Abstract
A new type of self aligning small gear device for rotary kilns mainly comprises a gear shaft (2), a small gear (4), a semispherical surface ring (5) and a semispherical surface base (7), the two ends of the gear shaft are fixed on a shaft base (1) through a bearing, the gear shaft is provided with an arc outer tooth (6), which is provided with the semispherical surface base on its two sides, the arc outer tooth is meshed with an inner tooth on the internal diameter of the small gear, the inner tooth on the internal diameter of the small gear is provided with the semispherical surface ring on its two sides, the small gear is fixed on the gear shaft through supporting of the two semispherical surface ring on the two sides of the inner tooth on the internal diameter thereof and the two semispherical surface base on the gear shaft, a sleeve (3) is fixed on the outside of the small gear by a screw (8). The utility model is simple structured and is convenient to fix and maintain, with low producing cost and strong self aligning function so as to prevent the damage of the gear tooth caused by the deflecting load and expand service life of the gear.
Description
Technical field:
The utility model relates to the design and manufacturing technology field of the rotary kiln device in the industrial field, particularly a kind of new type auto positioning pinion device that is used for rotary kiln.
Background technique:
Rotary kiln is that in bulk or pasty material are processed heat treated Thermal Equipment, is widely used in cement, nonferrous metallurgy, iron and steel industry, chemical industry, industrial fields such as papermaking.
The open type type of belt drive of rotary kiln has two kinds at present: the one, and small gear is a rigid construction, and there is roller bearings at two ends, and the speed of this structure transmission and power range are very big, and the transmission efficiency height is simple in structure, assembles and keep in repair fairly simple.Shortcoming is that in use small gear can not change with gearwheel, unbalance loading occurs easily and causes the damage of the flank of tooth, and impact shock is big, and the life-span of gear pair is reduced.The 2nd, pinion device is flexible transmission, it is the transmission that the form of pinion device and worm type of reduction gearing employing half suspension that matches with it or integral is driven gearwheel, small gear can be floated with gearwheel, guarantee that gear all can correctly mesh under texturizing condition.Its compact structure, in light weight.Impact shock is little, and running steadily.Shortcoming is the driving mechanism complexity, the equipment manufacturing cost height, and the field maintenance amount is big.
Summary of the invention:
For overcoming above-mentioned problems of the prior art; the purpose of this utility model provides a kind of new type auto positioning pinion device that is used for rotary kiln; it processes internal tooth by the stage casing at the small gear internal diameter; tooth top embeds in the internal tooth teeth groove of pinion gear aperture for the arc external tooth on gear shaft; thereby make small gear have the function of automatic positioning, effectively protected equipment.
For achieving the above object, the utility model adopts following technological scheme:
Described a kind of new type auto positioning pinion device that is used for rotary kiln, it is mainly by gear shaft, small gear, hemisphere face ring and hemisphere face seat constitute, the gear shaft two ends by Bearing Installation on bearing support, gear shaft is provided with the arc external tooth, the both sides of arc external tooth are provided with the hemisphere face seat are installed, the arc external tooth is meshed with internal tooth on the small gear internal diameter, internal tooth both sides on the internal diameter of small gear are provided with the hemisphere face ring are installed, small gear is installed on the gear shaft by two hemisphere face rings of the internal tooth both sides on its internal diameter and two hemisphere face seat supports on the gear shaft, and the outside of small gear is equipped with sleeve by screw.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
Described a kind of new type auto positioning pinion device that is used for rotary kiln, it is simple in structure, convenient for installation and maintenance, cost is low, strong from bit function, when the engagement of itself and gear ring, even the kiln body is in manufacturing, install and adverse condition such as kiln body bending that factor such as thermal distortion causes, all can keep nearly 100% the flank of tooth to contact mottling by the good automatic positioning performance of small gear and the flank of tooth.Thereby the flank of tooth of avoiding unbalance loading and causing damages, and prolongs the working life of gear.
Description of drawings:
Fig. 1 is the structural representation of the new type auto positioning pinion device of this rotary kiln;
Among the figure: the 1-bearing support; The 2-gear shaft; The 3-sleeve; The 4-small gear; 5-hemisphere face ring; 6-arc external tooth; 7-hemisphere face seat; The 8-screw.
Specific embodiment:
As shown in fig. 1: the new type auto positioning pinion device of this rotary kiln, it is mainly by gear shaft (2), small gear (4), hemisphere face ring (5) and hemisphere face seat (7) constitute, gear shaft (2) two ends by Bearing Installation on bearing support (1), gear shaft (2) is provided with arc external tooth (6), the both sides of arc external tooth (6) are provided with hemisphere face seat (7) are installed, arc external tooth (6) is meshed with internal tooth on small gear (4) internal diameter, internal tooth both sides on the internal diameter of small gear (4) are provided with hemisphere face ring (5) are installed, small gear (4) is installed on the gear shaft (2) by two the hemisphere face rings (5) and the support of two the hemisphere face seats (7) on the gear shaft (2) of the internal tooth both sides on its internal diameter, and the outside of small gear (4) is installed with sleeve (3) by screw (8).
During work, tooth top on gear shaft (2) is that arc external tooth (6) embeds in the internal tooth teeth groove on small gear (4) internal diameter, through chimeric interior external tooth torque is delivered on the small gear (4) from gear shaft (2), thereby drive the gear ring running be loaded on the kiln cylinder body, small gear (4) is to be implemented in supporting on the gear shaft (2) and positioning by two the hemisphere face rings (5) that are arranged in the internal tooth both sides and two the hemisphere face seats (7) on the gear shaft (2).These two hemisphere face rings (5) are realized axial restraint by screw (8) and two sleeves (3) of small gear body end face.
Claims (1)
1, a kind of new type auto positioning pinion device that is used for rotary kiln, it is characterized in that: it is mainly by gear shaft (2), small gear (4), hemisphere face ring (5) and hemisphere face seat (7) constitute, gear shaft (2) two ends by Bearing Installation on bearing support (1), gear shaft (2) is provided with arc external tooth (6), the both sides of arc external tooth (6) are provided with hemisphere face seat (7) are installed, arc external tooth (6) is meshed with internal tooth on small gear (4) internal diameter, internal tooth both sides on the internal diameter of small gear (4) are provided with hemisphere face ring (5) are installed, small gear (4) is installed on the gear shaft (2) by two the hemisphere face rings (5) and the support of two the hemisphere face seats (7) on the gear shaft (2) of the internal tooth both sides on its internal diameter, and the outside of small gear (4) is installed with sleeve (3) by screw (8).
