In factory automation, gear rack and linear guide rail are often used together; During installation, it is necessary to consider how to align the rack and guide rail. According to the different types of linear guide rail, the corresponding has different installation methods. Linear guide rail is mainly divided into two types: ball guide rail and roller guide rail.
Start with the ball guide rail. The ball guide rail and gear rack are mainly installed in the following ways:
1: Take the bottom surface of the ball guide rail as the installation reference of the rack:
One disadvantage of this installation method is that if two guide rails are placed in parallel and used together, the other guide rail needs to be installed on a boss, and the height of the boss needs to be the same as that of the rack; How to ensure the parallelism of two datum planes is a problem to be considered in machining.
2: The following installation methods are commonly used:
Two ball guides and a rack are placed in parallel.
During installation, it is necessary to ensure the parallelism between the guide rail and the rack.
The installation of roller guide rail and gear rack is simpler, mainly including the following two types:
1: Integrated rack guide rail
The rack is directly processed on the back of the roller guide rail, which eliminates the complicated alignment between the guide rail and the rack during installation.
2: The rack and roller guide rails are separated
When the rack is installed on the back of the guide rail, it can also be used as the guide rail to align the rack with the roller on the back.
