Description
Technical field
The present invention relates to dismantling technology field, more particularly to a kind of gear shaft bearing disassembling device and method.
Background technology
In mechanical field, gear and bearing are the vital parts of gear drive, in gear-box maintenance process, are
Bearing inspection changes parts and is frequently necessary to dismantle bearing, workman when bearing is dismantled, directly using percussion inner ring or drawing
The method for pulling out inner ring, or generally by the way of shaft shoulder type hydraulic withdrawal, but this method is needed in gear face and bearing
Appropriate gap is left between inner ring end face, such disassembling fixture is inserted into the gap, bearing inner race being limited after hydraulic press pressure
Displacement so as to being dismantled.However, the gear shaft being made of one for gear and axle, and installing positions of bearings and gear position
When closely, because its structure is compacter, the spacing between gear and bearing is smaller, and bearing removal space is smaller, and tooth
Gear ratio bearing shoulder block or bearing inner race on wheel shaft is high, when being dismantled to gear shaft using the above method, it is easier to work
Part causes inevitably infringement, and so as to cause work step cumbersome, high cost, efficiency is low, and labour intensity is big, during investigation failure cause
Between it is long, delay job schedule.
In addition, there is impact unexpected engaging-in and unexpected to nibble out for the engagement of spur gear, and helical gear is nibbled out engaging-in
In circulation, engaging-in the nibbling out of every a pair of gear teeth will not have the mesh impact phenomenon of spur gear gradually, and running and comparing is steady,
So as to ensure that gearratio is constant.Therefore, helical gear can all be used in the mechanism higher to gearratio requirement.And for helical gear
The helical gear shaft being made of one with axle, the bearing removal installed thereon is more difficult, and generally requiring carries out destructive dismounting, or even
Cause bearing to be scrapped in unloading process or occur situations such as axle journal is damaged.
Therefore it provides one kind is more convenient when bearing is dismantled, spoilage during dismounting is reduced, reduced to bearing
The gear shaft bearing disassembling device of damage is extremely important.
The content of the invention
The technical problems to be solved by the invention are how to overcome when dismantle in the prior art helical gear shaft bearing to exist
Dismounting is difficult, and the defect for being easily caused that bearing is scrapped or axle journal is damaged during dismounting etc..
In order to solve the above-mentioned technical problem, the invention provides a kind of gear shaft bearing disassembling device, including ejection piece, top
Plate, connector, internal tooth lamination and clamping element, described ejection piece one end are fixed on top board, and the other end is prominent to internal tooth lamination direction
Go out, and for withstanding one end of gear shaft;It is fixedly connected by connector between the top board and internal tooth lamination;The internal tooth is folded
Piece is made up of overlapped at least two chip architecture identical inner blades, and the clamping element is used to clamp the internal tooth lamination;
Internal tooth lamination after clamping can have cogged one end from gear shaft and pass through, and be fixed on gear axle bearing
On inner ring or back-up ring, through when every teeth groove of inner blade cooperated with the gear teeth of gear shaft, the ejection piece acts on tooth
One end of wheel shaft, gear shaft is ejected, and realizes the dismounting of gear shaft and gear axle bearing.
The gear of gear shaft has multiple gear teeth, and the gear teeth are called the gear teeth of gear shaft in the application.
Further, the inner blade has multiple internal tooths, the every tooth form of internal tooth be it is trapezoidal, the tooth form of the internal tooth with
The gear teeth tooth form of gear shaft is engaged.
