is made more accurate and stable in the using process, the conditions of noise, vibration and the like in the swinging process of the eccentric wheel are effectively avoided, the service life of the eccentric wheel is prolonged, working efficiency is improved and the oil pressure jack guide pillar eccentric wheel is worthy of being popularized.
Description
Technical field
The present invention relates to mechanical equipment technical field, specially a kind of oil pressure oil top guide pillar eccentric wheel.
Background technology
Jack is a kind of simplest crane gear of lifting highly less than 1m, with rigidity top lift part as work clothes
Put, by the light small crane gear of top bracket or bottom claw the jacking weight in stroke, be divided to mechanical and two kinds of fluid pressure type,
Jack is mainly used in the departments such as factories and miness, communications and transportation as the work such as Mechanical Help and other liftings, support, its light structure
Firm, flexibility and reliability a, people can carry and operate, and jack uses instrument in extensive range as a kind of, employs optimal
The cast of matter, it is ensured that the quality and service life of jack, jack are divided into mechanic jacks and hydraulic jack two
Kind, principle has nothing in common with each other, from principle for, hydraulic jack the principle on which is pascal's principle, liquid pressure everywhere
It is by force consistent, in the system of balance, the pressure that smaller piston upper applies is smaller, and apply on big piston
Pressure also than larger, can so keep the static of liquid, so the transmission for passing through liquid, can obtain the difference on different ends
Pressure, can thus reach a purpose for conversion, mechanic jacks use theory of mechanics, back and forth to pull handle, pull out
Pawl is to promote the revolution of ratchet gap, and cone pinion drives large bevel gear, rotates weight lifting screw rod, so that jacking sleeve is risen
Liter declines, and reaches the function of lifting pulling force, and oil pressure oil top inside many at present are all provided with single eccentric wheel, tradition
Eccentric wheel can produce very big noise and vibration when in use, therefore devise a kind of oil pressure oil top guide pillar eccentric wheel.
The content of the invention
For problem above, the invention provides a kind of oil pressure oil top guide pillar eccentric wheel, set by the outside of eccentric wheel
With eccentric slew page guide pillar so that movement track is more precise and stable when in use eccentric wheel, effectively avoid partially
The heart wheel noise occurs with vibration when swinging situations such as, increased the service life of eccentric wheel, improve operating efficiency, be worth pushing away
Extensively.
To achieve the above object, the present invention provides following technical scheme：A kind of oil pressure oil top guide pillar eccentric wheel, it includes gold
Category shell, the metal shell is internally provided with centre bearing, and the centre bearing outside is evenly arranged with guide pillar, the guide pillar
It is connected on metal shell by connecting plate, eccentric slew page is provided with the guide pillar, oily top, center is provided with inside the guide pillar
Bearing includes seamless bearing, and the seamless bearing outside is provided with center oil circuit set, and the center oil circuit set outside passes through oil circuit
Shell fix bar is connected with oil circuit shell, and the oil circuit outer side is provided with guide pillar mounting seat.
Used as a kind of preferred technical scheme of the present invention, the connecting plate is fixed on metal shell by fixed screw.
Used as a kind of preferred technical scheme of the present invention, the guide pillar is provided with the six roots of sensation, angle between adjacent two guide pillars
It is 60 °.
Used as a kind of preferred technical scheme of the present invention, the eccentric slew page two ends are provided with anticreep metallic sheath.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is provided with eccentric slew page guide pillar by the outside of eccentric wheel so that eccentric wheel is taken action rail when in use
Mark is more precise and stable, effectively avoids situations such as occurring noise when eccentric wheel swings with vibration, increased making for eccentric wheel
With the life-span, operating efficiency is improve, be worthy to be popularized.
