Description

Circular arc groove water lubricating rubber alloy bearing
Technical field
The invention belongs to the mechanical transmission in the mechanical engineering, particularly relate to a kind of water lubriucated bearing device.
Technical background
A few class water lubriucated bearings have been arranged at present, differ from one another, development along with production technology, need improve constantly the performance of water lubriucated bearing, the water lubricating composite rubber bearing that combines with polygon plane than existing Straight Line and Arc groove is invented out in requirement, the water lubricating composite rubber bearing that the Straight Line and Arc groove combines with arc surface, the better bearings such as water lubricating composite rubber bearing that water lubricating composite rubber bearing that the straight line right angle groove combines with arc surface and spiral arc groove combine with the regular polygon plane, but the bearing capacity of existing water lubriucated bearing is less, fretting wear is higher, it is indifferent to drain silt and impurity, and working life is not long.
Summary of the invention
Purpose of the present invention just provides a kind ofly can improve bearing capacity, reduce fretting wear, strengthen the circular arc groove water lubricating rubber alloy bearing of draining silt and impurity ability, increasing the service life.
A kind of circular arc groove water lubricating rubber alloy bearing involved in the present invention is made up of metal or non-metal shell 1 and specific rubber alloy lining cover 2; It is characterized by: on specific rubber alloy lining cover 2, some Straight Line and Arc grooves 3 are arranged, Straight Line and Arc groove 3 is along circumferentially becoming evenly to distribute and the distribution that is in line vertically; Straight Line and Arc groove 3 is made up of circular arc camber 7; The working surface of adjacent straight line arc groove 3 is by circular arc camber 6, circular arc camber 5 and 4 tangent compositions of circular arc camber.
Radius size R according to circular arc groove water lubricating rubber alloy bearing internal diameter A, external diameter B, length C, circular arc camber 6 1, circular arc camber 5 radius size R 2, circular arc camber 4 radius size R 3, circular arc camber 7 radius size R 4Designed the bearing of three class dimension serieses with parameter situations such as groove number t, be respectively: first kind dimension series circular arc groove water lubricating rubber alloy bearing internal diameter A dimensional range is 15mm～300mm, external diameter B dimensional range is 30mm～370mm, the length C dimensional range is 60mm～1200mm, circular arc camber 6 radius size scopes are 0.9mm～105.6mm, circular arc camber 5 radius size scopes are 0.9mm～105.6mm, circular arc camber 4 radius size scopes are 7.5mm～109.4mm, circular arc camber 7 radius size scopes are 0.5mm～63.3mm, and Straight Line and Arc groove 3 numbers are 4～12.
The second class dimension series circular arc groove water lubricating rubber alloy bearing internal diameter A dimensional range is 40mm～300mm, external diameter B dimensional range is 60mm～370mm, the length C dimensional range is 160mm～1200mm, circular arc camber 6 radius size scopes are 2.3mm～105.6mm, circular arc camber 5 radius size scopes are 2.3mm～105.6mm, circular arc camber 4 radius size scopes are 20mm～150.4mm, and circular arc camber 7 radius size scopes are 1.5mm～63.3mm, and Straight Line and Arc groove 3 numbers are 4～12.
The 3rd class dimension series circular arc groove water lubricating rubber alloy bearing internal diameter A dimensional range is 1-1/4inch～8-3/8inch, external diameter B dimensional range is 1-1/4inch～3-1/2inch, the length C dimensional range is 3inch～30inch, circular arc camber 6 radius size scopes are 2.2mm～116.2mm, circular arc camber 5 radius size scopes are 2.2mm～116.2mm, circular arc camber 4 radius size scopes are 19.1mm～169.1mm, circular arc camber 7 radius size scopes are 1.1mm～69.7mm, and Straight Line and Arc groove 3 numbers are 4～12.
Circular arc groove water lubricating rubber alloy bearing involved in the present invention more is easy to generate elastic hydrodynamic lubrication, between transmission shaft and bearing, form the moisture film supporting, reduce fretting wear, have good silt, impurity discharge capacity, than the long service life of similar bearing more than 3 times, user cost is low, only be advantage such as 1/10～1/4 of conventional metals bearing, be applicable to 3000 more (rev/min)～7000 (rev/min) the correlative equipment in engineering field such as high-speed ship, machinery, oil, chemical industry, water conservancy, mine.

Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
Circular arc groove water lubricating rubber alloy bearing involved in the present invention is made up of metal or non-metal shell 1 and specific rubber alloy lining cover 2 as shown in Figure 2.As shown in Figure 1 in the lubricating structure design of specific rubber alloy lining cover 2, adopted become in the circumference even distribution with at the distribution Straight Line and Arc groove 3 that axially is in line, Straight Line and Arc groove 3 quantity can have a plurality of; Straight Line and Arc groove 3 curved surfaces are made up of circular arc camber 7, and the working surface of adjacent straight line arc groove 3 is by circular arc camber 6, circular arc camber 5 and 4 tangent compositions of circular arc camber, and working surface is making progress into equally distributed lubricating structure design week.
The working principle of circular arc groove water lubricating rubber alloy bearing neck bush 2 lubricating structures design: adopt by circular arc camber 6, circular arc camber 5 and the circular arc camber 4 tangent working surfaces of forming, on the one hand, the easier formation elastic hydrodynamic lubrication of such working curved surface forms the moisture film supporting between transmission shaft and bearing; On the other hand, silt and impurity enter into the axle and bearing between surface of contact circular arc camber 4 time, because of the curved surface that connects between this section working curved surface and the groove is respectively circular arc camber 6 and circular arc camber 5, then silt and impurity are easier is excreted to 3 li of Straight Line and Arc grooves by such curved surface.The Straight Line and Arc groove lubricating structure of circular arc is easier to excrete out silt and impurity.
The invention process the circular arc groove water lubricating rubber alloy bearing of multiclass dimension series, the radius size R of bearing bore diameter A, bearing outside diameter B, bearing length C, circular arc camber 6 wherein 1, circular arc camber 5 radius size R 2, circular arc camber 4 radius size R 3, circular arc camber 7 radius size R 4With groove number t specification conditions, see Table as follows:
