Abstract
The utility model discloses a synchronous transmission shaft mechanism comprising a bearing support, a transmission shaft, an output belt wheel and an input belt wheel, wherein, the bearing support is supported at the two ends of the transmission shaft, and the output belt wheel is arranged at the shaft head of the transmission shaft. The utility model is characterized in that the synchronous transmission shaft mechanism is provided with an independent rigid base, a bearing support is further arranged in the middle of the transmission shaft, and the transmission shaft is provided with the input belt wheel in synchronous transmission connection with a motor. The utility model has the advantages of convenient installation, processing and adjustment, high coaxiality in transmission shaft installation, good system rigidity and high transmission accuracy, and can shorten the shaft diameter and reduce the cost at the same critical rotational speed of the transmission shaft.
Description
[technical field]
The utility model relates to a kind of transmission shaft mechanism, particularly be a kind of Synchronous Transmission axis mechanism that is widely used in Laser Equipment.
[background technique]
At present, the transmission shaft mechanism of many machinery equipments, the Synchronous Transmission axis mechanism of particularly a kind of Laser Equipment (as laser beam cutting machine, Engraving machineslaser), comprise bearing support, transmission shaft, output pulley and input belt wheel, bearing support is provided with two, is supported on the two ends of transmission shaft respectively, the diaxon bearing is installed in respectively on the Laser Equipment working platform, two output pulleys are located at transmission shaft two ends spindle nose, and the input belt wheel also is located at an end of transmission shaft, is connected with electric-motor-driving.The shortcoming that said mechanism exists is: 1. because the diaxon bearing independently is installed on the working platform respectively, so just need that working platform has in a big way, the processing plane of degree of precision (processing trouble, processing cost height), just can make the transmission shaft two ends after the installation have higher coaxality, when guaranteeing the transmission shaft running big vibration can not appear, also have, this mounting type is installed inconvenient, and trouble is regulated, measured to the transmission shaft coaxality after the installation; 2. two bearing supports are supported on the two ends of transmission shaft, because the general length of transmission shaft is longer, so transmission shaft rigidity is not enough, as improve its critical speed of rotation and rigidity, and the diameter of axle that must the overstriking transmission shaft causes waste of material; 3. the input belt wheel is located at an end of transmission shaft, because the transmission shaft diameter of axle is thinner, in the transmission shaft transmission process, the transmission shaft two ends have bigger windup-degree, the output pulley of being located at transmission shaft two ends spindle nose like this just can not guarantee the output synchronism that transmits, and transmission accuracy is not high.
[summary of the invention]
Problem in view of present known technology existence, the technical problems to be solved in the utility model is to be to provide a kind of installation, processing, easy to adjust, transmission shaft is installed the coaxality height, system stiffness is good, transmission accuracy is high, under the same critical speed of rotation situation of transmission shaft, can dwindle the Synchronous Transmission axis mechanism of the diameter of axle, saving cost.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of Synchronous Transmission axis mechanism, comprise bearing support and transmission shaft, bearing support is supported on the two ends of transmission shaft, the two ends spindle nose of described transmission shaft is respectively equipped with output pulley, also be provided with the input belt wheel on the described transmission shaft, it is characterized in that: described Synchronous Transmission axis mechanism has independently rigid base, and described bearing support is fixedly mounted on the rigid base.Also be provided with bearing support in the middle of the described transmission shaft.Described input belt wheel is located in the middle of the described transmission shaft, and is connected with electric-motor-driving.Described transmission shaft is formed by connecting by coupling by left and right sides transmission shaft.
The utlity model has independently rigid base, the utility model as integral installation independently on the equipment work platform, install simply, as long as because independent rigid base satisfies the installation of bearing support, so, this rigid base volume is little, erection space is little, processing easily, the adjusting of its coaxality, measurement easily guaranteed that easily the transmission shaft two ends have higher coaxality after transmission shaft was installed, just big vibration can not occur when transmission shaft turns round like this, and system rigidity is good; In the middle of transmission shaft, be provided with bearing support, can improve system stiffness, improve transmission shaft critical speed of rotation, under the constant situation of transmission shaft critical speed of rotation, can dwindle the diameter of axle, save cost; The input belt wheel is located in the middle of the transmission shaft, be connected with electric-motor-driving, this kind structure has been eliminated the big windup-degree that the transmission shaft two ends produce in the prior art transmission shaft transmission process, makes the output pulley that is located at transmission shaft two ends spindle nose have very high output synchronism, has improved transmission accuracy; Under the situation of not processing on the working platform plane, also can guarantee coaxial accuracy.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the side view of Fig. 1
[embodiment]
As shown in drawings, this Synchronous Transmission axis mechanism, be mainly used in Laser Equipment, as laser beam cutting machine, Engraving machineslaser etc., this Synchronous Transmission axis mechanism comprises rigid base 1, bearing support 4, transmission shaft 5, output pulley 3 and input belt wheel 7, described rigid base 1 usefulness screw is fixedlyed connected with the working platform of Laser Equipment, described rigid base 1 is strip, its upper surface has three place's mounting planes 2, described bearing support 4 is provided with three, be supported on the two ends, the left and right sides and the centre of described transmission shaft 5 respectively, and be fixedly mounted on the mounting plane 2 of above-mentioned rigid base 1, described transmission shaft 5 is formed by connecting by coupling 6 by left and right sides transmission shaft, described output pulley 3 is provided with two, be installed in the two ends spindle nose of described transmission shaft 5 respectively, described input belt wheel 7 is located near on the transmission shaft 5 of middle bearing bracket, is in transmission connection with motor 8.
This Synchronous Transmission axis mechanism is such installment work: the transmission shaft two ends coaxality after at first each part is connected, installs with rigid base is regulated and is finished, then above-mentioned integral body is fixedlyed connected with the working platform of Laser Equipment by rigid base, during work, motor driving drives the input tape wheel, the output pulley that the input belt wheel drives on the spindle nose of transmission shaft two ends does to rotate synchronously output, and this Synchronous Transmission axis mechanism system stiffness is good, transmission accuracy is high.
