Abstract
The utility model belongs to the field of construction steel bar machining machinery, and particularly relates to a gearbox of a steel bar bender. The gearbox of the steel bar bender comprises a box body, a sealing plate, an input shaft and an output shaft. The output shaft is fixedly connected with a spindle big gear which is meshed with intermediate shaft teeth. A low-speed intermediate gear is fixedly connected with the intermediate shaft teeth. A high-speed intermediate gear is fixedly connected with the intermediate shaft teeth. The input shaft is connected with duplex teeth through splines. The duplex teeth can be meshed with the low-speed intermediate gear or the high-speed intermediate gear after being shifted by a shift fork. The gearbox further comprises a screw rod shaft, wherein the shift fork is in threaded connection with the screw rod shaft. When the screw rod shaft is rotated, the shift fork can be driven to move in a reciprocating mode so as to shift the duplex teeth. When the steel bar bender is equipped with the gearbox, two rotating speeds can be provided. The steel bar bender can be switched between the two rotating speeds conveniently through rotation of the screw rod shaft, and therefore two types of force moments with different sizes can be provided.
Description
Technical field
The utility model belongs to building iron working machine field, is specifically related to a kind of bar bending machine gearbox.
Background technique
Along with social progress, going deep into of urbanization process, social increasing to the demand of building.In order to improve the manufacturing efficiency of building industry, to mechanization, the requirement of automation also improves thereupon.The reinforcing bar processing machine uses very extensive in building industry, and wherein Reinforcing Steel Crooking Machine is one of the most frequently used reinforcing bar processing machine.In the Reinforcing Steel Crooking Machine that uses at present, be all generally output after motor via reducer is slowed down, majority only has single rotating speed.The Reinforcing Steel Crooking Machine rotating speed is too high, can have bending moment problem less than normal, and rotating speed is too low, can make again the Reinforcing Steel Crooking Machine work efficiency on the low side.Single rotating speed Reinforcing Steel Crooking Machine is difficult to accept or reject in the contradiction of bending moment and work efficiency.
Summary of the invention
A kind of bar bending machine gearbox that the utility model provides for above-mentioned deficiency after Reinforcing Steel Crooking Machine equipment gearbox of the present utility model, can provide two kinds of rotating speeds on a Reinforcing Steel Crooking Machine.
The utility model is achieved in that a kind of bar bending machine gearbox, comprise casing, shrouding, input shaft, output shaft, output shaft is fixedly connected with the main shaft gearwheel, main shaft gearwheel and the engagement of jack shaft tooth, the low speed intermediate gear is fixedly connected with the jack shaft tooth, and the high speed intermediate gear is fixedly connected with the jack shaft tooth, input shaft and duplex-gear spline joint, duplex-gear can mesh with low speed intermediate gear or high speed intermediate gear under the stirring of shift fork.Gearbox also comprises screw axis, and shift fork is threaded with screw axis, and the rotary screw rod axle can drive shift fork and move back and forth, thereby stirs duplex-gear.
Reinforcing Steel Crooking Machine can provide two rotating speeds by equipping gearbox of the present utility model.By the rotary screw rod axle, can drive shift fork and move back and forth, make Reinforcing Steel Crooking Machine conversion rotating speed thereby stir duplex-gear.When crooked bar reinforcement needs high-torque, be transformed into bottom gear, in order to improve output torque.When the little reinforcing bar of bending needs little moment, be transformed into top gear, in order to improve speed of production.
Description of drawings
Fig. 1 is the utility model bar bending machine gearbox plan view.
Fig. 2 is that the A-A of Fig. 1 cuts open.
In accompanying drawing: 1-casing, 2-main shaft gearwheel, 3-output shaft, 4-jack shaft tooth, 5-low speed intermediate gear, 6-high speed intermediate gear, 7-duplex-gear, 8-input shaft, 9-shift fork, 10-screw axis, 11-shrouding.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail; but the utility model is not limited to following mode of execution; any change of making on the present embodiment principle or replacement scheme all fall among the claimed scope of the utility model.
By reference to the accompanying drawings 1 and accompanying drawing 2, a kind of bar bending machine gearbox comprises casing 1, shrouding 11, input shaft 8, output shaft 3, output shaft 3 is fixedly connected with main shaft gearwheel 2, main shaft gearwheel 2 and 4 engagements of jack shaft tooth, low speed intermediate gear 5 is fixedly connected with jack shaft tooth 4, high speed intermediate gear 6 is fixedly connected with jack shaft tooth 4, and input shaft 8 and duplex-gear 7 spline joints, duplex-gear 7 can mesh with low speed intermediate gear 5 or high speed intermediate gear 6 under the stirring of shift fork 9.Gearbox also comprises screw axis 10, and shift fork 9 is threaded with screw axis 10, and rotary screw rod axle 10 can drive shift fork 9 and move back and forth, thereby stirs duplex-gear 7.
In the work of needs low-speed and large-torque, rotary screw rod axle 10 drives shift fork 9 and stirs duplex-gear 7, and duplex-gear 7 and high speed center tooth are thrown off, and meshes with the low speed center tooth.In the time of the little moment high speed operation of needs, rotary screw rod axle 10 drives shift fork 9 and stirs duplex-gear 7, and duplex-gear 7 and low speed center tooth are thrown off, and meshes with the high speed center tooth.
