Abstract
The invention discloses a vacuum extruder with herringbone gears, comprising a motor, a transmission mechanism and an operating mechanism, wherein the output shaft of the motor is connected with the input shaft of the transmission mechanism, and the output shaft of the transmission mechanism is connected with the operating mechanism. The vacuum extruder is characterized in that at least one pair of transmission gears of the transmission mechanism is the herringbone gears. The above technical scheme has the following technical effects: helical gear transmission in the prior art is characterized by meshing by one pair of gears, but the herringbone gear is characterized meshing by two pairs of gears; under the condition that other technical parameters are constant, driving torque distributed to each pair of gears is lowered by half, thus greatly improving the stressing condition of each pair of gears, improving the service life and lowering the possibility of faults, such as snaggletooth and the like; gear contact ratio is doubled to ensure stable transmission and improve whole machine operation performance. In addition, because the axial dip angles of the herringbone gear on the transmission shaft are same but have different directions, axial force mutually offsets, therefore, the stressing condition of the transmission shaft is improved, and the service life of the bearing is prolonged.
Description
Technical field
The invention belongs to a kind of brickmaking mechanical, be specifically related to the vacuum-extruder that a kind of transmission mechanism adopts herringbone bear.
Background technology
At present, in brickmaking mechanical, with being most widely used of vacuum-extruder.Its transmission mechanism substantially all is to adopt involute helical gear, mainly is that this structure gear engagement registration is big, stable drive, and driving torque is big.But, this travelling gear is because its facewidth direction and power transmission shaft are the oblique mode, in the transferring power process, power transmission shaft is except that bearing peripheral force and radial load, also will bear very big axial force, therefore, the bearing at its two ends is in complicated alternate stress state, excessive axial force also causes the axial float of bearing easily, influences its service life and result of use.In addition, because the vacuum-extruder working condition is abominable, the driving moment that needs is big, often causes gear wear too fast even phenomenon such as fracture takes place, and influences ordinary production.
Summary of the invention
At the problem that prior art exists, the object of the present invention is to provide a kind ofly can both have good transmission performance, improve the strength of gear situation, can eliminate the vacuum-extruder of the axial force of power transmission shaft again.
For achieving the above object, technical scheme of the present invention is as follows: a kind of vacuum-extruder with herringbone bear, comprise motor, transmission mechanism, operating mechanism, motor output shaft connects the transmission mechanism power shaft, the transmission mechanism output shaft connects operating mechanism, and it is characterized in that: the travelling gear of described transmission mechanism is a double helical spurgear.
Adopt the technique effect that technique scheme reached to be: the helical gear transmission of prior art is a pair of gears engaged, and herringbone bear is two pairs of gears engaged, under the constant situation of other technical parameter, the driving torque that is assigned on every pair of gear reduces half, improved the force-bearing situation of every pair of gear greatly, improved service life, reduced such as phenomenon of the failure odds such as broken teeths.And contact ratio and overlap ratio increases and is twice, and makes transmission more steady, has improved the performance of complete machine running.Direction is opposite because the axial inclination angle of the double helical spurgear on its power transmission shaft is identical in addition, and axial force is just in time cancelled out each other, and has improved the force-bearing situation of power transmission shaft, has prolonged the service life of bearing.
Because from the motor to the operating mechanism, its rotating speed differs bigger, transmission mechanism often adopts the multi-stage gear transmission, because the relative processed complex of herringbone bear, cost is higher, therefore can be according to the needs of taking into account cost, and only one-level gear drive in the end, just with on the output shaft adopt the herringbone bear transmission in the gear wheel engaged transmission, because the moment of torsion that this one-level gear drive is transmitted is maximum.All travelling gear all adopts the herringbone bear transmission.
Description of drawings
The present invention is described further below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the transmission mechanism of a kind of vacuum-extruder of the present invention.
The specific embodiment
The transmission mechanism of the actual vacuum-extruder that uses substantially all is multistage transmission, but for avoiding lengthy and jumbled, conveniently narration, it is the example of one-level transmission to the transmission mechanism output shaft that present embodiment has only provided from motor, multistage transmission reason with it is identical, and those skilled in the art can be in the same way.As shown in Figure 1, motor 7 connects the power shaft 5 of transmission mechanism 1, power shaft 5 is bearing on the casing by bearing 4, be processed with on the power shaft 5 identical and 6, two pinions 6 of two pinions that direction is opposite of axial inclination respectively be positioned at output shaft 2 on two gear wheels 1 be meshed.Output shaft 2 is bearing on the casing by bearing 3, and output shaft 2 is connected with operating mechanism 8, and transmission of power is arrived operating mechanism.Like this, the two pairs of pinions 6 and gear wheel 1 have just constituted the herringbone bear transmission, under the constant situation of other technical parameter, the driving torque that is assigned on every pair of gear reduces half compared to existing technology, improved the force-bearing situation of every pair of gear greatly, improved service life, reduced such as phenomenon of the failure odds such as broken teeths.And contact ratio and overlap ratio increases and is twice, and makes transmission more steady, has improved the performance of complete machine running.Direction is opposite because the axial inclination angle of the double helical spurgear on its power transmission shaft is identical in addition, and axial force is just in time cancelled out each other, and has improved the force-bearing situation of power transmission shaft, has prolonged the service life of bearing.
Above-described only is preferred implementation of the present invention; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
