Abstract
The utility model relates to the technical field of gearboxes, in particular to a two-speed gearbox mainly used for bucket elevators. The gearbox is provided with a box body; a geared pair and an output shaft are mounted in the box body; one end of the output shaft extends out of the box body; a high-speed motor and a low-speed motor are vertically mounted on the box body; a high-speed input shaft of the high-speed motor is in driving connection with the output shaft through the geared pair; and an overrunning coupler is mounted on a low-speed input shaft of the low-speed motor, which is in drive connection with the output shaft through the geared pair. The gearbox has the advantages of simple structure, convenient speed regulation, high operating efficiency, reliable use, and convenient maintenance; and the overrunning clutch mounted on the input shaft of the gearbox is taken as the power source of the bucket elevator.
Description
Technical field
The utility model relates to the gear-box technical field, especially a kind ofly is mainly used in the double speed gear that band drives slowly on the noria.
Background technique
Noria is a kind of continuous conveyor of vertical lifting material, and main feature is: almost do not have feed back and dig the material phenomenon when promoting material, wattless power is little; Expanded reach is wide, and is few to kind, the characteristic requirement of material, not only can promote general powdery, little grainy material, and can promote the bigger material of chiseling property of mill; Operational reliability is good, promotes steadily long service life.Therefore noria is widely used in promoting various material coals, cement, stone, sand, clay, ore or the like.Because material component difference, material weight are different and have or not factor such as chiseling property of mill to require the lifting speed also should be different; When noria needs repairing in addition, also need speed governing, convenient for maintaining; But the power plant gear-box of existing noria is mounted in the top of lift, when carrying out speed governing, need the people to go up the highest point of lift, manual adjustment, make clutch inner ring and the outer ring chucking on the gear-box or separate, realize high speed or low-speed running, speed governing is very inconvenient, and working efficiency is low.
The model utility content
The technical problems to be solved in the utility model is: in order to overcome the gear-box speed governing inconvenience of existing noria, and the inferior problem of inefficiency, the utility model provides a kind of double speed gear.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double speed gear, has casing, gear driving pair and output shaft are installed in the casing, output shaft one end stretches out outside the casing, be vertically installed with high-speed electric expreess locomotive and slowspeed machine on the casing, the high speed input shaft of high-speed electric expreess locomotive is in transmission connection by gear driving pair and output shaft, on the low speed input shaft of slowspeed machine free wheel device is installed, and is in transmission connection by gear driving pair and output shaft.
The beneficial effects of the utility model are: this gear box structure is simple, on the input shaft of gear-box free wheel device is installed, and as the power source of noria, speed governing is convenient, and high working efficiency is used reliable, easy to maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. casing, 2. output shaft, 3. high-speed electric expreess locomotive, 4. slowspeed machine, 5. high speed input shaft, 6. low speed input shaft, 7. free wheel device.
Embodiment
As shown in Figure 1, a kind of double speed gear, has casing 1, gear driving pair and output shaft 2 are installed in the casing 1, output shaft 2 one ends stretch out outside the casing 1, be vertically installed with high-speed electric expreess locomotive 3 and slowspeed machine 4 on the casing 1, the high speed input shaft 5 of high-speed electric expreess locomotive 3 is in transmission connection by gear driving pair and output shaft 2, on the low speed input shaft 6 of slowspeed machine 4 free wheel device 7 is installed, and be in transmission connection by gear driving pair and output shaft 2, described gear driving pair comprises transmission shaft and the intermeshing driving gear that is enclosed within on transmission shaft and the input shaft.
This gear-box is realized speed regulation by high-speed electric expreess locomotive 3 or slowspeed machine 4 runnings, and when running up, free wheel device 7 inner rings on the low speed input shaft 6 of slowspeed machine 4 rotate, and outer ring and inner ring are separated state; When low-speed running, rotate free wheel device 7 outer rings on the low speed input shaft 6 of slowspeed machine 4, and outer ring and inner ring are gripping orientation.
Claims (1)
1. double speed gear, has casing (1), gear driving pair and output shaft (2) are installed in the casing (1), output shaft (2) one ends stretch out outside the casing (1), it is characterized in that: be vertically installed with high-speed electric expreess locomotive (3) and slowspeed machine (4) on the casing (1), the high speed input shaft (5) of high-speed electric expreess locomotive (3) is in transmission connection by gear driving pair and output shaft (2), on the low speed input shaft (6) of slowspeed machine (4) free wheel device (7) is installed, and is in transmission connection by gear driving pair and output shaft (2).
