TC Bearing

The TC Bearings are produced with the most recent technology and materials, and as a result, they are able to survive any environment that may be encountered outside. They are offered in a wide variety of forms and dimensions to choose from. Applications that require great speed but only a light load frequently use TCs. There are a few primary characteristics that can be used to differentiate an excellent TC from an average or below-average one.

High-speed light-load type

A high-speed light-load type TC Bearing for Downhole Tool is a rotor designed for use in a MWD that operates at a high speed and can support just a light load. It has a steel body with a high-hardness carboloy metal block that has been fused onto it. Tc bearings can function at high speeds and are utilized in a wide variety of applications, such as turret drills and positive displacement motors. When compared to traditional bearings, it has a lower carrying capacity but a larger capacity for completely discharging its load in the conclusion.

Lubrication through fluid dynamic pressure is the foundation of the Tc bearing's operational philosophy. This indicates that the dynamic pressure of the liquid sheet is greater than that of the surrounding environment. In addition to that, it possesses a liquid film bearing with several edges.

The structure and shape of a bearing need to be optimized before it can successfully carry out the functions for which it was designed. The implementation of a sand transmission groove all the way around the outer ring is one of the most essential approaches to accomplish this goal. Because of this groove, solid particles will be removed, which will result in an improvement to the sand bearing's overall dynamic qualities.

  • Standardization of all types and all sizes of bearing elements

    Standardization of all types and all sizes of bearing elements

    There is a wide range of Bearing elements available, each of which can be utilized for a specific purpose. Ball bearings, radial bearings, and plain surface bearings are just some of the more prevalent types. These are offered in a wide variety of dimensions and contours.

    Plastic, steel, ceramic, or babbitt bi-material may be used in the production of the bearings instead of or in addition to babbitt, depending on the design of the bearing. The most prevalent type of bearings is the ball variety. However, the ABMA standard applies to bearings of a variety of different types as well.

    The ball radial sliding bearings are typically constructed to withstand loads that are applied in a radial direction. They are also frequently utilized in the mechanisms that control locking devices. Steel is the normal material used in the production of this particular type of bearing. There is either a single row or a double row of balls.

    These kinds of bearings are utilized not only in applications that call for high speeds but also have the capacity to manage a diverse assortment of loads. Typically, a rotating shaft acts as their support mechanism.

  • Static property

    Static property

    The performance of the liquid film in its static equilibrium position is what is meant when people talk about the static property of Tc bearing. In addition to that, it takes into account the bearing gap, the liquid film pressure, and the viscosity of the lubricant.

    The pressure value of the liquid film is lowered thanks to the sand transmission groove that is designed to go all the way around the outer ring of a Tc bearing. This characteristic also contributes to an improvement in the rotordynamic behavior.

    The carrying capacity of Tc radial bearings that have a sand transmission groove is only one-fifth of the carrying capacity of the primary structure. The bearing's end discharging capacity is boosted thanks to the sand transmission groove, which is a feature that has shown to be of great use in the process of discharging solid particles.

    In order to explore the dynamic features of the sand transmission groove Tc bearings, we employ six distinct sand transmission grooves as an example. Each groove has the same dimensions, with a perimeter of 1.0897 millimeters and an area of 0.1714 millimeters squared.

  • External environment

    External environment

    The fluid's pressure from the outside is far greater than the dynamic pressure that is exerted by the liquid film inside of a Tc bearing. Because of this, particles in the film are able to be forced into the groove that is the closest to the direction in which the fluid is rotating. However, they are unable to penetrate the component that has the minimal film thickness.

    In order to choose which TC radial bearing offers the greatest value for your money, you need to take into consideration the kind of drilling fluid you will most likely come into contact with, in addition to the kind of solid particles you will come into contact with. All of these things will have an effect on the Tc bearing's carrying capacity.

    There are several different varieties of Tc bearings available for purchase. The initial component is a Tc primary structure bearing. It is comprised of two primary components, the first of which is an inner ring that is mounted on an axle, and the second of which is an outer ring that is coupled to a drill collar.

Dynamic pressure equation

In order to investigate the hydrodynamic behavior of a Tc bearing, an equation known as the "Tc bearing dynamic pressure equation" was developed. An iterative approach is used to compute the bearing's hydrodynamic parameters. [Case in point:] In addition to this, the impact of couple stresses on the nonlinear dynamic behavior of a dynamically loaded bearing is analyzed and explained.

The Tc carrying capacities of two different constructions are compared. Both the fundamental structure and the structure of the sand transmission groove may be found here. In the beginning, an examination of the dynamic pressure that is present in the liquid film of the main structure is carried out. Second, a comparison is made between the fundamental structure and the dynamic pressure that is present in the sand transmission groove Tc sleeve bearing.

It has been demonstrated that the dynamic pressure exerted by the sand transmission groove Tc bearing is lower than that exerted by the primary structure. This is because the outer ring of the Tc bearing does not permit a continuous liquid coating to be present there. This can be explained by this fact. In addition to this, the Tc bearing's sand transmission groove is constructed so that it goes around the bearing's outer ring. As a result, the solid particles can be eliminated with much less effort.
