Linear motion systems involve the movement of components or parts in a precise single axis motion. The part is usually restricted to the single axis for freedom for automation. The complementing guide components often include the profiled rails, racks and pinion and even the sliding contact bearing structures fitted to provide additional support for the part being lifted and the moving elements of the actuating device. The designer’s profile and the axis of movement should be maintained so; otherwise, issues like misalignment and erratic motion will occur. Erratic motion produces undesired vibration and this would affect the overall accuracy of the linear motion systems. Misalignment will lead to shortened life of the actuating device and even premature wear on the moving parts.

Operation of Linear motion Systems

There are various ways of imparting linear motion to home appliances; these would include two categories:

1. Use of the rod-style actuating devices

2. Use of rodless actuators

Rod-style actuating devices can use fluid power, for example, hydraulics and pneumatics or by use of electric-enabled motion like screws and gears. The rodless actuators also can be fluid powered or use electric components like motors. The guide elements must be designed with the correct alignment for performance of the required automation. A common application of linear motion
systems in the modern home would include table lift systems and the security systems.

Security System

Linear motion systems in security appliances will be evident in the operation of the gates which can be remotely controlled; this involves a set of rollers, a lead screw, motor and a set of gears. The excitation of the motor system will actuate the motion of the sets gears which will operate the lead screws. The advancement of the lead screw in a horizontal axis will push the gate across the guide rails enabled by the rollers fitted at the top and bottom between the guide rails and the gate. Remote operation of this security gate system outlines the importance of linear motion systems and its application to the current home systems.

Table Lift Systems

Desk automatization with table lift is an integral kitchenware in current modern homes. The table lift system employs either the scissor-like system or the gear (rack and pinion) system to raise or lower the accessories in consideration. They help ease the work involved in lifting the accessories through various heights in the kitchen setting. Lift tables, considering their application in home system, are made of stainless steel. Lift table system can be operated by hydraulic, pneumatic and screw system. The guideways will include the screw drives, push chains and the hydraulic foot pump. The right application of these table lift systems is critical as misuse of these would lead to accidents. Periodic maintenance will ensure maximum performance of the table lift systems

Involved Costs

Costs mainly associated with the application of linear motion systems in home automation is the costs involved. The costs will encompass the purchase of equipment, components, electricity (running costs) and the installation costs. Another prevalent cost is the maintenance costs as these linear motion systems have to be regularly maintained for best performance. The level of complexity of the system will determine the maintenance cost of the system.

Conclusion

In the design and installation of linear motion systems, it is advisable to ensure proper alignment by use of tools like gauges and the laser systems. A reference axis is usually created and the other components or parts move or are mounted with respect to this axis. Doing so ensures maximum performance of the system and long life of the system.
