The following are the general specific steps for adjusting the clearance of ZSC (A) 500 - 33.1 - 4 medium hard tooth surface reducer:
Preparation:
Check the reducer's instruction manual to clarify the relevant requirements and precautions for adjusting the gap of this model reducer.
Cut off the power supply of the reducer and take safety measures, such as a warning for listing to prevent accidental power-on.
Prepare the required tools such as a gauge, a dial, a vernier caliper, a wrench, a screwdriver, etc., as well as possible adjustment gaskets and other components.
Clean the dirt and debris on the surface of the reducer and keep the working area clean.
Measure the original gap:
You can use a feeler gauge to measure the gap between the two teeth, install the gear according to actual use, fix one of the gears so that it cannot rotate, and use a feeler gauge to plug the tooth profile gap from the end face (the other gear can be rotated). The maximum reading of the feeler gauge that can be inserted is the tooth side gap.
You can also use a dial meter to measure the head, use a dial meter to measure the top of the head near the middle section of the movable gear profile, and rotate the movable gear, and the reading of the meter is the side gap of the end face.
Disassembly related components: Detach the necessary housing, end cover and other components according to the structure of the reducer so that they can be observed and operated to the parts where the gap needs to be adjusted. During the disassembly process, pay attention to keeping the removed parts and record their installation location and order for subsequent correct assembly.
Determine the adjustment method: There are the following common adjustment methods.
1. Washer adjustment method: Check whether there are adjustment spacers between the gear and the shaft, and between the bearing and the bearing seat. If so, the gap can be adjusted by increasing or decreasing the thickness of the gasket. Adding the gasket can move the gear outward and increase the gap; reducing the gasket can move the gear inward and reduce the gap. Note that the specifications and quantity of gaskets should meet the requirements of the reducer and non-standard gaskets shall not be matched at will.
