Abstract
The utility model relates to an anti-bending moment mechanism for a transmission shaft, which belongs to the field of mechanical drive design. The anti-bending moment mechanism for a transmission shaft comprises a transmission shaft, which is connected to a base through a bearing in a rotating manner. The base is provided with a supporting seat, which is in the shape of a sleeving pipe, and is coaxially disposed at the transmission shaft in a sleeving manner. One end of the supporting seat is fixedly connected to the base, and the other end is in an overhanging state, and the overhanging end is coaxially connected to a belt wheel or a sprocket wheel in a rotating manner. The belt wheel or the sprocket wheel is fixedly connected to the transmission shaft in a circumferential manner. The anti-bending moment mechanism for a transmission shaft is advantageous in that the supporting seat is adopted to bear radial tensile force, and the transmission shaft can transmit torque normally, and thereby the transmission shaft can be prevented from bending due to the tensile force.
Description
Technical field
The utility model belongs to mechanical transmission design field, is specifically related to a kind of transmission shaft bending resistance square mechanism.
Background technique
The kind of drive more common in machinery with transmission and chain transmission, the common ground of these two kinds of kinds of drive is that in transmission process, belt and chain all need to have certain tension force to exist, with the tension force of transmission be for allow belt apply certain pressure to belt wheel and then utilize belt and belt wheel between frictional force produce moment carry out rotating band wheel shaft, the tension force in chain transmission is in order to make the abundant interlock of chain and sprocket wheel prevent chain releasing.But because the existence meeting of above-mentioned tension force produces a radial force and then transmission shaft is produced to moment of flexure transmission shaft, this moment of flexure can make transmission shaft produce micro-distortion, while causing transmission shaft rotation, produces and beats, and occurs the phenomenon that noise is excessive; Can accelerate the wearing and tearing of oil sealing simultaneously, often occur oil sealing oil leakage phenomenon.
Model utility content
The purpose of this utility model is to provide the transmission shaft bending resistance square mechanism of the moment of flexure that a kind of tension force that can overcome belt or chain produces transmission shaft.
For achieving the above object, the utility model provides following technological scheme: a kind of transmission shaft bending resistance square mechanism, comprise that transmission shaft is rotationally connected by bearing and pedestal, described pedestal is provided with supporting base, described supporting base is sleeve pipe dress and coaxial sleeve is located on transmission shaft, one end of supporting base is fixedly connected with pedestal, and the other end is overhang shape and this projecting end and belt wheel or sprocket coaxiality and is rotationally connected, and described belt wheel or sprocket wheel are circumferentially fixedly connected with transmission shaft.
Technique effect of the present utility model is: adopt supporting base to bear radially tension force, simultaneously transmission shaft again can normal delivery moment of torsion, has avoided transmission shaft to produce bending because of tension force.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the I partial enlarged view of Fig. 1
Embodiment when Fig. 1, Fig. 2 are the utility model and are applied to belt wheel transmission.
Embodiment
As shown in Figure 1, one transmission shaft bending resistance square mechanism, comprise that transmission shaft 11 and pedestal 10 are rotationally connected, described pedestal 10 is provided with supporting base 12, described supporting base 12 is cannula-like and coaxial sleeve is located on transmission shaft 11, one end of supporting base 12 and pedestal 10 are fixedly connected with the other end and are overhang shape and this projecting end and are connected with belt wheel 13 or sprocket wheel 13 coaxial rotation, and described belt wheel 13 is synchronizeed and is rotationally connected with transmission shaft 11.Can find out by reference to the accompanying drawings, first the tension force that belt wheel 13 is subject to can pass profit to supporting base 12, substantially can not produce bending so the strength ratio of supporting base 12 is higher, and therefore belt wheel 13 just can not continue tension force to pass to transmission shaft 11.
As shown in Figure 1, 2, as optimal technical scheme of the present utility model, the center hole of belt wheel 13 is shoulder hole, between the hole section that described shoulder hole diameter is larger and the periphery of supporting base 12, be provided with clutch shaft bearing 15, between the hole section that described shoulder hole diameter is less and transmission shaft 11, be connected by flat key 16.Adopt said structure easily transmission shaft 11, belt wheel 13 and supporting base 12 to be connected in turn, can meet again the drive connection between each parts simultaneously.
As shown in Figure 1, 2, transmission shaft 11 is provided with thread section, is arranged with nut 14 on thread section, and the end face of nut 14 is resisted against on a less side end face, belt wheel 13 apertures.The effect of nut 14 is that belt wheel 13 is carried out to axial limiting.
As shown in Figure 2, as optimal technical scheme of the present utility model, the sidewall that pedestal 10 is gearbox, the input shaft that described transmission shaft 11 is gearbox, one end of described transmission shaft 11 overhangs to gearbox outside; Supporting base 12 is arranged on the outer wall of gearbox, supporting base 12 is plugged in the axis hole arranging on gearbox sidewall, the periphery of supporting base 12 is provided with collar flange 121, the end face of described flange 121 is resisted against on the outer wall of gearbox, described flange 121 is fixedly connected with gearbox outer wall by bolt 19, between the part of supporting base 12 in axis hole and transmission shaft 11, is provided with the second bearing 17 and oil sealing 18.Adopt said structure to make whole mechanism compacter, the part that supporting base 12 is positioned at axis hole has been served as the bearing support of transmission shaft 11, also makes the fixing more firm of supporting base 12 simultaneously.
