Abstract

The invention discloses a friction pair magnetic field intensity fine adjustment device for magnetofluid lubrication and a using method for the friction pair magnetic field intensity fine adjustment device. The friction pair magnetic field intensity fine adjustment device is used for adjusting a distance between a permanent magnet and the lower surface of a test sample and comprises an outer shellused for fixing the test sample, a containing cavity used for containing a lifting fine adjustment device is formed in the position, below the test sample, of the outer shell, and the lifting fine adjustment device comprises a box body, a box cover and a lead screw mechanism. By adopting the friction pair magnetic field intensity fine adjustment device, a lead screw transmission pair is driven byrotating a handle, epicyclic motion of a lead screw is converted to linear motion of a slider, the lead screw rotates to drive the slider, and then, two inclined wedged blocks are matched with each other to form low pair surface contact to bear the permanent magnet. The friction pair magnetic field intensity fine adjustment device has the characteristics of high stability, high transmission precision and easiness in implementation.

Description

technical field [0001] The invention relates to a device for fine-tuning the magnetic field intensity of a friction pair for magnetic fluid lubrication, more specifically, it relates to a lifting and fine-tuning device that drives a wedge to reciprocate up and down through a screw drive, and is suitable for adjusting the surface of a friction and wear sample. Test bench setup for magnetic field strength. Background technique [0002] Magnetic fluid is also called magnetic liquid, ferrofluid or ferrofluid. Magnetic fluid is a new type of functional material. Due to its simple structure and easy preparation, it has the fluidity of liquid and the magnetism of solid magnetic materials, so its It has broad application prospects in practical engineering. Magnetic fluid is a mixture of magnetic solid particles with a diameter of nanometer scale (diameter below 10nm), base carrier liquid (also called media) and surfactant. Generally, it is composed of micro- or nano-scale ferromagn...
