Description
Technical field
The utility model relates to road brake system field, is specifically a kind of barrier gate machine core.
Background technology
Banister, also known as car lug, is be specifically designed to feeder connection management equipment road limiting motor-driven vehicle going, has now been widely used in various occasion.Barrier gate machine core is then the critical piece of banister, and it provides power for whole banister.The barrier gate machine core of prior art is made up of motor, multiple belt pulley and many belts, is taken turns by motor-driven belt, and cooperation carries out transmission with many belts, and then drives restrictor bar lifting or whereabouts.But this kind of kind of drive stability is not high, cause restrictor bar occasional in lifting or the process that falls to be shaken, and this barrier gate machine core drive mechanism is complicated, parts are fragile, and fault rate is high, and application life is short.
In order to solve the problem, the present inventor designs a kind of barrier gate machine core, and this case produces thus.
Summary of the invention
In order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of stability high, structure is simple, the barrier gate machine core of long service life.
The utility model solves the technical scheme that its technical problem adopts: a kind of barrier gate machine core, comprise motor and reduction box, reduction box comprises casing, one-level worm screw, second-stage worm, first-stage worm gear, second-stage worm gear and power output shaft is provided with in casing, one end of one-level worm screw connects motor shaft, the other end stretches in casing, first-stage worm gear be arranged on second-stage worm one end and with one-level worm engaging, second-stage worm gear to be arranged on power output shaft and to engage with second-stage worm.
The bottom that described motor is fixed on reduction box keeps left the position of side, and second-stage worm gear is positioned at the middle part of casing, and second-stage worm is positioned at the below of second-stage worm gear, and first-stage worm gear is arranged on the left end of second-stage worm.
Described second-stage worm and power output shaft are all supported in casing by bearing.
The utility model compared with prior art, have the following advantages: the utility model barrier gate machine core coordinates by worm gear and worm screw the transmission carrying out power, whole transmittance process stability is high, and restrictor bar, along with the lifting of the stability of rotation of power output shaft or whereabouts, any jitter phenomenon can not occur; Meanwhile, the utility model barrier gate machine core drive disk assembly is few, and structure is simple, and long service life, repair rate is low, and use cost is low.

detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1-Figure 3: a kind of barrier gate machine core, motor 1 and reduction box 2 is comprised.The bottom that motor 1 is fixed on reduction box 2 keeps left the position of side.Reduction box 2 comprises casing 3, is provided with one-level worm screw 4, second-stage worm 5, first-stage worm gear 6, second-stage worm gear 7 and power output shaft 8 in casing 3.One end of one-level worm screw 4 connect motor shaft and with motor shaft synchronous axial system, the other end stretches in casing 3.First-stage worm gear 6 is arranged on one end of second-stage worm 5 and engages with one-level worm screw 4, and specifically, first-stage worm gear 6 is fixed in second-stage worm 5, first-stage worm gear 6 and second-stage worm 5 synchronous axial system.Second-stage worm gear 7 to be arranged on power output shaft 8 and to engage with second-stage worm 5.Power output shaft 8 is perpendicular to second-stage worm 5, and the output of power output shaft 8 stretches out outside casing 3, and restrictor bar is arranged on the output of power output shaft 8, lifting or whereabouts along with the rotation of power output shaft 8.
Described second-stage worm gear 7 is positioned at the middle part of casing 3, and second-stage worm 5 is positioned at the below of second-stage worm gear 7, and first-stage worm gear 6 is arranged on the left end of second-stage worm 5.Described second-stage worm 5 and power output shaft 8 are all supported on casing 3 by bearing 9.
During work, motor by one-level worm screw 4 by power transmission to first-stage worm gear 6, the rotation of first-stage worm gear 6 drives second-stage worm 5 to rotate, second-stage worm 5 again by power transmission to second-stage worm gear 7, second-stage worm gear 7 outputs power eventually through power output shaft 8.
The utility model barrier gate machine core coordinates by worm gear and worm screw the transmission carrying out power, and whole transmittance process stability is high, and restrictor bar, along with the lifting of the stability of rotation of power output shaft 8 or whereabouts, any jitter phenomenon can not occur; Meanwhile, the utility model barrier gate machine core drive disk assembly is few, and structure is simple, and long service life, repair rate is low, and use cost is low.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its scope protected according to right.
