Abstract
The invention relates to the changing of mechanical bearings. The drive part comprises the bearing base and the bearing, a sleeve barrel with one end open and the other closed. It disassembles the bearing base with the bearing from the roller and lays them on the wood horizontally, putting one end of the sleeve barrel at the end surface of the inner ring of the bearing surface, hammering the other end surface of the sleeve barrel. After the cleaning of the bearing base and the bearing, roller can be changed and bearing base installed to the roller. Put the bearing sleeve on the drive shaft after heating the said bearing, putting one end of the sleeve barrel against the end surface of the inner ring, hammering the other end of the sleeve barrel to keep fit. It can alleviate labor, increase maintenance quality and reduce damage rate of the bearing.
Description
Technical field
The utility model relates to the maintenance of work mechanism drive apparatus, relates in particular to a kind of method of changing mechanical bearings.
Background technology
Cold-strip steel is electroplated unit has a large amount of rollers to assemble before maintenance, and the installation quality of bearing and bearing block has directly determined the quality of maintenance construction.At present, the demolition, installation of bearing all use traditional weight directly to hit the method for bearing, and not only labour intensity is big, and wastes time and energy.Simultaneously,, cause the bearing installation quality very different because workmen's technical ability there are differences, and damage of bearings rate height.
Summary of the invention
Technical problem to be solved by this invention is that the existing bearing method of changing wastes time and energy, and damages bearing easily, and a kind of method of changing mechanical bearings is provided.The present invention changes the bearing method can alleviate workman's work load, and improves repair quality, and the damage of bearings rate is low.
The present invention is achieved in that a kind of method of changing mechanical bearings, and driving member mainly comprises bearing block and bearing, and this method also comprises sleeve, and carries out according to following step:
One, whole bearing block of pulling down and the bearing of Qi Nei lie in them on the sleeper from the roller;
Two, sleeve one end is placed the end face of the inner ring of bearing surface;
Three, use sledgehammer strike sleeve other end, can lay bearing;
Four, bearing block and bearing are installed to bearing block on the roller after cleaning;
Five, heat described bearing after, bearing holder (housing, cover) on roller;
Six, sleeve one end is propped up the inner ring end face of bearing, use the sledgehammer strike sleeve other end that bearing is put in place.
The sleeve that above-mentioned replacing mechanical bearings is used is the sealing of an end opening one end, and the openend external diameter of institute's sleeve is not more than the bearing outer ring external diameter, and internal diameter is not less than the bearing inner race internal diameter.
Bearing for smooth dismantlement work mechanical transmissioning piece, the internal diameter of sleeve is less than the bearing inner race internal diameter, and be provided with a bulge loop on the opening end wall of bearing inner race internal diameter and form shape end, rank exceeding, the external diameter of bulge loop is not more than bearing bore diameter, so that described bulge loop can stretch in the hole of bearing inner race, and the end face of bearing inner race leans against on the terrace of stairstepping end of sleeve openings end.
Described sleeve all is a metal, and the sleeve wall thickness is 6-10mm.Given this, for protection sleeve, described sleeve comprises a stiffener that is welded in blind end.
The present invention is being applicable on the described work mechanism driving member; be specially adapted to the cold rolling unit of picture steel mill; plating unit etc. has among the bearing replacing of a large amount of rollers; when installing and remove bearing, utilize sleeve; the hitting power of weight is evenly spread to the bearing inner sleeve end face; thereby protected bearing, improved bearing utilization rate again.Simultaneously, sleeve transmits hitting power effectively, makes that the demolition, installation work of bearing is not only laborsaving but also saves time.
Description of drawings
Provide the specific embodiment of the present invention below in conjunction with accompanying drawing
Fig. 1 is a bearing installation method schematic diagram;
Fig. 2 is a bearing method for dismounting schematic diagram.
The specific embodiment
The present invention is achieved in that
As depicted in figs. 1 and 2, a kind of method of changing mechanical bearings, driving member mainly comprises bearing block 3 and bearing 2, this method also comprises sleeve 1, and carries out according to following step:
One, whole bearing block of pulling down 3 and the bearing 2 of Qi Nei lie in them on the sleeper 5 from the roller 4,
Two, sleeve 1 one ends are placed the end face of the inner ring of 2 on bearing;
Three, use sledgehammer strike sleeve 1 other end, can lay bearing 2;
Four, after bearing block 3 and bearing 2 clean,, can change roller 4 if need, bearing block 3 is installed on the roller 4;
Five, heat described bearing 2 after, bearing 2 is enclosed within on the roller 4;
Six, sleeve 1 one ends are propped up the inner ring end face of bearing 2, use sledgehammer strike sleeve 1 other end that bearing 2 is put in place.
The sleeve 1 that above-mentioned replacing mechanical bearings is used is the sealing of an end opening one end, and the openend external diameter of sleeve 1 is not more than bearing 2 circle external diameters, preferably is not more than bearing 2 inner ring external diameters, and internal diameter is not less than the bearing inner race internal diameter.
When dismantling bearing 2, sleeve 1 stable supporting with bearing 2, the internal diameter of sleeve 1 is less than bearing 2 inner ring internal diameters, and on the opening end wall that exceeds bearing 2 inner ring internal diameters, be provided with a bulge loop and form shape end, rank, the external diameter of bulge loop is not more than bearing 2 internal diameters, so that described bulge loop can stretch in the hole of bearing 2 inner rings, and the end face of bearing 2 inner rings leans against on the terrace of stairstepping end of sleeve 1 openend.
Described sleeve 1 all is a metal, and sleeve 1 wall thickness is 6-10mm.Given this, for protection sleeve 1, described sleeve 1 comprises a stiffener that is welded in blind end.
The present invention is being applicable on the described work mechanism driving member, is specially adapted to the cold rolling unit of picture steel mill, and plating unit etc. has among the bearing replacing of a large amount of rollers.
