Abstract
The utility model provides a scroll vacuum pump. The scroll vacuum pump is provided with an integral pump shell outside, wherein an eccentric main shaft is arranged in the middle inside the scroll vacuum pump, two sides of the eccentric main shaft are respectively provided with double-row angular contact ball bearings, and a corrugated pipe is arranged at the outer side of the eccentric main shaft. The scroll vacuum pump adopts the integral pump shell structure, thus few components are used, the weight is small, the manufacturing cost is low, the daily maintenance and the assembly and disassembly are convenient, the cantilever type eccentric main shaft structure is adopted, compression vortex lines are increased by 1/3, few leakage points exist in scroll plates with the same diameters, the vacuum extremity is high, the double-raw angular contact ball bearings are adopted, the axial and radial rotating gaps can be adjusted, the high-strength corrugated pipe is added to support, thus rotating parts are few, the noise is low, the friction coefficient is small, and the power of a driving motor is correspondingly reduced by 20%.
Description
Technical field
The utility model belongs to field of vacuum, specifically a kind of scroll vacuum pump.
Background technique
Vacuum pump is that a kind of rotary positive-displacement vacuum pump must have fore pump to cooperate can to use and has larger pumping speed to be contained dust and the insensitive industries such as metallurgy, chemical industry, food, electronics plated film that are widely used in of water vapor in the gas to extracting in wider pressure range.The shortcoming of existing vacuum pump is that complex structure, part are many, and manufacture cost is high, and regular maintenance dismounting difficulty is large, adopt through eccentric main axis structure, leakage rate is high, and decrement is little, rotational parts is many, and the large noise of friction factor increases, and needs corresponding increase drive motor power.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of scroll vacuum pump.
A kind of scroll vacuum pump, it is characterized in that its outer installment has the integrated type pump case, the bosom of described scroll vacuum pump is provided with eccentric main axis, and the both sides of described eccentric main axis are respectively arranged with double-row angular contact bal bearing, and the arranged outside of described eccentric main axis has bellows.
Described a kind of scroll vacuum pump is characterized in that an end of described eccentric main axis is connected with the large-torque electrical machine by coupling.
Described a kind of scroll vacuum pump is characterized in that described double-row angular contact bal bearing is separately positioned on the eccentric main axis two ends.
Described a kind of scroll vacuum pump is characterized in that the other end of described eccentric main axis is connected eddy spinner disk and vortex price fixing Spielpassung with angular contact ball bearing with eddy spinner disk.
Scroll vacuum pump of the present utility model, adopt the integrated type pump shell structure, part is few, lightweight, low cost of manufacture, the regular maintenance easy accessibility adopts single swing arm type eccentric main axis structure, the compression vortex filament increase 1/3(same diameter scroll), same diameter scroll leak point is few, and the vacuum limit is high, selects double-row angular contact bal bearing, adjustable axle is to, radial rotating gap, and in addition high-strength bellows supports, and rotational parts is few, and noise is low, friction factor is little, corresponding minimizing drive motor power 20%.
Description of drawings
Fig. 1 is the structural representation of scroll vacuum pump of the present utility model;
Among the figure, 1-integrated type pump case; 2-large-torque electrical machine; 3-eccentric main axis; 4-bellows; 5-eddy spinner disk; 6-vortex price fixing; 7-coupling; 8-double-row angular contact bal bearing.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of scroll vacuum pump of the present utility model, outer installment has the integrated type pump case, and the bosom of scroll vacuum pump is provided with eccentric main axis, the two ends of eccentric main axis are respectively arranged with double-row angular contact bal bearing, and the arranged outside of eccentric main axis has bellows.One end of eccentric main axis is connected with the large-torque electrical machine by coupling, and the other end of eccentric main axis is connected with eddy spinner disk with angular contact ball bearing, and does not run through eddy spinner disk, eddy spinner disk and vortex price fixing Spielpassung, and eddy spinner disk is done deflection and is swung.
After improving, adopts the utility model the integrated type pump shell structure, part is few, volume is little, lightweight, low cost of manufacture, the regular maintenance easy accessibility adopts single swing arm type eccentric main axis structure, the compression vortex filament increase 1/3(same diameter scroll), same diameter scroll leak point is few, and the vacuum limit is high, selects double-row angular contact bal bearing, adjustable axle is to, radial rotating gap, and in addition high-strength bellows supports, and rotational parts is few, and noise is low, friction factor is little, corresponding minimizing drive motor power 20%.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all is included within the protection domain of the present utility model.
