Abstract
The utility model relates to a Roots blower, which comprises a shell body, a front wallboard, a rear wallboard, a driving rotor set, a driven rotor set, a front bearing, a rear bearing, a gear box, a driving gear, a driven gear, seal and oil seal. The improved key points are in that the right end of the driving rotor set is provided with an oil throwing disc; lubricating oil and an oil cooling device are arranged in the gear box; the driven gear is a straight gear; the fit of the gears and shafts is a conical fit; the seal adopts the framework type rubber oil seal. The utility model adopts the lubricating method of oil throwing and splashing; the blower can not be resulted in oil less operation to burn out the gears and the bearing because of the oil pump accidents and bad oil nozzle installation and oil channel jam; the reliability is enhanced; the assembly and disassembly and the maintenance are convenient.
Description
The utility model relates to a kind of Roots blower, refers in particular to D36 series Roots blower.
Existing D36 series Roots blower, as 360 millimeters of impeller diameters, all there is following point in the blower of length 280350,460 and 600 millimeters:
The design of 1 lubrication system is unreasonable, and it is provided with the outer oil pump of machine, fuel tank.Oil pump is delivered to each lubricant housings with the lubricant oil in the fuel tank, flows back to fuel tank again, forms the circulatory system.This mode needs every typhoon machine to be equipped with the lubricated system that holds of a cover, and has the hidden danger that causes blower fan gear and bearing to burn out because of the oil pump oil-break.
2 blower fan synchromesh gears are helical gear, produce end thrust in the work, break down easily.
3 gears with to cooperate be that cylinder cooperates, gear combines insecure with axle, mainly bear moment of torsion by key, gear is loosening easily, installs and removes also inconvenience.
The purpose of this utility model is to provide a kind of Roots blower.It is with independent lubrication system, good reliability, the blower that mounting or dismounting, easy to adjust are a kind of raisings of boosting, performance is good, in light weight, simple in structure.
The technological scheme that the utility model adopted is, increases the capacity of gear-box, and the right-hand member of power rotor group is provided with disc in gear-box, and splendid attire lubricant oil in gear-box carries out splash lubrication by gear itself and disc.Driven gear is a spur gear, and gear is that circular cone cooperates with cooperating of axle, gear is combined firmly with axle, and be easy to mounting or dismounting.Driving gear is an integrated type, makes to be easy to assembling and adjustment.Base is the steel plate welding, to alleviate complete machine weight.
Below in conjunction with accompanying drawing its structure is further described.
Fig. 1 is a main machine structure schematic representation of the present utility model.
The utility model comprises engine housing (1), front wallboard (2), rear wall plate (3), power rotor group (4), driven rotor group (5), fore bearing (6), rear bearing (7), gear-box (8), driving gear (9), driven gear (10), sealing (11), oil sealing (12), it improves main points is that right-hand member in power rotor group (4) is provided with disc (13), lubricant oil (14) and oil cooler (15) are housed in gear-box (8), said driven gear (10) is a spur gear, gear (9,10) be that circular cone cooperates with cooperating of axle, rubber oil seal with reinforce is adopted in sealing (11).
The utility model has been cancelled the lubricating system of the independent lubrication system of work that former blower is adopted, get rid of the lubricating system that oil splashes and adopt, adopt straight-tooth crop rotation synchromesh gear, gear adopts circular cone to cooperate with cooperating of axle, driving gear adopts integrated type, strengthened the diameter of master and slave axle, base adopts steel structure.
After the utility model adopts such scheme, can not install bad and oil circuit stops up and causes blower fan not have the oil running burning out gear and bearing because of oil pump accident and oil nozzle, boost and bring up to 68.6Kpa by 49Kpa, increased function, reliability is improved, mounting or dismounting, easy to maintenance, simplify the structure, alleviated weight.
Claims (1)
- A kind of Roots blower comprises engine housing (1), front wallboard (2), rear wall plate (3), power rotor group (4), driven rotor group (5), fore bearing (6), rear bearing (7), gear-box (8), driving gear (9), driven gear (10), sealing (11), oil sealing (12), it is characterized in that being provided with disc (13) at the right-hand member of power rotor group (4), lubricant oil (14) and oil cooler (15) are housed in gear-box (8), said driven gear (10) is a spur gear, gear (9,10) be that circular cone cooperates with cooperating of axle, rubber oil seal with reinforce is adopted in sealing (11).
