A kind of electroplating traveling crane traveling gear
Technical field
The present invention relates to a kind of electroplating traveling crane, particularly relate to a kind of electroplating traveling crane traveling gear.
Background technology
As everyone knows, driving mechanism is mainly used in hanger to be placed in different plating baths according to manufacturing technique requirent, and taking-up is transported in the plating bath of next station in predetermined time, and the quality of its design directly determines electroplating efficiency and the electroplating quality of plating line.Traveling gear is the important component part of electroplating traveling crane, and it is for driving electroplating traveling crane to advance or retreating.
At present, the following shortcoming of traveling gear ubiquity of traditional electroplating traveling crane:
1) because of Structure Designing Problem, the force-bearing situation of the parts causing bearing load larger is unreasonable, affects its service life;
2), in walking, be that simple being rolled by roller controls walking precision, make the walking precision of driving poor;
3) drive motor is fixed by welding on deep beam, and need the framework changing whole traveling gear after failsafety, installation and maintenance cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of electroplating traveling crane traveling gear, it has long service life, walking precision is high and be convenient to the feature of installation and maintenance, to solve the problems referred to above that in prior art, electroplating traveling crane traveling gear exists.
For reaching this object, the present invention by the following technical solutions:
A kind of electroplating traveling crane traveling gear, it comprises traveling vehicle frame, deep beam is provided with between described traveling vehicle frame, wherein, and the bottom of described traveling vehicle frame is provided with four rolling, described four rolling has two for driving rolls, two other is return idler, described driving rolls is installed on live axle, described live axle is connected with axle drive shaft by coupler, described axle drive shaft is connected in the drive motor on described deep beam, and described live axle is provided with gear in the outside of described driving rolls, coordinate described gear, on described traveling vehicle frame, tooth bar is installed, described return idler is installed on described follower shaft, described follower shaft is connected with transmission shaft by coupler.
Especially, the both sides correspondence of described traveling vehicle frame is provided with walking case, and described driving rolls, live axle, gear, return idler and follower shaft are all arranged in walking case, and described live axle and follower shaft are arranged on described walking case by bearing.
Especially, described drive motor is arranged on motor fixing plate, and described motor fixing plate is bolted on described deep beam.
Especially, the two ends of described driving vehicle frame are all provided with anticollison block.
Especially, the two ends of described axle drive shaft and transmission shaft are all installed on described driving vehicle frame by rolling bearing units.
Beneficial effect of the present invention is, compared with prior art described electroplating traveling crane traveling gear has the following advantages:
1) walking manner adopts rack and pinion drive mechanism and roller rolling dual-driving-mode to promote, and promote driving motion while the weight of the whole driving of roller supporting, rack and pinion drive mechanism bears driving weight hardly, only provides the thrust of driving motion.This mode improves the force-bearing situation of roller and rack-and-gear, and what extend the larger parts of these bearing loads benefits from the life-span;
2) rack and pinion drive mechanism can by controlling the location that the rotation of electrical motor realize driving a vehicle accurately, makes the walking of driving a vehicle more accurate, overcome simple roller roll control in the not high defect of roller walking precision;
3) reductor adapter plate is fixed with bolts on walking deep beam, instead of be welded on walking deep beam, make can change easily during these damage of components, and the framework of whole traveling gear need not be changed, add the interchangeability of driving parts, save installation and maintenance cost.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of electroplating traveling crane traveling gear comprises traveling vehicle frame 1, deep beam 2 is provided with between described traveling vehicle frame 1, and the bottom of described traveling vehicle frame 1 is provided with four rolling, described four rolling has two for driving rolls 3, two other is return idler 4, the both sides correspondence of described traveling vehicle frame 1 is provided with walking case 5, described driving rolls 3 is installed on live axle 6, described live axle 6 is arranged in described walking case 5 by bearing, described live axle 6 is connected with axle drive shaft 8 by coupler 7, described axle drive shaft 8 is connected in the drive motor 9 on described deep beam 2, described drive motor 9 connects reductor, described reductor is arranged on motor fixing plate 10, described motor fixing plate 10 is bolted on described deep beam 2.And described live axle 6 is provided with gear 11 in the outside of described driving rolls 3, coordinate described gear 11, on described traveling vehicle frame 1, tooth bar 12 is installed, described return idler 4 is installed on described follower shaft 13, described follower shaft 13 is connected with transmission shaft 14 by coupler 7, and described follower shaft 13 is arranged in described walking case 5 by bearing.
The two ends of described driving vehicle frame 1 are all provided with anticollison block 15, and the two ends of described axle drive shaft 8 and transmission shaft 14 are all installed on described driving vehicle frame 1 by rolling bearing units 16.
Above-mentioned driving traveling gear adopts typical four-wheel to support, the arrangement of two-wheel drive, mainly comprises two cover driving systems, is power system and servo system respectively.In power system, electrical motor provides power, be assemblied on driving rolls 3 on axle drive shaft 8 and gear 11 by coupler by rotating to be delivered to, roller rolling produces friction force and promotes the motion of whole driving mechanism, meanwhile, rack and pinion drive mechanism engages each other, and produces the thrust of driving motion, meanwhile, rack pinion can realize locating more accurately.Servo system under the promotion of power system, along guide rail movement.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
