Materials for linear drives
By selectively combining various additives such as carbon fibres and incorporable lubricants with different base polymers, LUVOCOM engineers have succeeded in developing plastics capable of performing their tasks in a broad temperature range and under a wide variety of loads and chemical conditions.
Ultimately, it is essential to avoid the combination of high loads and high rotational speeds leading to plastic deformation of the thread and hence to jamming of the linear drive. Endurance tests with two million cycles at a linear velocity of 50cm/s have revealed a very low level of heating in the plastic spindle nut and practically no abrasion of the metal nut.
Other advantages of these materials for linear drives are the degree of design freedom, the inexpensive parts manufacture using injection moulding, avoidance of expensive mechanical reworking as well as a long service life and absence of maintenance.
