Abstract
The invention provides a bearing chamber for a claw type dry vacuum pump, which belongs to the field of machinery manufacturing. The bearing chamber is composed of bearing chamber bodies, first bearings, second bearings, seam allowances, positioning screws, oil feeding grooves, a gear box, oil flingers, an exhausting plate, a driving shaft, a driven shaft and bearing seats, wherein each bearing chamber body is composed of a first bearing, a second bearing and a bearing seat; each seam allowance is arranged on the upper part of the corresponding bearing chamber body; the positioning screws are assembled on the exhausting plate by the seam allowances; the driving shaft and the driven shaft are assembled on two sides symmetrically; the two bearing chamber bodies are arranged in the gear box. One bearing chamber body is internally provided with two coils of bearings including the first bearing and the second bearing which are assembled together in parallel from top to bottom. The oil feeding grooves are formed in outer rings of the bearing chamber bodies and oil thrown by the oil flingers in the gear box enters the bearing chamber bodies by the oil feeding grooves, so that the bearings are lubricated well. The bearings and a seal are immersed into vacuum oil to be lubricated well, the bearings can be lubricated well, a positioning effect can also be realized, and the service life of the pump is prolonged. The bearing chamber for the claw type dry vacuum pump has good market prospect.
Description
Technical field
The present invention relates to a kind of bearing chamber of placing for claw shape dry type vacuum pump mesohigh step bearing, belong to mechanical manufacturing field.
Background technique
Current claw shape dry type vacuum pump mesohigh step bearing mostly is placed on shaft bearing plate, and the shortcoming of using shaft bearing plate is that the oil that got rid of in gear-box can't lubricating bearings, need to carry out fuel feeding with oil feed pump, has strengthened operation easier and the cost of pump, makes the more complicated of equipment change.Therefore, claw shape dry type vacuum pump high voltage terminal bearing lubrication problem becomes the problem that those skilled in the art need to solve.
Summary of the invention
Technical purpose of the present invention is that the applicable claw shape dry type vacuum pump high voltage terminal bearing of a kind of bearing chamber of design is placed on the inside, can make bearing obtain good lubrication and can play positioning action again, solves complicated at present operation.
For realizing above technical purpose, a kind of claw shape dry type vacuum pump of the present invention by the technological scheme of bearing chamber is: bearing chamber, clutch shaft bearing, the second bearing, rim of the mouth, set screw, oil-feed tank, gear-box, disc, exhaustion plate, driving shaft, auxiliary moving axis, bearing support, consist of; Bearing chamber is comprised of clutch shaft bearing, the second bearing, bearing support, and bearing chamber top, with rim of the mouth, is assemblied on exhaustion plate by the rim of the mouth set screw, Yi Bian driving shaft and auxiliary moving axis are symmetrical, respectively assembles one, and two bearing chambers are all in gear-box.Put clutch shaft bearing, the second bearing two dish bearings in a bearing chamber, clutch shaft bearing, the second bearing are assembled together up and down side by side.The bearing chamber outer ring is designed with oil-feed tank, and the oil that in gear-box, disc has got rid of enters into bearing chamber by oil-feed tank, makes bearing obtain good lubrication.
Beneficial effect: a kind of claw shape dry type vacuum pump of the present invention has the following advantages with bearing chamber: changed claw shape dry type vacuum pump mesohigh step bearing and mostly be placed on drawback on shaft bearing plate, make the oil-lubricated bearing got rid of in gear-box, reduced operation easier and the cost of pump, what equipment was become is easier.Having guaranteed that bearing and sealing are immersed in vacuum oil obtains good lubrication, can make bearing obtain good lubrication and can play positioning action again, has increased the working life of pump.There are good market prospects.
The accompanying drawing explanation
Fig. 1 is a kind of claw shape dry type vacuum pump of the present invention bearing chamber structure schematic diagram.By bearing chamber 1, clutch shaft bearing 2, the second bearing 3, rim of the mouth 4, set screw 5, oil-feed tank 6, gear-box 7, disc 8, exhaustion plate 9, driving shaft 10, auxiliary moving axis 11, bearing support 12, formed.
specific implementation method
Below in conjunction with accompanying drawing, a kind of claw shape dry type vacuum pump of the present invention is described further with bearing chamber.
A kind of claw shape dry type vacuum pump bearing chamber of the present invention, be comprised of bearing chamber 1, clutch shaft bearing 2, the second bearing 3, rim of the mouth 4, set screw 5, oil-feed tank 6, gear-box 7, disc 8, exhaustion plate 9, driving shaft 10, auxiliary moving axis 11, bearing support 12; Bearing chamber 1 is comprised of clutch shaft bearing 2, the second bearing 3, bearing support 12, bearing chamber 1 top is with rim of the mouth 4, by rim of the mouth 4 set screws 5, be assemblied on exhaustion plate 9, Yi Bian driving shaft 10 and auxiliary moving axis 11 symmetries are respectively assembled one, two bearing chambers are all in gear-box 7.Put clutch shaft bearing 2,3 liang of dish bearings of the second bearing in a bearing chamber, clutch shaft bearing 2, the second bearing 3 are assembled together up and down side by side.Bearing chamber 1 outer ring is designed with oil-feed tank 6, and the oil that the interior disc 8 of gear-box 7 has got rid of enters into bearing chamber 1 by oil-feed tank 6, makes bearing obtain good lubrication.
