Embodiment Construction

[0047] Example 1 of a thin-film feedback throttle module, such as Figure 1-10 As shown, there is a main restrictor and a bypass restrictor, both of which are film feedback restrictors.

[0048] The main restrictor has a first housing, the first housing is composed of a first upper half shell 1 and a first lower half shell 2 fixedly assembled together, the first upper and lower half shells are respectively provided with corresponding positioning connections hole 3, in addition, the first upper half-shell 1 and the first lower half-shell 2 are all provided with annular grooves on the two opposite sides, and the grooves make the corresponding sides of the first upper and lower half-shells form A circular platform, the height of which is lower than the depth of the groove where it is located, so that the circular platforms on the first upper and lower half-shells are relatively non-contact, a first film 4 is arranged between the first upper and lower half-shells, the second The ...

Abstract

The invention relates to a thin film feedback throttling device module, a static bearing module and a main spindle box module. The thin film feedback throttling device module comprises more than two thin film feedback throttling devices; one of the thin film feedback throttling devices is a main throttling device which is fixedly assembled on a spindle box and the other thin film feedback throttling devices are bypass throttling devices which are fixedly arranged on the main throttling device; the shell wall of a shell of the main throttling device is internally provided with an oil supply channel; all the oil supply channels are not communicated; an oil outlet on the main throttling device is adjacently communicated with the corresponding oil supply channel; the oil outlets of the bypass throttling devices which are directly assembled on the main throttling device are adjacently communicated with the corresponding oil supply channels; when the other bypass throttling devices are arranged between one bypass throttling device and the main throttling device at intervals, the oil outlet of the bypass throttling device is in bridged communication with the corresponding oil supply channel; and more than two bridged channels in the same bypass throttling device are not communicated with each other. The thin film feedback throttling device module can be used for solving the problem that pipelines of the throttling device are too many in existing static bearing and main spindle box so that the integration cannot be realized.

Description

technical field [0001] The invention relates to a modular design of a static pressure bearing, in particular to a film feedback throttle module, a static pressure bearing module and a headstock module. Background technique [0002] Hydrostatic bearings are widely used in precision and heavy-duty mechanical equipment due to their advantages such as small friction coefficient, strong load-carrying capacity, high rigidity, and long life. According to the different throttling forms of the throttle, it can be divided into constant throttle and variable throttle. The film feedback throttling hydrostatic bearing belongs to the variable throttle hydrostatic bearing. The hydrostatic bearing is cylindrical. There are at least two pairs (generally two pairs) of symmetrical bearing oil chambers on the inner wall, and the bearing oil chambers of the same pair are symmetrical about the axis of the hydrostatic bearing and connected to the same film feedback restrictor, specifically, the st...
