Description
Technical field
Thrust washer technical field is the utility model is related to, specially a kind of anti-absorption type thrust washer.
Background technology
Thrust washer (gasket) is the mechanical seal between two objects, generally between two objects preventing by
Pressure, burn into and pipeline expand with heat and contract with cold leakage naturally.Because machining surface can not possibly be perfect, can be filled out using pad
Mend scrambling.Pad is generally made up of flaky material, such as packing paper, rubber, and silicon rubber, metal, cork, felt, neoprene,
Nitrile rubber, glass fibre or plastic polymer (such as polytetrafluoroethylene (PTFE)).The pad of application-specific may contain asbestos.Pad
(washer) it is that a leak (generally in centre) of thin plate (generally round) is typically the load thread fastener for distributing.
Other purposes are as interval, spring (Belleville pad, ripple pad), wear-resistant pad, pre-display device, locking device.Rubber blanket
Circle is also used in tap (valve) to cut off the liquid or gas of flowing.Rubber or silicon spacer can also be used, to reduce fan
Vibration.Usual pad external diameter is twice of internal diameter or so,
Existing thrust washer gasket construction is relatively simple, lacks anti-adsorption structure, it is difficult to meet production requirement.
Utility model content
The purpose of this utility model is to provide a kind of anti-absorption type thrust washer, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of anti-absorption type thrust washer, including only
Shim body is pushed away, the section of the thrust washer body is circle, and the thrust washer body interior is provided with axis hole, the axis hole
Through thrust washer body, the upper and lower surface of the thrust washer body is equipped with annular groove, is gone back on the thrust washer body
Provided with bar-shaped trough, upper and lower surface of the bar-shaped trough annular spread in thrust washer body.
Preferably, the edge on the upper and lower surface of thrust washer body is equipped with circular arc chamfering.
Preferably, axis hole and the thrust washer body is concentric circles, and the edge of the axis hole also is provided with circular arc chamfering.
Preferably, the number of the annular groove is three, is equidistantly distributed between the annular groove, the depth of the annular groove
Spend for 1/5th of thrust washer body thickness.
Preferably, the depth of the bar-shaped trough is a quarter of thrust washer body thickness.
Preferably, connectivity slot is additionally provided between the annular groove, the depth of the connectivity slot is at least 1.5mm.
Compared with prior art, the beneficial effects of the utility model are：A kind of anti-absorption type thrust washer of the utility model,
Structure is novel, by setting annular groove, bar-shaped trough and connectivity slot, effective anti-thrust washer on the upper and lower surface for pushing away shim body
Ontological adsorption theory, ensure to push away the practicality of shim body, while strictly control the working depth of annular groove, bar-shaped trough and connectivity slot,
Guarantee pushes away the intensity of shim body, by setting circular arc chamfering at the edge of axis hole, on the side on the upper and lower surface of thrust washer body
Edge is respectively provided with circular arc chamfering, and optimization processing technology is easy to use, has very high practicality, greatly improves a kind of anti-suction
The use feature of attached formula thrust washer, ensures its using effect and utilization benefit, is adapted to be widely popularized.
