Abstract
Discoed is a small-size pavement roller running speed reducer. A case cover is fixed at an end opening of a case, an input shaft and a first intermediate shaft are supported to holes on the bottom surface of the case through bearings, a second intermediate shaft and an output shaft are supported to holes of the case cover through bearings, and the first intermediate shaft and the output shaft are arranged coaxially. A one-stage gear is fixed on the input shaft, a two-stage gear and a three-stage gear are fixed on the first intermediate shaft, a four-stage gear and a five-stage gear are fixed on the second intermediate shaft, the six-stage gear is fixed on the output shaft, the end of the first intermediate shaft is supported onto an inner hole of the six-stage gear through a bearing, the one-stage gear meshes with the two-stage gear, the three-stage gear meshes with the four-stage gear, and the five-stage gear meshes with the six-stage gear. One-side support and cross support are combined in the pavement roller running speed reducer, and two bearing shafts are reduced as compared with the existing speed reducer, so that the size of the case is reduced, processing cost is lowered and convenience in installation and maintenance can be achieved.
Description
Technical field
The utility model relates to a kind of baby roller driving speed reducer, is a kind of reduction gears mechanism that engine retard is driven road roller that is applicable to.
Background technique
At present road roller drives employed speed reducer with diesel engine or petrol engine power to walking, big, overweight, the defectives such as processing cost is high, installation and maintenance convenience of integral body that have that the reduction gear back shaft is many, the speed reducer casing big, institute takes up space.
Summary of the invention
The purpose of the utility model provides a kind of baby roller driving speed reducer, overcomes that existing structure gear reduction unit gear back shaft is many, the speed reducer casing is big, institute takes up space greatly, integral body is overweight, processing cost is high, the shortcoming of installation and maintenance convenience.
The purpose of the utility model realizes as follows: this speed reducer comprises casing, case lid, input shaft, one of centre, two of centres, output shaft and driving gear; Case lid is fixed on the port of casing; Input shaft passes through bearings on the hole of tank floor with middle one; Two of centres and output shaft pass through bearings on the hole of case lid, middle one and output shaft arranged concentric; Driving gear comprises one-level gear, secondary gear, tertiary gear, level Four gear, Pyatyi gear and the six grades of gears that are in the casing; The one-level gear is fixed on the input shaft, and on one, level Four gear and Pyatyi gear were fixed on middle two in the middle of secondary gear and tertiary gear were fixed on; Six grades of gears are fixed on the output shaft; Middle one end through bearings on the endoporus of six grades of gears, input shaft and middle two opposite sides with output shaft that mediate, the one-level gear meshes with secondary gear; Tertiary gear and level Four gear engagement, Pyatyi gear and six grades of gear engagement.
Between one-level gear and the input shaft, between tertiary gear and middle one, the formation gear shaft is structure as a whole between two of Pyatyi gear and the centres.
The utility model uses one-sided support and string support mutually, has reduced by two supporting axles than existing speed reducer, and the casing volume is reduced, and has reduced processing cost, and installation and maintenance are convenient.
