Description
Technical field
The utility model relates to a kind of blower fan, is specifically related to a kind of two rotating shaft double-leaf roots blower.
Background technique
Existing Fan Equipment generally includes motor and blower fan, motor and blower fan in one line after through coupling connection for transmission, Fan Equipment takes up space larger; Generally comprise a main shaft in blower fan, blade, intake grill and exhaust outlet, the air output of single shaft list blade blower fan is limited, can not meet the needs of feature occasion; The bearing at fan shaft two ends is through being socketed on the sealings such as labyrinth packing gland in rotating shaft and reinforced seal, labyrinth packing gland Installation and adjustment more complicated, and maintenance is inconvenient; The gear of driving shaft and driven shaft axle head is generally fixed by expansion sleeve, the structure relative complex of expansion sleeve, installs with adjustment inconvenient, and adds the weight of complete machine.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model be to provide a kind of structure simple, maintain twin shaft double-leaf Fan Equipment easily.
For reaching above object, the technological scheme that the utility model is taked is:
A kind of roots blower, comprise shell, the driving shaft be arranged in parallel and driven shaft is provided with in described shell, described driving shaft and driven shaft are all supported in the bearing hole of shell through bearing, described driving shaft and driven shaft are all gone up and are connected with an impeller separately, the input end of described driving shaft is provided with belt pulley, described driving shaft is connected through a gear pair with driven shaft, described driving shaft and driven shaft are conical section with the section of cooperation of gear pair, axle head outside described conical section is provided with outside thread, described outside thread is connected with nut, and described nut pushes against the end face outside in gear pair.
Further, in the enclosure axis bearing bore of described input end bearing and shell between be provided with outside framework oil seal and/or sealing axle sleeve, be provided with seal washer between the bearing in the enclosure axis bearing bore of described output terminal and shell, the bearing in described enclosure axis bearing bore and the shaft part between casing are provided with labyrinth sealing section.
After taking above technological scheme, the beneficial effects of the utility model are:
1. adopt twin shaft double blade structure, driving shaft and driven shaft, by gear pair transmission, realize exporting simultaneously.
2. driving shaft and driven shaft are conical section with the section of cooperation of gear pair, axle and gear interference fit, axle head mounting nuts, and by gear axial restraint, structure is simple, and detachable maintaining is convenient.
3. on axle, directly process labyrinth sealing section replace labyrinth packing gland, reduce the adjustment process in installation process, simple, convenient.
