Abstract
The utility model discloses a transmission device of a steel bar bending machine. A small belt pulley on a motor output shaft drives a large belt pulley; a gear coaxial with the large belt pulley is in sequential mesh transmission till driving a gear on a small bevel pinion shaft; a small bevel gear is in mesh transmission with a large bevel gear to realize the turning of the transfer force; a helical cylindrical gear on a large bevel gear shaft is meshed with a helical cylindrical gear on a main shaft, so as to further drive a working disc on the main shaft to rotate to realize the bending process of the steel bar. The utility model adopts the large and small bevel gears to realize the 90-degree turning of the transfer force, the transmission efficiency is improved, the mechanical transmission efficiency of the bevel gear can reach up to more than 95% and is higher than that of the worm transmission, therefore, the power consumption is low, the energy is saved, and the configured motor capacity can be reduced accordingly.
Description
Technical field:
The utility model relates to a kind of transmission device of Reinforcing Steel Crooking Machine, belongs to the building machinery technical field.
Background technique:
The transmission device of existing Reinforcing Steel Crooking Machine on the market, in conjunction with Fig. 1,1A, big belt pulley 3 on small belt pulley 2 drive chassis that are connected on the output shaft by motor 1 rotates, the wheel shaft the other end of big belt pulley 3 is fixed with A gear 4, A gear 4 engagement driving B gears 5, the C gear 6 engagement driving D gears 7 coaxial with B gear 5, D gear 7 is a wheel shaft with worm screw 8, worm screw 8 drives worm gear 9 and rotates, worm gear 9 is a wheel shaft with main shaft 10, the end of main shaft is fixed with working disk 11, like this, this transmission device carries out bending with the rotation that the rotation of motor output shaft is passed to working disk to reinforcing bar, and it adopts worm and gear to realize that 90 degree of transmission power turn to, but the worm and gear transmission has following shortcoming:
1., the transmission efficiency of worm and gear is low, the worm drive that Reinforcing Steel Crooking Machine adopts is self-locking, its transmission efficiency lower (40%～45%), so power consumption is big, not energy-conservation, the drive motor capacity of configuration also needs corresponding increasing.
2., since work characteristic, the worm drive fretting wear is bigger, wherein the wearing and tearing of worm gear are to influence the product weak link in working life.
3., worm drive heating is big, should not adopt grease lubrication.Owing to traffic requirements, lubricant oil inconvenience is filled up when dispatching from the factory, and preceding necessary oiling of use can not be too much or very few, lubricates to be not so good as grease lubrication conveniently.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of transmission device of Reinforcing Steel Crooking Machine, can realize high transmission efficiency, and can reduce power consumption.
The utility model technical solution problem adopts following technological scheme:
The transmission device of Reinforcing Steel Crooking Machine, comprise the motor that is fixed with small belt pulley on the output shaft that is fixedly arranged on the frame, described small belt pulley drives big belt pulley, the other end at described big belt pulley wheel shaft is fixed with the A gear, described A gear and B meshed transmission gear, C gear and the D meshed transmission gear coaxial with the B gear, the wheel shaft the other end of described D gear is installed with small conical gear, large conical gear with described small conical gear engagement is set on frame, be installed with the A helical gear on the wheel shaft of described large conical gear, the B helical gear that mesh with described A helical gear are rotating shaft with the main shaft, and working disk is fixedly arranged on the end of described main shaft;
The wheel shaft of described A gear, B gear and D gear is parallel to each other and is set up in rotationally on the described frame, the wheel shaft of described large conical gear and described spindle parallel and be set up in rotationally on the described frame, and described main shaft is vertical with the wheel shaft of described D gear.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1., the utility model carries out bending with the rotation that the rotation of motor output shaft is passed to working disk to reinforcing bar, it adopts large and small cone gear to realize that 90 degree of transmission power turn to, improve transmission efficiency, the machinery driving efficiency of Bevel Gear Drive can reach more than 95%, is much higher than worm geared machinery driving efficiency.Therefore power consumption reduces, and energy-conservation, the capacity motor of configuration also can correspondingly reduce.
2., increase the service life, the wearing and tearing of cambered surface Bevel Gear Drive are much smaller than worm drive, the working life of product lengthening.
3., lubricated convenient, the used hyperboloid Bevel Gear Drive of this Reinforcing Steel Crooking Machine adopts grease lubrication, can use for a long time needn't be often grease-added, lubricated convenient.
4., replace worm drive, make the entire product total volume reduce to some extent with Bevel Gear Drive.
