Background technology
Quick increase along with the engineering mechanical device kind, rotary drilling rig arises at the historic moment, and digs power resources partly in the oil motor of the hydraulic efficiency system of rotary drilling rig revolving of rotary drilling rig, the rotation of oil motor driven gear step-down gear, gear reduction unit drives the drilling rod rotation, thereby realizes rotary operation.In the prior art, the lubricating oil of rotary drilling rig is antiwear hydraulic oil.
The use of rotary drilling rig has improved working efficiency greatly, but the work-ing life of gear reduction unit is extremely short.Lost efficacy through the dissection of gear reduction unit being discovered gear heavy wear, even the broken teeth phenomenon arranged, its major cause is: one, the heterogeneity of the inner hardness in stratum, impact load takes place at any time, the over-all properties of antiwear hydraulic oil does not satisfy this gear train lubricated needs, particularly extreme pressure and antiwear behavior far away; Therefore two, rotary drilling rig is that hydraulic efficiency system and gear train are combined togather, and just requires this lubricating oil can satisfy the need of work of hydraulic efficiency system, satisfies the needs of gear train again.Particularly the lubricated oil viscosity of oil motor is the smaller the better to hydraulic efficiency system, but the lubricated oil viscosity to gear is to be the bigger the better, the gear lubrication oil viscosity is more big, the ability that relaxes impact load is just more big, the ability of anti-load is also more high, and antiwear hydraulic oil of the prior art can't satisfy the requirement of hydraulic efficiency system and gear train simultaneously.
Though, say in theory, can reduce the tooth of gear and the load between the tooth by the size that adds master wheel, will cause gear train very big like this, be unfavorable for the lightweight of engineering mechanical device and the movement of equipment.
Therefore how solve by lubricated, have very important significance the work-ing life of lubricating, prolong this system that the performance of several aspects is combined to satisfy this system.
