Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0013] Such as figure 1 , figure 2 as well as image 3 As shown, a reducer used for a transmission device for railway station security inspection mainly includes a reducer box base 3, a box cover 17, various accessories, and three gear shafts 9, 10, 11 and two gear shafts installed on the box base 3. Gears 4 and 12, in which the high-speed stage is helical gear, the low-speed stage is straight tooth, and the high-speed stage gear is arranged away from the torque input end, so that the torsional deformation of the shaft under the action of torque and the deformation of the shaft under the action of bending moment The bending deformation can partially offset each other, which can alleviate the phenomenon of uneven load distribution along the tooth width; the three gear shafts 9, 10, 11 are fixedly connected to the box seat 3 through the bearing...

The invention discloses a speed reducer for a security check transmission device for a railway station. The speed reducer for the security check transmission device for the railway station mainly comprises a speed reducer case body, a case cover, various accessories, three gear shafts and two gears, wherein the three gear shafts and the two gears are arranged on the box body, a high speed turbine stage is helical teeth, a low speed turbine stage is straight teeth, the three gear shafts are respectively fixedly connected with a case seat through bearing end covers, the gear I is arranged between the gear shaft I and the gear shaft II, and the gear II is arranged between the gear shaft II and the gear shaft III. The speed reducer for the security check transmission device for the railway station is large in transmission ratio, high in efficiency, large in output torque, low in working oil temperature, small in oil consumption and stable in transmission. Compared with worm transmission, the service life of the speed reducer for the security check transmission device for the railway station is prolonged by 7-8 times.
Description
technical field [0001] The invention belongs to the technical field of speed reducers, and in particular relates to a speed reducer used for a transmission device for safety inspection at a railway station. Background technique [0002] At present, the flow of people in the railway station is increasing year by year, and the necessary security inspection work when entering the station is also aggravated. Therefore, the quality and safety requirements for the security inspection transmission device also need to be improved. As an important component of the security transmission device, the reducer has strict requirements on its transmission performance and efficiency. The present invention aims at the characteristics of the train station security inspection transmission device, improves on the existing reducer, and designs a transmission ratio, high efficiency, large output torque, low working oil temperature, low fuel consumption, and stable transmission. Reducer with long ...
