Abstract

The utility model relates to a BS speed reducer. The BS speed reducer comprises an input shaft, an input shaft cover, a clearance adjusting screw, a reducer body, a fixing plate, a drive plate, balls, an output shaft, and an output shaft cover. The BS speed reducer is characterized in that the input shaft, the fixing board, the drive plate, and the output shaft are installed inside the reducer body, S-shaped cycloid grooves which are arranged on both side faces of the fixing plate and the drive plate are matched with S-shaped cycloid grooves arranged on one side of the input shaft cover and the output shaft, the balls are respectively arranged inside the S-shaped grooves between the input shaft cover and the fixing plate, between the fixing plate and the drive plate, and between the drive plate and the output shaft cover, and the input shaft cover is provided with the clearance adjusting screw. The BS speed reducer has the advantages of being compact in structure, small in size, light in weight, free of clearance, low in noise, large in transmission power, and stable and reliable in transmission, and transmission efficiency can reach 88-93%. Due to the fact that differential motions of two groups of the S-shaped cycloids are adopted so as to achieve speed reduction, a traditional speed reduction theory of achieving the speed reduction by changing the number of teeth of a gear or a worm gear is completely changed.

Description

The BS speed reducer
Technical field:
The utility model belongs to mechanical transmission decelerator series product, is a kind of without gear transmission, all adopts S shape cycloid groove ball to be installed as the BS speed reducer of transmission Jie part between each driving component.
Background technique:
Existing mechanical transmission speed reducer, great majority adopt gear or worm drive, to utilize the change gear number of teeth to realize speed change, its gear or worm reduction gear are in the design and installation process, because the factor of driving component machining accuracy, all have certain process gap and affect output accuracy, add that movement process between tooth and the tooth is with the motion of higher pair form, cause that parts easily wear and tear, transmission not steadily, noise is large, output accuracy is poor etc.
Summary of the invention:
The purpose of this utility model is to provide a kind of compact structure, lightweight, volume is little, through-put power is large, just can reach desirable deceleration effect, zero clearance without gear transmission, transmission efficiency is 88-93%, low noise, stable drive is reliable, the speed reducer that output accuracy is high.
Technical solution of the present utility model is such, a kind of BS speed reducer, comprise input shaft, the input shaft-cup, clearance adjusting screw, body, fixed plate, driving plate, ball, output shaft, the output shaft-cup, it is characterized in that installing in the described body input shaft, fixed plate, driving plate and output shaft, described fixed plate and driving plate bi-side are provided with S shape cycloid groove, the S shape cycloid groove that cooperates input shaft-cup and output shaft one side to arrange, described input shaft-cup and fixed plate, fixed plate and driving plate, place ball in the S shape cycloid groove between driving plate and the output shaft-cup, described input shaft is covered with clearance adjusting screw, and described body two ends are screwed input shaft-cup and output shaft-cup; Described ball is installed between input shaft-cup, fixed plate, driving plate, the output shaft in the regular S shape cycloid groove by certain rule; Described input shaft and output shaft are on same straight line, and input shaft and output shaft are designed to hollow.
The utility model has the advantages that compact structure, lightweight, volume is little, through-put power is large, just can reach desirable gearing down effect without gear transmission, the zero clearance, transmission efficiency is 88-93%, low noise, stable drive is reliable, output accuracy is high.
Description of drawings:
Fig. 1 is overall structure half plan view of the present utility model.
Fig. 2 is overall structure sectional view of the present utility model.
In Fig. 1~Fig. 2, input shaft (1), clearance adjusting screw (2), input shaft-cup (3), body (4), fixed plate (5), driving plate (6), ball (7), output shaft-cup (8), output shaft (9).
Embodiment:
Most preferred embodiment of the present utility model is like this, with reference to Fig. 1, shown in Figure 2, this speed reducer is a kind of speed reducer that just can reach desirable gearing down effect without gear transmission, adopt ball as the transmission part that is situated between between each driving component, regulate by the clearance adjusting screw that input shaft covers, so that the S shape cycloid groove close contact on ball and two driving components, again can be along round and smooth rolling in the very regular S shape cycloid groove on two driving components, thereby it is reliable to reach stable drive, low noise, zero clearance, transmission efficiency are 88-93%; Specifically: a kind of BS speed reducer, comprise input shaft, the input shaft-cup, clearance adjusting screw, body, fixed plate, driving plate, ball, output shaft, the output shaft-cup, wherein, described body 4 interior installation input shafts 1, fixed plate 5, driving plate 6 and output shaft 9, described fixed plate 5 is provided with S shape cycloid groove with driving plate 6 bi-side, the S shape cycloid groove that cooperates input shaft-cup 3 and output shaft 9 one sides to arrange, described input shaft-cup 3 and fixed plate 5, fixed plate 5 and driving plate 6, place ball 7 in the S shape cycloid groove between driving plate 6 and the output shaft-cup 8, described input shaft-cup 3 is provided with clearance adjusting screw 2; Described body 4 two ends are screwed input shaft-cup 3 and output shaft-cup 8; Described ball 7 is installed between input shaft-cup 3, fixed plate 5, driving plate 6, the output shaft 9 in the regular S shape cycloid groove by certain rule; Described input shaft 1 and output shaft 9 are on same straight line, and input shaft 1 and output shaft 9 are designed to hollow, in order to the energising ventilation, are adapted to the use of industrial robot and numerical control device.This speed reducer adopts two groups of differential realizations of S shape cycloid to slow down, and has changed traditional deceleration principle of utilizing gear or worm gear number of teeth speed change fully.
