Being combined, bring great inconvenience to dismounting, have even to take destructive dismounting (such as oxyacetylene metal-cutting etc.), meeting time serious
Damaging main shaft, maintenance difficulty is big, and maintenance cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of quick release axle sleeve, it is possible to countershaft enter with axle sleeve
Row sharp separation, when carrying out the mask work of axle and axle sleeve between axle and axle sleeve under interlocking pattern, reduce as far as possible countershaft with
The damage of axle sleeve, reduces maintenance cost.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of quick release axle sleeve, bag
Including collar bush and bearing block, collar bush includes little inner circle section and big inner circle section, and axle sleeve disassembly mechanism is arranged in big inner circle section, axle
Set disassembly mechanism is provided with push rod, push rod and the axle end thereof contacts in collar bush, and push rod can move up at collar bush axle, push away
The movement of moving axis.
Preferably in scheme, when described collar bush descends in working order, it is provided with auxiliary axle sleeve in big inner circle section, in auxiliary axle sleeve
The internal diameter of footpath inner circle little with collar bush section is identical, and the external diameter of auxiliary axle sleeve is identical with big inner circle section internal diameter.
Preferably in scheme, between described auxiliary axle sleeve outer wall and big inner circle section inwall, it is provided with gasket ring.
Preferably in scheme, described axle sleeve disassembly mechanism includes retainer ring, the internal diameter of retainer ring and the internal diameter of auxiliary axle sleeve
Identical, retainer ring external diameter is more than the external diameter of auxiliary axle sleeve, and retainer ring one end is provided with bearing, and bearing is provided with two handles, and two one or two
Being provided with guide plate between hands, push rod one end is stretched in collar bush through guide plate and bearing.
Preferably in scheme, described guide plate is provided with screwed hole, and push rod is provided with external screw thread, push rod and guide plate it
Between be threaded connection.
This novel provided a kind of quick release axle sleeve, by using said structure, has the advantages that
(1) under pump normal operating conditions, use collar bush to add auxiliary axle sleeve and can make up a complete axle sleeve, it is ensured that pump
Properly functioning, when needs carry out axle sleeve and axle mask work, then can dismantle down auxiliary axle sleeve and gasket ring, utilize little inner circle section
With big inner circle section difference in internal diameters, axle sleeve disassembly mechanism is fixed；
(2) axle sleeve disassembly mechanism can utilize interference fit between retainer ring and big inner circle section, it is achieved to collar bush inwall
Support, reduce the countershaft fastening force of axle sleeve, the axle in then utilizing push rod to promote collar bush, can realize axle and axle sleeve point
From；
Use said structure, it is possible to realize the sharp separation of axle and axle sleeve, simultaneously can be by countershaft in separation process and axle
The infringement of set is down to minimum, it is ensured that the service life of parts.
