Then install a small grinding head on the lathe tool holder, stop grinding locally for wire cutting, confirm the basic size, and then draw the axial bisector on the machining surface after removal, and use 1. The 0 mm cutting blade is grinded out three layers in the axial direction with a depth of 0. 5mm groove is used for threading process of wire cutting machine again. At the same time, a wheel inner hole sleeve with Gr15 heat treatment hardness of HRC58-62 was processed, and the inner hole size was 0 smaller than the outer hole size. 5mm, the surface roughness reaches Ra0 after cylindrical grinding. 08, the outer diameter is φ 5±0。 005mm, the thickness is different from the wheel thickness, press into the inner hole of the cycloid wheel, and process three pieces with the on-line cutting machine φ The pin hole of 2 is equipped with a pin, and then the lathe is aligned with a four-jaw chuck, with a parallelism of 0. 01mm, concentricity 0. 01mm, grind the inner hole to the standard fit dimension accuracy, remove the pin on the planet hole, and the maintenance is completed.
For places with particularly strict requirements, it is possible to use a CMM or tool microscope to stop detecting the error of the repaired parts. As for the regular inspection of cycloidal pinwheel reducer, it is requested to stop the regular inspection from four aspects: ① Check the concentricity and tightness of the reducer joint to avoid the damage of the equipment under the action of flying torque force. ② Check the basic condition of the reducer, including the device foundation, fixing screws and operation, ensure the balanced movement of the reducer, and adjust the unreasonable center in time.
③ Regularly change the oil, and clean the relevant equipment of the reducer while changing the oil; Check the oil quantity of the reducer to ensure its normal operation. Dismantle the machine for inspection and troubleshooting. First, loosen the connecting screws of the output part and the reduction part, and take out the base separately, so that the output shaft, output shaft pin and base can be inspected separately; Then remove the cycloid gear, eccentric sleeve, needle gear housing and isolating ring at the local part of the reducer; The rest is the input local motor or end cover input shaft. 1) Partial shafting fault of deceleration
Starting from the input part, check whether the motor has shaft displacement, small bearing point or large bearing chamber. If any, repair or replace the parts, which will make the sound of the motor reach normal and the rotor shaft run-out ≤ 0. 01mm, measure the perpendicularity between the motor rotor and the end face of the flange plate with a dial indicator, taking the rotor rotation center as the benchmark, ≤ 0. 035mm, with concentricity ≤ 0. 035mm。 The input shaft and end cover request of the input end are also the same; If it is unqualified, these parts can be loaded into the lathe after alignment, and then the alignment inspection shall be stopped.
1. The bearing of the cycloid pin gear reducer does not rotate. Please check whether the motor is defective, whether the motor or reverse rotation, etc. 2. Check whether the coupling key connection fails. 3. Check whether the eccentric sleeve of the eccentric bearing is damaged, which causes the rotation of the non-moving cycloid. 4. Check the damage of the positioning bearing. 5. Check the wear of the output bearing, etc. If the bearing does not rotate, the reducer should be overhauled and inspected. If any problem is found, change the cleaning method 1 in time. If there is a problem with the motor, first of all, check whether the motor can still rotate, or whether the motor can reverse, and then check whether there is a problem with the power supply of the motor.
