smaller and lighter than any other couplings.

2. The tooth outer gear is manufactured in crown shape.

1 GER Distinctive Feature 1. With the capacity of handling heavy loads, gear couplings are much smaller and lighter than any other couplings. Noise or vibration is hardly produced even in high speed operation. 2. The tooth outer gear is manufactured in crown shape. So, even when the axial misalignment occurs it provides good operation. 3. The coupling made of SM45C has a good endurance to high speed and peak load. Jac is manufacturing high quality couplings with new design and high quality control according to standard conformable to KS and JS.

2 GER Structure 1. Jac Gear coupling consists of the internal spur gears in its sleeves and the external spur gears with crowned teeth on its hubs, both of which are in mesh when assembled. t the tooth section of the hub, the tooth surface is crowned and the tooth top is rounded in the axial direction in order to prevent interference at the tooth section when they are operated in eccentric condition. 2. If it is properly mounted without any displacement the external tooth comes is contract with the mating internal tooth at the middle of the crowned portion (Ro) and if it is mounted with offset and angular displacement, the former will with the latter at a point distant from the middle of the crowned portion. 3. Misalignment 1 Misalignment : The driving shaft and driven shaft are parallel to each other but not on the same straight line. 2 ngular Misalignment : The driving shaft and driven shaft cross to each other but not on the same straight line. 3 Composite Misalignment : The driving shaft and driven shaft do not cross to each other nor are they parallel to each other. 4 xial Misalignment : The driving shaft and driven shaft are on the same line but the distance between the two shaft varies (The permissible axial Misalignment is ±25% of C) 1 Misalignment 2ngular Misalignment 3 Composite Misalignment 4 xial Misalignment 3

In case of JC-SEM it will be used like (1)or(2). The case such as (5) must be basically avoided except for when shafts are in complex alignment. 2. When JC-SSM are coupled with an intermediate shaft, which requires fixed supports as(3) 3. When JC-SSM is used together with JC-SEM, an inclinable bearing supporting the intermediate shaft must be set up. 4. If the intermediate shaft is inclining state, it causes vibration. 5. For use in high speed revolution, the allowable max. rpm of the coupling can be increased by adjusting the alignment and improving the balance of the coupling sleeves.

4 Lubrication and Handling 1. Lubricant 1 When assembling, pack the coupling and the coupling hub with the recommended grease until their teeth become invisible, and then tightening the reamer bolts, add the grease through the oil plug hole using a grease gun, etc. 2 Every month, or 240 ~ 250 hours after operation, you should supply grease, Every 3 months or 4,000 hours after operation, you should replace grease after you get rid of the deteriorated. 3 The handling range of temperature for grease is from -17 C to 70 C. You choose grease according to the rpm and circumstance. Maker GULF SHELL TEXCO MOBIL Gulf Crown EP#1 lvania EP#1 Multfak EP-1 Mobilux EP-1 Selection Method of 1.
