Summary of the invention
Technical problem to be solved by this invention is to provide a kind of head roll and speed reducer pacifies dismantling device, overcomes firmly to pound the peace of firmly knocking when current axle and axle sleeve depart from and tear method open, and pacifying to tear open to input/output axle and speed reducer or motor all has practicability.Be specially adapted to installation and the dismounting of motor reduction gearbox and head roll.This device possesses the feature that peace dismounts and mounts entirely, efficiency is high, not hard again fast, is applicable to the field such as supply line, mining machinery.
Above-mentioned purpose of the present invention is realized by such technological scheme: a kind of head roll and speed reducer pacify dismantling device, comprise speed reducer, drive roller shaft, speed reducer is provided with axle sleeve, drive roller shaft and axle sleeve secure fit, described drive roller shaft one end is provided with a tapped hole along axle center, and the connecting end of described speed reducer offers attachment hole, attachment hole position correspondence installs a hold-doun nut, and described hold-doun nut is fixedly connected with axle sleeve.
The tapped hole of described drive roller shaft is internal thread structure, and its length is about the half of head roll shaft length, and described tapped hole initial end is not provided with internal thread.
Described attachment hole is M36 screw.Described hold-doun nut is M36 nut.
A kind of head roll and speed reducer installation method, the axle sleeve of drive roller shaft and speed reducer is carried out contraposition, when described speed reducer is installed, will being connected with the internal thread in drive roller shaft through the hold-doun nut on speed reducer one end attachment hole reserved and the axle sleeve being fixed on speed reducer compared with small screw of a less nut be put.
Described less nut is M27 nut, and described comparatively small screw is M27 screw rod.
A kind of head roll and speed reducer method for dismounting, will unload compared with small screw and less nut when described speed reducer is removed and replace with larger screw rod, larger screw rod screws in hold-doun nut by the attachment hole reserved through speed reducer connecting end.Described larger screw rod is M36 screw rod.
A kind of head roll and speed reducer pacify dismantling device, and this device is for the axle sleeve of creter crane speed reducer and drive roller shaft quick mounting or disengagement.
A kind of head roll of the present invention and speed reducer pacify dismantling device, are the devices of a kind of speed reducer axle sleeve and drive roller shaft quick mounting or disengagement, avoid the conventional peace using brute-force to beat speed reducer to tear method open.Mainly utilize the laborsaving principle in the inclined-plane of screw flight to reach drive roller shaft to be drawn in or eject the object of speed reducer axle sleeve, the conventional peace using brute-force to beat speed reducer is avoided to tear open, a kind of safe, convenient, fast, the peace dismantling device of damage can not be caused to component, and energy-conserving and environment-protective, effectively reliable.

Embodiment
A kind of head roll and speed reducer pacify dismantling device, comprise speed reducer 1, drive roller shaft 2, speed reducer 1 is provided with axle sleeve 7, drive roller shaft 2 and axle sleeve 7 secure fit, described drive roller shaft 2 one end is provided with a tapped hole along axle center, and the connecting end of described speed reducer 1 offers attachment hole 5, attachment hole 5 position correspondence installs a hold-doun nut 6, and described hold-doun nut 6 is fixedly connected with axle sleeve 7.
The tapped hole of described drive roller shaft 2 is internal thread structure, and its length is about the half of drive roller shaft 2 length, and described tapped hole initial end is about in 5mm length distance and is not provided with internal thread.
Described attachment hole 5 is M36 screw.
Described hold-doun nut 6 is M36 nut.
A kind of head roll and speed reducer installation method, the axle sleeve 7 of drive roller shaft 2 and speed reducer 1 is carried out contraposition, when described speed reducer 1 is installed, will being connected with the internal thread in drive roller shaft 2 through the hold-doun nut 6 on speed reducer 1 one end attachment hole 5 reserved and the axle sleeve 7 being fixed on speed reducer 1 compared with small screw 3 of a less nut 4 be put.Described less nut 4 is M27 nut, and described comparatively small screw 3 is M27 screw rod.
A kind of head roll and speed reducer method for dismounting, will unload compared with small screw 3 and less nut 4 when described speed reducer 1 is removed, replace with larger screw rod 8, through the attachment hole 5 that speed reducer 1 connecting end is reserved, be screwed in hold-doun nut 6 by larger screw rod 8.Described larger screw rod 8 is M36 screw rod.
A kind of head roll and speed reducer pacify dismantling device, and this device is used for axle sleeve 7 and drive roller shaft 2 quick mounting or the disengagement of creter crane speed reducer 1.
