Abstract
A large span double output shaft reducer mainly solves the problem that a novel upright oil pumping unit requires a single output shaft and large span solid double output shafts when used, but an existing reducer can not meet the use requirement. The large span double output shaft reducer is characterized in that two chambers are parallelly arranged in a box body, an output shaft, a first transmission shaft and a second output shaft are arranged in sequence in a first chamber and are parallel, a first output shaft, a second transmission shaft and a second output shaft are arranged in sequence in a second chamber and are parallel, the second output shaft penetrates the two chambers, each shaft is provided with a gear or a tooth face, and the adjacent gears or tooth faces or gear and tooth face are meshed with each other. Compared with a traditional mechanism, the large span double output shaft reducer can meet the use requirement when a user requires the single output shaft and the large span solid double output shafts of the reducer.
Description
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of speed reducer of large span double output shaft.
Background technique
Domestic present traditional petroleum extractor is the single action mechanical axis and drives, and used speed reducer is " Z is serial, YN is serial, S is serial " mostly.Although the speed reducer of these traditional petroleum extractors is all fine in quality such as bearing capacity, noise, working life and outward appearances, wherein the soft flank of tooth and Medium Hardness Tooth Surface Gear speed reducer boundary dimension are relatively large, and cost of material is relatively high; And be " single input shaft, Single-end output axle or coaxial both-end output shaft ", can not satisfy " the solid double output shaft of single input shaft, large span " usage requirement of novel vertical petroleum extractor fully.If satisfy above-mentioned requirements, independently " sub-power type " gear-box, and " sub-power type " gear-box is also wanted independent nonstandard design, namely be equivalent to use two large-scale, heavily loaded reduction gear boxes, boundary dimension is larger like this, and structure is not compact, cost increases, and is more uneconomical.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of speed reducer of large span double output shaft, has mainly solved the problem that existing speed reducer can't satisfy " the solid double output shaft of single input shaft, large span " usage requirement of novel vertical petroleum extractor.The technological scheme that the utility model adopts is: a kind of speed reducer of large span double output shaft, comprise casing, parallelly in the casing be provided with two chambers, be provided with successively parallel input shaft, the first transmission shaft, the second output shaft in the first chamber, the second chamber is provided with the first parallel output shaft, second driving shaft, the second output shaft successively, described the second output shaft runs through two chambers, and each axle is provided with gear or the flank of tooth, and described adjacent gear or the flank of tooth or gear, the flank of tooth are intermeshing.
Described input shaft, the first output shaft and the second output shaft are on same level, and input shaft and the first output shaft coaxial line.
The outer surface of described casing is provided with the logical lid of input at the input shaft place, between logical lid of step and input of input shaft roller bearing, tapered roller bearing are installed side by side.
The beneficial effects of the utility model are owing to having adopted brand-new mechanism design, satisfied the user to speed reducer " the solid double output shaft of single input shaft, large span " and usage requirement.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Such as Fig. 1 in conjunction with shown in Figure 2, a kind of speed reducer of large span double output shaft, comprise casing 1, parallelly in the casing 1 be provided with two chambers, be provided with successively parallel input shaft 3, the first transmission shaft 4, the second output shaft 5, the second chambers 6 in the first chamber 2 and be provided with successively the first parallel output shaft 7, second driving shaft 8, the second output shaft 5, described the second output shaft 5 runs through two chambers, each axle is provided with gear or the flank of tooth, and described adjacent gear or the flank of tooth or gear, the flank of tooth are intermeshing.
Described input shaft 3, the first output shaft 7 and the second output shaft 5 are on same level, and input shaft 3 and the first output shaft 7 coaxial lines.
The outer surface of described casing 1 is provided with at input shaft 3 places that input is logical cover 9, roller bearing 10, tapered roller bearing 11 side by side is installed between covering 9 at the step of input shaft 3 with inputting to lead to.
The utility model is concrete use as follows: this motor for speed reducer power is input to input shaft 3 after by pulley decelerates, pass to the second output shaft 5 through gear reduction again, and between the second output shaft 5 and second driving shaft 8, carrying out dynamic branch with transition gear, transition gear will be shunted transmission of power to the first output shaft 7.
The beneficial effect of model utility is: owing to using technique scheme, satisfied the usage requirement of user to speed reducer " the solid double output shaft of single input shaft, large span ".And mechanism's volume is little, lightweight, compact structure, cost are low, long service life; Casing, connect that precision is high, rigidity is high, bearing capacity is high.
