Abstract
The utility model relates to a self-lubrication lifting chain for a pumping unit. The self-lubrication lifting chain consists of a plurality of coupled external chain plates and a plurality of coupled internal chain plates, wherein the coupled external chain plates and the coupled internal chain plates are alternately connected through sleeves and pins, the external chain plates and the pins adopt interference fit, and the internal chain plates and the sleeves adopt the interference fit. The self-lubrication lifting chain is characterized in that outer edges at two sides of the external chain plates and the internal chain plates are arc-shaped, an oil storage sleeve is installed on the sleeve and is provided with an oil filling hole, and a plurality of oil inlets are uniformly distributed at the circumference of the sleeve. The chain has the self-lubrication performance, can be used as the lifting chain for various roller type long stroke pumping units, is safe and reliable and has a long service life.
Description
One, affiliated technical field:
The present invention relates to a kind of chain, especially a kind of pumping unit selflubricating promotes chain.
Two, background technique
At present, various long stroke pumping units are used for promoting sucker rod and ballast box mostly uses wire rope, because the power drum and the crown sheave diameter of long stroke pumping unit are less, wire rope twines curling, stretching on cylinder for a long time continually, the very big weight of carrying makes that wire rope is damaged easily, fractures again, occurs accident reduction of service life again easily, for the pumping unit that overcomes this shortcoming and have uses wide belt, but effect is also undesirable.
Three, summary of the invention
Goal of the invention: for overcome above-mentioned pumping unit with wire rope or wide belt as lifting member have cracky, fracture, shortcoming such as the life-span is short, provide a kind of pumping unit selflubricating of safe and reliable long service life to promote chain.
The invention technological scheme: the pumping unit selflubricating promotes chain and is made of outer plate, inner plate, bearing pin, sleeve, oil storage cover etc.Alternately be formed by connecting successively by paired outer plate of some joints and the paired inner plate of some joints with bearing pin and sleeve, wherein: outer plate and bearing pin are interference fit, sleeve and inner plate are interference fit, bearing pin passes sleeve for being slidingly matched, it is characterized in that: outer plate and inner plate both sides outer rim are in the arc-shaped, its circular arc and pumping unit cylinder or crown sheave circular arc adapt, the oil storage cover is housed on sleeve, form a toroidal cavity between oil storage cover inner arm and the sleeve outer wall, use with deposit lubricant oil, put an oil hole in oil storage, at the some oil inlet holes of sleeve circumference uniform distribution.
Beneficial effect: 1, outer plate and inner plate both sides outer rim are in the arc-shaped, can eliminate vibration when twining with cylinder; 2, dress oil storage cover deposit butter can lubricate sleeve and bearing pin better on the sleeve, increases the service life.
Four, description of drawings:
Fig. 1 is that the pumping unit selflubricating promotes the chain structural drawing.
Fig. 2 is the plan view that the pumping unit selflubricating promotes the chain structural drawing.
Five, embodiment
It is by outer plate 1 that Fig. 1 pumping unit selflubricating shown in Figure 2 promotes chain, inner plate 2, oil storage cover 3, sleeve 4 and bearing pin 5 constitute, alternately be formed by connecting successively by paired outer plate 1 of some joints and the paired inner plate 2 of some joints with bearing pin 5 and sleeve 4, wherein, outer plate 1 is an interference fit with bearing pin 5, inner plate 2 is an interference fit with sleeve 4, bearing pin 5 and sleeve 4 are for being slidingly matched, it is characterized in that: outer plate 1 and inner plate 2 both sides outer rims are in the arc-shaped, its circular arc adapts with its pumping unit cylinder that twines mutually or crown sheave circular arc, oil storage cover 3 is housed on sleeve 4, oil storage is overlapped and is formed a toroidal cavity between 3 inwalls and sleeve 4 outer walls, usefulness with deposit lubricant oil, on oil storage cover 3, an oil hole 7 is arranged, at the some oil inlet holes 6 of sleeve 4 circumference uniform distributions.
