Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] refer to figure 1 , an air bearing anti-lateral force testing device, including an electromagnet 6, a force sensor 2, a ferromagnet 8, a base 1, a fixing member 9 and a pad 5. The air flotation shaft 7 is set in the air flotation sleeve 3, and the air flotation sleeve 4 is provided outside the air flotation sleeve 3, and the air flotation sleeve 4 is horizontally installed on the block 5 through the fixing part 9, and the iron There are two magnets 8 and they are symmetrically set on the air shaft 7. The electromagnet 6 has two and is installed directly below the ferromagnet 8. The force sensor 2 is installed under the electromagnet 6 and fixed on the base 1. The spacer 5 is fixed on the base 1 .

[0017] The ferromagnet 8 is a pig iron ring. Other ferromagnetic bodies that can be attracted by magnets can also be used.

[0018] The working process of this em...

Abstract

A device for testing a lateral resistance of an air floatation bearing comprises electromagnets, force sensors, iron magnets, a base, a fixing part and a cushion block, wherein the air floatation bearing is embedded in an air floatation sleeve, and an air floatation sleeve seat is arranged outside the air floatation sleeve and horizontally mounted on the cushion block through the fixing part; an air flotation shaft is sleeved with the two symmetrical iron magnets; the two electromagnets are mounted below the iron magnets; the force sensors are mounted below the electromagnets and fixed on the base; and the cushion block is fixed on the base. According to the device, a force load mechanism is not in direct contact with the air floatation bearing, the dynamitic detection is realized, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of air bearing testing, in particular to an air bearing anti-lateral force testing device. Background technique [0002] With the development of science and technology, gas lubrication is often used instead of ordinary mechanical lubrication. Air bearings introduce high-pressure gas into the gap between objects in relative motion to form an air film, avoiding direct contact to achieve frictionless motion. [0003] As a new type of sliding bearing, air bearing has the characteristics of high speed, high precision, low power consumption and long life. Since the air film between the air bearing shaft and the air bearing sleeve is very thin, the processing precision of the components is very high, so the air bearing also has the disadvantages of small load, low rigidity, and poor reliability. [0004] In order to meet the requirements for air bearings in the industrial field, it is necessary to carry out various performa...
