Abstract

The utility model relates to the technical field of transmission mechanism with motive output or motive input, in particular to a burden relief type cantilever transmission mechanism comprising a cantilever extending out of a box body, a bearing seat matched with the cantilever shaft, a bearing, an oil seal seat and a transmission wheel. The transmission wheel can be a belt pulley, a gear or a sprocket wheel. A spigot of the bearing seat is matched with a bearing hole of the box body. The shaft and an inner hole of the bearing seat are in large clearance fit. The transmission wheel is connected with the shaft through a key. The belt pulley is fixed at the left end of the shaft through a pressing plate with a flute. When the utility model works, the bending stress and the shearing force applied on the wheel train can be transmitted to the bearing seat through the bearing and then transmitted to the box body, so that the shaft can not be influenced by the radial stress. The shaft and the matched inner hole of the bearing seat are in large clearance fit, so that the shaft can be a single-stress shaft only transmitting torque. When the utility model does not work, the shaft becomes a static shaft. The utility model has the advantages of simple and practical structure, small size, convenient manufacture, installation and maintenance, low cost, and prolonged service life and improved running precision of the mechanism to the maximum.

Description

Reduction of Students' Study Load formula cantilever driving mechanism
Technical field
The utility model relates to the driving mechanism technical field with motion output or motion input, particularly a kind of Reduction of Students' Study Load formula cantilever driving mechanism.
Background technique
At present, the motion output of various machinery or the motion input end ends that adopt are that the mode of cantilever realizes combining of train and axle head more.This just makes output or input shaft when bearing warping stress, also will bear very big bending moment and shearing stress.Therefore very easily cause the distortion or the early failue of axle, the bearing of back shaft also damages easily.In recent years, some improvement projects at the problems referred to above have also appearred, the for example belt pulley of C6140 lathe spindle and the axle place that matches, a kind of new thinking has just been proposed, adopt a plurality of bearings and middle transition part to come transmitting torque, avoided the lathe spindle cantilever end to bear radially tensile stress and shearing stress.But still there is imperfect part in this mechanism:
1, partial structurtes are complicated.Often changing or dismantling under the situation of belt pulley, for example oil-field oil pumper is often changed belt pulley because will adjust speed ratio, seems pretty troublesome.
2, the requirement of the accuracy of manufacturing of each component is very high, and assembly precision also requires very high, causes manufacture cost to rise.
3, the volume of entire mechanism is bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of to bear warping stress and do not bear the Reduction of Students' Study Load formula cantilever driving mechanism of very big bending moment and shearing stress.
The purpose of this utility model realizes by following technical proposals:
Reduction of Students' Study Load formula cantilever driving mechanism of the present utility model, it is characterized in that by stretching out the outer cantilevered axle of casing, the bearing support that is complementary of cantilevered axle therewith, be installed in the bearing on this bearing support cylindrical, the oil sealing base that is complementary of bearing support therewith, the drive wheel that is connected with bearing support of cantilevered axle is formed therewith, and the seam of described bearing support matches with the bearing hole of casing, and described cantilevered axle is big Spielpassung with the endoporus of the bearing support that is complementary.
Described drive wheel is belt pulley, gear or sprocket wheel.
Described drive wheel is connected with cantilevered axle by key or spline.
Described oil sealing base is installed in the right side of drive wheel.
Belt pulley is fixed on the left end of described cantilevered axle by bolt and lock washer with the pressing plate that has groove.
Reduction of Students' Study Load formula cantilever driving mechanism of the present utility model is when work, flexural stress and shearing stress that cantilevered axle is born are delivered to bearing support via bearing, again the seam by bearing support with Stress Transfer to casing, thereby avoid making axle to be subjected to the interference of complicated radial stress.Because in this structure, cantilevered axle is big Spielpassung with the endoporus of the bearing support that is complementary, therefore, cantilevered axle is not born the single stress axle of complicated radial stress with regard to becoming a transmitting torque.And when not working in mechanism, cantilevered axle just becomes has not born the static shaft of any power.
Reduction of Students' Study Load formula cantilever driving mechanism of the present utility model has following distinguishing feature:
1, warping stress is only born down in working order by mechanism, and does not bear the effect of any other external force;
2, simple and practical, volume is little, and the manufacturing installation and maintenance is all very convenient;
3, with low cost, but mechanism's life-span and running precision are to maximize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Given embodiment further specifies embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, Reduction of Students' Study Load formula cantilever driving mechanism of the present utility model, it is characterized in that by the cantilevered axle 1 of stretching out outside the casing 7, the bearing support 2 that is complementary of cantilevered axle 1 therewith, be installed in the bearing 5 on these bearing support 2 cylindricals, the oil sealing base 3 that is complementary of bearing support 2 therewith, the drive wheel 4 that is connected with bearing support 2 of cantilevered axle 1 is formed therewith, the seam of described bearing support 2 matches with the bearing hole of casing 7, and described cantilevered axle 1 is big Spielpassung with the endoporus of the bearing support 2 that is complementary.
Described drive wheel 4 is belt pulley, gear or sprocket wheel.Shown in the embodiment of Fig. 1 is belt pulley.
Described drive wheel 4 is connected with cantilevered axle 1 by key or spline.
Described oil sealing base 3 is installed in the right side of drive wheel 4.
Drive wheel is fixed on the left end of described cantilevered axle 1 by bolt and lock washer with the pressing plate 6 that has groove.
Reduction of Students' Study Load formula cantilever driving mechanism of the present utility model is when work, flexural stress that cantilevered axle is born and shearing stress are delivered to bearing support 2 via bearing 5, again the seam by bearing support 2 with Stress Transfer to casing 7, thereby avoid making axle 1 to be subjected to the interference of complicated radial stress.Because in this structure, cantilevered axle 1 is big Spielpassung with the endoporus of the bearing support 2 that is complementary, therefore, cantilevered axle is not born the single stress axle of complicated radial stress with regard to becoming a transmitting torque.And when not working in mechanism, cantilevered axle just becomes has not born the static shaft of any power.
Load reducing type cantalever transmission mechanism of the present utility model has following distinguishing feature:
1, mechanism is in working order lower only bears distorting stress, and does not bear the work of any other external force With;
2, simple and practical, volume is little, and the manufacturing installation and maintenance is all very convenient;
3, with low cost, but mechanism's life-span and running precision are to maximize.
