■ 500CBX-RVC Outline Drawing

In order to make fully use of RVC type reducer, it is very important to do optimal design of assembly precision, installation method, lubrication.

Please carefully read the following notes.

■ Assembly Precision

The installation of side components of RVC type reducers shall be designed
based on drawing D.1. Poor assembly will cause shaking, noise and tooth gap, etc.

● Figure D.1: RVC series assembly precision

(A is the distance from the center of the speed reducer to the motor center)

■ Assembly Method

· RVC type reducer installed on the supporting parts of standard legend for see figure D.2. When assembly, please be sure to inject the specified amount of grease.
· Figure D.2, figure D.3 shows the "O" type of ring seal position, so please refer to the seal design.
· The structure can not be used "O" ring, please use the form C.3 liquid sealing sealant.

■ Example Of Low Speed Tube Assembly

Low speed tube for protection through the hollow part of the cable and the lubrication grease inside the seal reducer. Figure D.2 is a reference example for the installation of a low speed tube.

■ Output Shaft Bolt Fastening Assembly Example: Figure D.3

■ Central Gear, Input Gear

● Center gear, input gear precision

If the center gear, the input gear's precision is bad, can produce the noise, the tooth gap, therefore needs to carry on the design according to the following
precision.

Table D.4 center gear, the accuracy of the input gear.

■ Output shaft through hole bolt solid assembly, please ask the company related technical personnel.

■ lubrication

· Reducer in the factory is not filled with grease, so in the installation of the reducer, be sure to fill according to the required amount of filling the recommended lubricant.
· Reducer lubricant filling amount accounts for the interior space of the 70~90%, please make sure that there are about 10% of the space is not filled up.
· Please note that the design of reducer installation needs two oil filling hole, need to seal and convenient oil filling, discharge of oil.
· Reducer sealed grease, the general replacement of oil time is about 2000 hours, please regularly check the grease of aging, pollution, and the provisions of replacement time.
