Abstract
The invention relates to a speed reducer with balls, in particular relates to a speed reducer with balls which utilizes the balls for transmission and belongs to the field of transmission machines. The speed reducer mainly comprises a box body, end covers, an input shaft and an output shaft, wherein the end covers are arranged at the two sides of the box body. The speed reducer is characterized by also comprising at least one set of transmission components arranged in the cavity of the box body; the transmission component consists of a rotary wheel shaft, a ball frame, a ball-frame retainer, transmission balls and retaining balls; the input shaft is arranged in the ball frame of the first set of transmission components; and the output shaft is connected on the rotary wheel shaft of the last set of transmission components. The speed reducer has the advantages that the structure is simple, compact and reasonable; the retaining link of a transmission wheel is simplified by utilizing ball transmission, the internal-space utilization ratio is high, the size of the whole machine is greatly reduced, and the same-specific-volume torque and the speed-reducing ratio efficiency are greatly increased; the integrity is strong, the structure is simple and reliable, the mechanism parts are fewer, the repairing is simple and convenient, the lubricating and sealing performances are good; and the type of the speed reducer is enriched and the use range is wide.
Description
Technical field
The present invention relates to a kind of ball reducer, specifically utilize ball to carry out transmission, belong to the gearing field.
Background technique
In all kinds of Machine Design system; The retarder transmission gear shift link that is absolutely necessary; The seriation of existing retarder; Standardization has the various series product that adopt big or small gear graduation, turbine and worm speed change, chain gear speed change, planet wheel speed change, lack principles such as poor tooth speed change, friction variable speed, hydraulic speed-changing respectively.
Existing retarder major defect is: machine self heaviness, and volume is bigger, and transmission process is not steady, and efficient is lower, and it is many to waste energy.Along with the continuous development of mechanical manufacturing field, to the structural type size of retarder require increasingly high.How to make the retarder volume little, in light weight, transmission efficiency is high, and energy-saving and cost-reducing just seeming is even more important.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of ball reducer is provided, can simplify transmission link significantly, thereby reduce volume and weight significantly, increase moment of torsion and life-span.
According to technological scheme provided by the invention; Ball reducer mainly comprises casing, end cap, input shaft and output shaft; Said end cap is installed in the casing both sides, it is characterized in that: comprise also being installed in the endoceliac at least one cover transmitting assemblies of case that said transmitting assemblies comprises runner shaft, ball rack, ball rack retainer, transmission ball and keeps ball; The big end of said ball rack is installed in the runner shaft, and small end is installed in the ball rack retainer; Said ball rack and runner shaft joint are provided with the transmission ball grooves, and the transmission ball is installed in the transmission ball grooves; Said ball rack ball retainer joint is provided with the maintenance ball grooves, keeps ball to be installed in and keeps in the ball grooves; Said input shaft be installed in first the cover transmitting assemblies ball rack in, input shaft is provided with the ball rack joint and is connected ball grooves, in establish the connection ball; Said output shaft is connected on the runner shaft of last cover transmitting assemblies.
Said runner shaft comprises protruding axle and recessed cover, and the diameter of protruding axle is less than the diameter of recessed cover; Join end to end between said at least one cover transmitting assemblies, the protruding axle of last cover transmitting assemblies runner shaft is connected with back one cover transmitting assemblies ball rack.Said input shaft and output shaft support through bearing fixing, and Bearing Installation is in bearing support.Said bearing support is fastened in the casing.Said ball rack retainer is fastened in the casing.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Utilize the ball transmission to simplify the maintenance link of drive wheel, the inner space utilization ratio is high especially, has significantly reduced the complete machine size, has improved the moment of torsion and the reduction speed ratio efficient of the volume of timber on year-on-year basis greatly; Integrity is strong, and is simple and reliable for structure, and mechanism part is few, and repair is easy, and lubrication and seal property is good; Enriched the kind of speed reducer, using scope is extensive.
