To master the basic principles of speed reducers for speed reducers. Effectiveness of the speed reducer. Transmission ratio. Master reducer installation and other common terminology plays a very important effect on the application of the reducer, not only to pay attention to the specific structure of the reducer, and always pay attention to the components of the reducer, in-depth analysis of the efficacy of the components of the reducer, immediate check maintenance, so that the disc brake hydraulic motor can be more reasonably applied to increase the service life of the reducer.　　

To ensure that the reducer in the regular work, in addition to the drive gear, shaft, bearing composition and box of the product structure design to give sufficient high attention, should also consider for the reducer grease pool refueling. Oil drain. Check the relative height of the oil level. Production processing, disassembly, maintenance and repair, effective selection and design program cover and box seat.　　

1. Inspection hole; In order to check the gearing condition of rotating components and introduce grease into the box, inspection hole should be set in the appropriate part of the box. The inspection hole is located at the top of the top cover, which can simultaneously observe and check the gear meshing part. Usually, the back cover plate of the inspection hole is fixed with screws in the box cover tight.　　

2. Exhaust fan (also known as "natural ventilation cap"); reducer work, the temperature in the box rises, the vapor expansion, the working pressure rises. In order to better randomly discharge the box of heat deformation gas, maintain the box outside the work pressure balance, to avoid grease along the box surface or radial expansion hydraulic seals and other gaps, usually installed in the box top exhaust fan.　　

3. bearing cover; for fixed immovable shaft components of the radial parts and withstand radial load, bearing seat holes on both sides with bearing cover sealability. Bearing cover has three types: tab and embedded. Box selection of hexagonal bolts fixed immovable, outreach shaft bearing cover for buried holes, equipped with sealing devices. The cam bearing cover is characterized by disassembly and assembly. Adjustment of bearings is convenient, but in contrast with the embedded bearing cover, the total number of parts, large specifications, the appearance is not proportional.

4. Positioning pin; in order to ensure that each disassembly cover bearing seat hole production and manufacturing processing accuracy, positioning pin should be installed in the depth of processing bearing hole before, and installed in the cover and the box seat joint edge. Placed in the box vertical two sides of the joint edge, symmetry box should be symmetrical layout to prevent mis-installation.

5. oil surface marking machine; check the relative height of the septic tank oil surface inside the servo swing hydraulic motor, and maintain a moderate amount of oil in the septic tank from time to time. Generally, it is very easy to view in the small box. Install the oil surface marking machine in the position of the oil surface smoothly.　　

6. oil release screw plug; when changing oil, it should be set to discharge waste paint and clean liquid at the bottom of the box seat and the low part of the septic tank. Usually, the use of screw plug blocking put into the oil port. Oil release screw plug and box body connection surface in the middle need to add anti-seepage oil seal.

7. open box screw; in order to better strengthen the actual effect of airtight, usually in the installation of the whole process in the cross-section of the small box brushed with sodium silicate or sealant, and thus in the disassembly of the whole process is usually difficult to open the outer cover, due to close bonding. Thus, usually produce ~2 fillet holes in the appropriate part of the lid coupling tab, and turn to the cylindrical end or flat end opening box screws. Turn the opening box screw can be extended on the box cover. Mixer hydraulic motor can also be no start box screws. When running the cover, use lifting equipment to pry off the box cover. The size of the opening box screws can be the same as the tab coupling ground bolts. It is not difficult to see that the small parts also have greater use, attitude determines everything thus, for the reducer parts can not be underestimated.
