Abstract
Rotor with breather and anti-rotation arrangement for tire calibration arrangements that provides a suitable breather of the axle hub, and, in turn, an improved oil retention thus preventing the premature wear of internal pieces and possible accidents during its operation.
Claims10
A rotor with breather for tire calibration arrangements characterized by a block rotatably mounted on an axle having an internal air duct or passage that is in communication, by means of an internal end, with a pressurized air hose or pipe that is inside a hollow axle or pressurizes the axle interior and carries the pressurized air from an external air reservoir or tank, and, in turn, said internal air duct or passage is in communication, by means of an external end of said axle, with a transfer chamber operatively communicated with respective tire inflation or deflation valves through corresponding pipes, said rotor comprising:
- at least one bearing mounted inside said block and rotatably mounted, together with said block, around said axle by means of at least one rolling bearing;
- and said bearing further comprising a pair of oil traps on a periphery of the bearing, and a pair of breather guide channels being defined within each respective oil trap of the pair of oil traps, said pair of breather guide channels allowing for the communication and guided passage of pressurized air to an outside of the rotor through one of a breather passage or hole defined in a middle portion of said block.
A rotor with an anti-rotation arrangement for tire calibration arrangements characterized by a block rotatably mounted on an axle having an internal air duct or passage in communication, by means of an internal end, with a pressurized air hose or pipe that is inside a hollow axle and carries pressurized air from an external air reservoir or tank and, in turn, said internal air duct or passage is in communication, by means of an external end of said axle, with a transfer chamber that is operatively communicated with respective tire inflation or deflation valves through corresponding pipes, wherein said block comprises an internal part and an external part, and the rotor comprising at least one anti-rotation arrangement housed in said external part of the block;
- a spring held between an internal wall of the external part of the block and an end of said axle, wherein said anti-rotation arrangement comprises:
- at least one anti-rotation seat wherein a first end of said spring sits at said at least one anti rotation seat;
- at least one anti-rotation guide, the other end of said spring sits at said at least one anti rotation guide;
- at least one solid seal housed in said anti-rotation guide and kept airtight between said spring and said end of said axle;
- and
- at least one O-ring seal formed between said anti-rotation guide and said solid seal.
