Abstract
The utility model discloses a main shaft protecting sleeve. The main shaft protecting sleeve comprises a sleeve which is integrally cast and mold, wherein an axial hole is formed in the middle part of the sleeve; a wear-proof layer is arranged on the inner wall of the sleeve; an oil filling hole which is through inside and outside is formed in the side wall of the sleeve; a screw plug is arranged at the opening of the oil filling hole; and oil-resistant rubber rings are arranged at the upper end and the lower end of the oil filling hole in the inner wall of the sleeve. The main shaft protecting sleeve is good in wear resistance, firm to assemble and stable to operate.
Description
Technical field
The utility model relates to a kind of main shaft sheath.
Background technique
Bearing can be divided into rolling bearing and sliding bearing.Wherein rolling bearing is the standard piece of relatively commonly using, and has the advantages such as friction factor is low, the resistance of start is little, designs, uses, lubricates, safeguards all very convenient.And sliding bearing has certain advantage than rolling bearing when high speed, heavy duty, highi degree of accuracy and bearing structure need subdivision.The characteristics of sliding bearing are bearing capacity height, good anti-vibration, noise is little, the life-span is long.Sliding bearing needs separately design, and material generally is bearing metal, claims again Babbitt or bronze.Mostly the axle sleeve of the axle sleeve type sliding bearing that uses at present is to adopt the hollow round column body, and the cylinder internal surface is smooth plane, and this structural type serious wear is altered on lubricating oil is a large amount of, causes bearing shortening in working life.The main cause that produces above phenomenon is exactly that the axle sleeve inner surface structure of axle sleeve type sliding bearing is unreasonable, and hardness is low, only has Rockwell (HRC) 20-25, and is not wear-resistant.
Exist sleeve to wear no resistance in the prior art, the repair and replacement difficulty needs after the damage to change sheath integral body, causes maintenance cost to strengthen.
The model utility content
The utility model provide a kind of wear resistance good, install firmly, the main shaft sheath of working stability.
The utility model technical solution problem provides following scheme:
A kind of main shaft sheath, the sleeve that comprises integrated casting, it is characterized in that: the middle part of described sleeve has axis hole, the inwall of described sleeve is provided with wearing layer, the sidewall of described sleeve is provided with the inside and outside oil hole that is communicated with, the oral area of described oil hole is provided with plug screw, and the oil hole upper/lower terminal on the described sleeve lining has oil-resistant rubber ring.
The outer wall middle part of described sleeve is provided with a ring shape baffle plate, and the following table of described ring baffle is provided with the multiple tracks groove.
The utility model is provided with wearing layer at the internal surface of axle sleeve, described wearing layer adopts quenching technical, so that the interior wall tissue of axle sleeve becomes is wear-resisting, hardness can improve greatly, and at axle sleeve oil hole is set and alleviates frictional force, effectively prolong the working life of axle sleeve, and the outer surface at axle sleeve is provided with baffle plate, is provided with limited impression at the lower surface of baffle plate, has improved the soundness of axle sleeve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of main shaft sheath, the sleeve 1 that comprises integrated casting, the middle part of described sleeve 1 has axis hole 2, the inwall of described sleeve 1 is provided with wearing layer 3, the sidewall of described sleeve 1 is provided with the inside and outside oil hole 4 that is communicated with, and the oral area of described oil hole 4 is provided with plug screw 5, and oil hole 4 upper/lower terminals on described sleeve 1 inwall have oil-resistant rubber ring 6.
The outer wall middle part of described sleeve 1 is provided with a ring shape baffle plate 7, and the following table of described ring baffle 7 is provided with multiple tracks groove 8.
