introduction：1.Adjustment of lead screw nut clearance Milling machine There is always a gap between the table longitudinal feed screw and the nut，This is also the requirement for the lead screw to move in the nut，however，The size of this gap，The effect on the milling process is relatively large。It is subjected to friction and wear during long milling，The amount of gap will gradually increase。When the fit gap is too large，Lead to Milling machine Level of table

introduction：The reason for the inaccuracy of the feed in the operation of the centerless grinder is that most of the traditional ordinary centerless grinding machines in China use ordinary screw as the feed transmission。Because the lead screw has a gap,It will lead to direct feed will definitely not match the actual feed value。The high precision centerless grinding machine uses ball screw,Error will compare

introduction：1)The size and nature of the torque required to be transmitted and the requirements for the damping function。Such as，Heavy duty transmission for high power，Optional gear coupling；Transmission for severe impact loads or requiring the elimination of torsional vibration of shafting，Couplings with high elasticity such as tyre type couplings can be selected。 2)The working speed of the coupling is high and low and the centrifugal force caused by it is large

introduction：1Traditional gear couplings Traditional gear couplings generally have two structural forms，One is by2The outer tooth bushing and2Composed of an inner tooth ring；The other is by2A coupling is composed，2For a coupling1The intermediate shaft is joined together。Because the inner tooth ring is fixed on the flange or made directly with the flange，And the first kind2The connection of each inner gear ring shall be connected with reamed hole bolts，So traditional teeth

introduction：Abstract:The belt coupling of heat conduction oil pump is the coupling commonly used in heat conduction oil pump products at present。Its advantage is that the coupling of the motor and the coupling of the heat conduction oil pump are connected through a soft leather egg，The concentricity of the pump is not very strict，Secondly, the temperature of the heat conduction oil pump will not be transmitted to the motor through the coupling。 1、Heat conduction oil pump belt coupling is the current heat conduction oil pump products common
