专利摘要:
The invention relates to mechanical engineering, in particular to linear air supports. The purpose of the invention is to increase the accuracy of movement of the support. On the flat working surface of the stationary bearing housing for the air linear bearings, the spiral-shaped grooves emanating from the center in the form of a logarithmic spiral with a flat KWM bottom in cross section are made. The bearing housing has a centrally located air inlet. On the periphery of the working surface of the housing there are holes for air exhaust and an annular channel. The number of grooves is preferably odd. At the periphery, the grooves are deaf. Along the length, the grooves can be made with a depth and / or width increasing towards the periphery of the body, and along the arc - with a length of at least 360 °. Air-supporting channels contribute to a uniform distribution of air in the gap between the rear bearing surfaces of the air bearing, which increases the rigidity of the bearing. 5 z.p, f-ly. 3 il. § SO about

The invention relates to a maghi-building, in particular to air-supported linear supports.
The purpose of the invention is to improve the accuracy of movement of the support.
FIG. 1 shows a fixed bearing housing for air bearings, an axial section j in FIG. 2 - the same, an example of execution; in fig. 3- section A-A in FIG. 2
The stationary bearing housing 1 for air linear bearing supports (Fig. 1) comprises a flat ram: barrel surface 2 and a dentally spaced hole 3 for supplying air. On the working surface of the housing 1, the air distribution means is formed in the form of grooves 4 emanating from the center of the spiral-shaped in a logarithmic spiral with a flat bottom 5 in cross section. On the periphery of the working surface of the groove 3 is made deaf. Along the length of the grooves 3, they can be made with a tub and / or width increasing towards the periphery of the body; I The grooves 3 are made along an arc with a length of at least 360,
I In the design and according to FIG. 2: on the working surface 2 of the housing 1: on its periphery there are holes 1b for exhausting air and an annular channel 7 connected with it. To eliminate vibrations in the support | the number of grooves 3 for air distribution should be preferably odd for stability: the positions of the bearing housing are provided with at least three holes 3 for supplying air,
The suction action of the hole 6 and the channel 7 for the exhaust air counteracts the pressure of the compressed air, summed up through the hole 3 and flowing on the working surface 2, Thanks to the combination

Claims (1)
[1]
The proposed fixed bearing housing is particularly suitable for precision linear bearings. Invention Formula
1, A stationary bearing housing for air linear bearings, comprising a flat working surface, a centrally located air inlet, and also means for distributing air over the working surface, so that improving the accuracy of the support, the air distribution means is made in the form of grooves with a flat bottom in the form of a logarithmic spiral with a flat bottom in cross section,
2, The body of claim 1, 1, and l and h a and y, so that the number of grooves is odd,
3, a body according to claims, 1 and 2, characterized in that at the periphery the grooves are made deaf,
4, The body according to PP, 1 and 2, which is due to the fact that, on the working surface of the body, along its periphery, there is a hole for air discharge and an annular channel communicating with it,
5, The body according to PP, 1-4, about the tapering by the fact .- that the grooves along the length are made with increasing
to the periphery of the hull depth and / or width,
6, The body according to PP, 1-5, which is based on the fact that the grooves are made in an arc with a length of at least 360 °,
