Abstract
A hydro-dynamic fluid-bearing assembly constituted by bearing members disposed around a rotary shaft with the interposition of a film of pressure fluid. At least one of the bearing members is subject when the shaft is stopped to the action of a resilient member generating a limited pre-loading strictly necessary for maintaining the assembly in its correct interrelationship, the said resilient means being subject during operation of the shaft to the action of pressure fluid bled from the film of fluid under pressure lying beneath the bearing member and such that the load on the bearing member increases with the pressure of the fluid film.
Claims8
In a hydro-dynamic fluid bearing assembly
- a rotary shaft,
- bearing members disposed around the rotary shaft with the interposition, in operation, of a pressure fluid film,
- a bearing housing for said members,
- a resilient member acting, when the shaft is stationary, on one of the bearing members, so as to produce a limited pre-load on that member, and
- means, operable during use of the assembly, to subject the said resilient means to the action of pressure fluid bled from the film of pressure fluid lying beneath the bearing member so that the loading on the bearing member increases with the pressure of the fluid film as the rotational speed of the shaft increases.
In a hydro-dynamic bearing assembly
- a rotary shaft,
- bearing members arrayed around and in supporting relationship with the shaft through lubricating films,
- a bearing housing accommodating the bearing members,
- each said bearing member being subject to the action of
- a pressure control device, said device comprising
- a resilient member permanently biasing the associated bearing member towards the shaft whereby to pre-load the bearing member even when the shaft is stationary, and
- means, operable only when the shaft is rotating, to subject the said resilient means to the action of pressure fluid bled from the said film of pressure fluid so that the loading on the bearing member increases with the pressure of the fluid film as the rotational speed of the shaft increases.
