Abstract
The utility model discloses a speed reducer for a cement mixer, which comprises an input shaft (1), an output shaft (12), a first sun wheel (2), a first planet wheel (3), a second sun wheel (6) and a second planet wheel (7), wherein the input shaft (1) is connected with the first sun wheel (2); the first sun wheel (2) is meshed with the first planet wheel (3); the second sun wheel (6) is meshed with the second planet wheel (7); the first planet wheel (3) is connected with the second sun wheel (6) through a first planet carrier (5); and the second planet wheel (7) is provided with a second planet carrier (9). The speed reducer is characterized in that the second planet carrier (9) is connected with a drum-shaped serrated coupling (10); the drum-shaped serrated coupling (10) is connected with the output shaft (12); and the output shaft (12) is sheathed with a self-aligning bearing (11). The output shaft of the speed reducer is supported by a single point so that the axis of the output shaft can sway, and thereby, the service life of the speed reducer is prolonged.
Description
Technical field
The utility model relates to a kind of deceleration machinery, in particular concrete mixer speed reducer.
Background technique
It all is to lean on the speed reducer outputting power that the tank body that concrete mixer is used rotates, manufacturing reason owing to agitator tank, the axis swing was bigger when its tank body rotated, and the speed reducer of its outfit is common dead axle speed reducer basically, this dead axle speed reducer has double reduction mechanism, after its input shaft and output shaft are installed on the reducer shell, form a kind of rigid construction, have 2 supports, therefore, after tank body rotates, when the axis swing occurring, it is very big that speed reducer output shaft is held wearing and tearing, and output shaft also is easy to damage, also therefore, exist bigger running to interfere to tank body.
Summary of the invention
In view of the deficiency that background technique exists, the technical problems to be solved in the utility model provides a kind of concrete mixer speed reducer of long service life.
For this reason, the utility model adopts following technological scheme to realize: a kind of concrete mixer speed reducer, comprise input shaft, output shaft first sun gear, first planet wheel, second sun gear and second planet wheel, described input shaft is connected with described first sun gear, described first sun gear and the engagement of first planet wheel, described second sun gear and the engagement of second planet wheel, described first planet wheel is connected with described second sun gear by first planet carrier, described second planet wheel is provided with second planet carrier, it is characterized in that described second planet carrier connects crown gear coupling, described crown gear coupling connects described output shaft, is with selfaligning bearing on the described output shaft.
In the utility model, after adopting crown gear coupling and selfaligning bearing, making speed reducer output shaft become single-point supports, therefore, output shaft can be swung along with the axis swing of stirrer tank body, so just reduced wearing and tearing to output shaft influence and selfaligning bearing, the prolongation of very big degree the working life of speed reducer.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this concrete mixer speed reducer, comprise input shaft 1, output shaft 12, first sun gear 2, first planet wheel 3, second sun gear 6 and second planet wheel 7, described input shaft 12 is connected with described first sun gear 2, described first sun gear 2 and 3 engagements of first planet wheel, described second sun gear 6 and 7 engagements of second planet wheel, described first planet wheel 2 is connected with described second sun gear 6 by first planet carrier 5, described second planet wheel 7 is provided with second planet carrier 9, on the housing 13 of speed reducer, be respectively arranged with first gear ring 4 and second gear ring 8, described first gear ring 4 and 3 engagements of first planet wheel constitute the first class reducer structure; Described second gear ring 8 and 7 engagements of described second planet wheel constitute two reduction gear; Described second planet carrier 9 connects crown gear coupling 10, and described crown gear coupling 10 connects described output shaft 12, and 12 are with selfaligning bearing 11 on the described output shaft, and this selfaligning bearing 11 is installed on the housing 13 of speed reducer.Behind input shaft 1 input power, input shaft 1 drives first sun gear 2 and rotates, first sun gear 2 drives first planet wheel 3 and rotates, and first planet carrier 5 that drives first planet wheel 3 rotates, drive second sun gear 6 and rotate, after second sun gear 6 rotates, drive second planet wheel 7 and rotate, second planet wheel 7 drives second planet carrier 9 and rotates, second planet carrier 9 drives crown gear coupling 10 and rotates, and rotates and drive output shaft 12, like this, output shaft 12 becomes single-point to be supported, just can axis swing, therefore, be installed on the transit mixer after, after the agitator tank tank body rotates, as in axis when swing, appear, and then axis swing of output shaft 12, and like this, just reduced the wearing and tearing of output shaft 12, prolonged working life dramatically with selfaligning bearing 11.
Claims (1)
1. concrete mixer speed reducer, comprise input shaft (1), output shaft (12) first sun gears (2), first planet wheel (3), second sun gear (6) and second planet wheel (7), described input shaft (1) is connected with described first sun gear (2), described first sun gear (2) and first planet wheel (3) engagement, described second sun gear (6) and second planet wheel (7) engagement, described first planet wheel (3) is connected with described second sun gear (6) by first planet carrier (5), described second planet wheel (7) is provided with second planet carrier (9), it is characterized in that described second planet carrier (9) connects crown gear coupling (10), described crown gear coupling (10) connects described output shaft (12), is with selfaligning bearing (11) on the described output shaft (12).
