Description
Technical field
The invention belongs to special-purpose machinery press mounting tool technical field, and in particular to a kind of shaft assembled speed reducer press mounting tool.
Background technology
Gear reducer is speed reduction gearing of the driving link (motor) between working machine, its effect is in prime mover and work
Make to match rotating speed between machine or executing agency and transmit torque, it is a kind of relatively accurate mechanical device, and the purpose is to reduce
Rotating speed, increases torque, using extremely wide in modern mechanical.Wherein shaft assembled speed reducer is motor-driven using work is directly sleeved on
Mounting means on power input shaft, the situation suitable for directly driving working machine (such as belt conveyor) operating.
It is shaft-mounted installing due to being interference fit between shaft assembled speed reducer axle sleeve and working machine power input shaft
Three kinds of methods below generally use during gear reducer：First, being knocked in gear reducer in axis using hammer, copper rod, this method is produced because tapping
Raw plus load, is likely to result in gear reducer inner body and sealing ring damage, transmission accuracy decline, and axis is even caused when serious
Fracture, and it is time-consuming, it is difficult to install.Second, gear reducer is pressed using hydraulic pressure or electronic press-loading device, this method effect
Rate is high, laborsaving, but press-loading device is complicated, bulky, and carrying is inconvenient to use, can not be in working machine onsite application.Three
It is the internal thread hole using working machine shaft end, gear reducer is pressed into axis with bolt, nut, gear reducer is being pressed into axis by this method
Usually required when interior between gear reducer axle sleeve and nut plus a press fitting cushion block, manual rotation nut during press fitting, cushion block compresses
And promote gear reducer to be moved to input shaft, as gear reducer is charged stepwise, the frictional force between nut and cushion block continues to increase, behaviour
Making personnel needs the very big strength of expense that gear reducer could be pressed into axis, and operating efficiency is low, labor intensity is big.
