On.
Copper sheathing is sealed by upper and lower gland and sealing ring, makes lubricating oil in a relatively closed space,
Avoid the pollution and leakage of lubricating oil.
Further, the quantity of guide rod is two.
Further, the quantity of hydraulic cylinder is four, and four hydraulic cylinders are vertically located at the four corners for tearing roller frame bottom surface open, each
Guide rod is located at the centre of corresponding two hydraulic cylinders.
Hydraulic cylinder is distributed in quadrangle, makes to tear roller frame uniform force open, improves the stability of equipment.
Further, stop collar is rectangular.
Stop collar is used into squared design, fixture easy to use is adjusted.
Further, copper sheathing is equipped with lubricating cup.
Lubricating oil can be added from lubricating cup, extend the service life of guide rod.
Further, pressure ring is the ring plate of 42CrMo material.
42CrMo material hardness is high, can use for a long time, and damage is avoided to replace.
Compared with the existing technology, a kind of guide position limiter for bearing block disassembly of the present invention has following excellent
Gesture:
A kind of guide position limiter for bearing block disassembly of the present invention, increases stop collar and lock on the guide bar
Tight nut adjusts adjustable height for fitted bearing seat, can retain last removed position, so that elevation and subsidence mechanical hand be made to reach
Predetermined position remains unchanged, and without frequently adjustment height, goes on smoothly and tears roller open, improves efficiency and disassembly safety.
