Abstract
The invention relates to a reducer, which comprises a machine shell and a reducing mechanism arranged in the machine shell, wherein the reducing mechanism comprises an output shaft connected with a load; the output shaft can be connected with the machine shell rotationally and comprises a main shaft body and a flange connector which is detachably connected with the end part of the main shaft body; and a plurality of mounting holes for fixing the load are formed on the flange connector. The output shaft of the reducer of the invention adopts the structure in which the flange connector is detachably connected with the main shaft body, thereby saving materials, simplifying the processing process of the output shaft and facilitating the installation and detachment of the output shaft.
Description
Technical field
The present invention relates to a kind of speed reducer.
Background technique
Common gear reduction unit generally includes and the coaxial input shaft of fixedlying connected of motor output shaft, deboost axle, output shaft in the prior art, have on the input shaft and have one-level gearwheel and secondary small gear on one-level small gear, the deboost axle, have the secondary gearwheel on the output shaft, one-level gearwheel and one-level pinion are finished the one-level deceleration, and secondary gearwheel and secondary pinion are finished double reduction.Cutter is fixedly mounted on this output shaft, just is installed on the main shaft of speed reducer as the saw blade of cutting machine, correspondingly should design the structure that is fit to connect saw blade on this output shaft.Prior art is shown in accompanying drawing 7 and accompanying drawing 8, and the end of output shaft has one section external diameter and becomes big adpting flange, and this axle is adding the complex process in man-hour.Because the production of prior art axis all is to adopt the mode of forging to make usually, when this output shaft of processing, at first need choose raw material, progressively remove redundance, not only waste material again according to maximum outside diameter, and forge complex process, and fine finishing is difficulty relatively, and work efficiency is low.
Summary of the invention
The object of the invention provides a kind of speed reducer of not only having saved material but also simplified manufacturing technique.
For achieving the above object, the technical solution used in the present invention is: a kind of speed reducer, comprise casing, be arranged on the reducing gear in the described casing, described reducing gear comprises the output shaft that links to each other with load, described output shaft is rotatably connected on the described casing, the flange connecting head that described output shaft comprises main shaft and removably is connected described main shaft end offers a plurality of mounting holes that are used for fixing load on the described flanged joint.Between described flanged joint and the described main shaft by a plurality of bolton.
Because technique scheme utilization, the present invention compared with prior art has following advantage and effect: the output shaft of speed reducer of the present invention adopts removably structure combining of flanged joint and main shaft, not only can economical with materials, more simplify the processing technology of output shaft, also made things convenient for the output shaft installation and removal.

Embodiment
Be further described to 6 couples of the present invention of accompanying drawing below in conjunction with accompanying drawing 1:
A kind of speed reducer, comprise casing 1, be arranged on the reducing gear in the described casing 1, described reducing gear comprises that rotation respectively is arranged on the input shaft 2 on the casing 1, deboost axle 3, output shaft 4, wherein, input shaft 2 is fixedlyed connected with the output shaft same axis of motor, be set with first small gear 21 on the input shaft 2, be set with the first gear 31 and second small gear 32 on the deboost axle 3, be set with second largest gear 43 on the output shaft 4, first gear 31 is meshed with first small gear 21, second largest gear 43 is meshed with second small gear 32,4 can finish double reduction from input shaft 2 to output shaft when speed reducer turns round.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (2)
1. speed reducer, comprise casing, be arranged on the reducing gear in the described casing, described reducing gear comprises the output shaft that links to each other with load, described output shaft is rotatably connected on the described casing, it is characterized in that: the flange connecting head that described output shaft comprises main shaft and removably is connected described main shaft end offers a plurality of positioning holes that are used for fixing load on the described flanged joint.
