Abstract
The utility model discloses a crowned tooth coupler of separated internal gear rings, which structurally and mainly comprises an outer gear shaft sleeve, inner gear rings and end covers; the inner gear rings with the end covers on both ends are sleeved on the outer side of the outer gear shaft sleeve; and the inner gear rings are separated. The separated inner gear rings are two inner gear rings which are axially sub-divided and are connected and combined together through a bolt, a washer and a nut. The middle positions of the separated inner gear rings are provided with positioning rings for positioning. The crowned tooth coupler adopts some inner gear rings and positioning rings to position. The adopted inner gear rings which are axially sub-divided are very convenient for a user to install, detach, decompose and view the tooth wear of the inner gear rings. Simultaneously, because the positioning rings are adopted to position, the ordered spare parts of the inner gear rings can be reduced by 50 percent so as to greatly reduce the replacement and maintenance time and the spare part cost and bring great economic benefits for the user.
Description
Technical field
The utility model relates to crown gear coupling, specifically a kind of crown gear coupling of split type inner gear ring.
Background technique
Gear coupling is divided into straight-tooth coupling and crown gear coupling, straight-tooth coupling NBS the earliest is to formulate in China's sixties, the structure of its citation form is two ring gears and two external tooth axle sleeve engagements, two inner, outer stopper location of ring gear, link together with the articulation hole screw bolt and nut, by the engagement and the articulation hole bolt transmitting torque of tooth.Because its angle compensation rate allowable has only 1 degree, volume was also bigger, and China made the standard of crown gear coupling in 1986.The standard No. of citation form is JB/ZQ4378-86, and the structure of citation form is identical with straight-tooth, and just the tooth of external tooth axle sleeve adopts crowned teeth, and its angle compensation rate allowable rises to 1.5 degree, has adopted better material simultaneously, has reduced the volume of coupling.Because being the engagement of inner tooth and external tooth, crown gear coupling comes transmitting torque, the engagement of internal tooth and external tooth is equivalent to spline and is connected, therefore, the coupling of crown gear coupling and other types is compared, under the identical situation of volume, the torque transmitted maximum is so be widely used in steel mill, colliery, power plant, harbour etc.For example: milling train, roller-way, driving, belt conveyor etc.
Crown gear coupling, as shown in Figure 1, structure comprises external tooth axle sleeve, inner stopper ring gear, positioning spigot, outer stopper ring gear substantially, crown gear coupling finds to have three big shortcomings in actual use:
1. ring gear and external tooth axle sleeve engagement in use, it is thiner that ring gear is compared the external tooth axle sleeve, and the odontotripsis of ring gear is faster.Because ring gear is a whole circle, want to see the abrasion condition of the tooth of ring gear when safeguarding, two kinds of methods are often arranged, the one, the slit between ring gear and external tooth axle sleeve roughly look at that it is inaccurate that this method is seen; The 2nd, need pull down ring gear in the time of carefully seeing and see, this method see accurately but must take apart and remove link (as speed reducer) and just can pull down ring gear, need a lot of workloads and man-hour, and regard one's time as if it were gold all in the place of above-mentioned use.
2. when ring gear wearing and tearing need to change, must take apart and remove link (as speed reducer) and just can take off ring gear, need a lot of workloads and man-hour equally.In addition, two inner, outer stopper location of ring gear, two ring gear differences, promptly inner stopper ring gear and outer stopper ring gear do not damage earlier because of knowing which part ring gear, will order two ring gears when therefore ordering spare part.
3. on the equipment that drive (as belt conveyor) more, when also will moving, the driving equipment that breaks down (on the equipment that drive standby driving is arranged all generally) more, must disconnect this drive unit that breaks down, link (as speed reducer) has no time to remove this moment, can not pull down ring gear, ring gear can only be followed idle running on the external tooth axle sleeve, treat just can pull down if having time, and is so very dangerous.
The model utility content
(1) technical problem that will solve
The purpose of this utility model is the defective that exists at prior art, and a kind of crown gear coupling of split type inner gear ring is provided, solved that prior art exists, be not easy to remove and defective and problems such as maintenance.
(2) technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: a kind of crown gear coupling of split type inner gear ring, and its structure mainly comprises external tooth axle sleeve, ring gear, end cap; The ring gear that described two ends are provided with end cap is placed in the external tooth axle sleeve outside; Described ring gear is split type ring gear.
Described split type ring gear is the ring gear of two axial subdivisions, connects by bolt, packing ring, nut and combines.
The placement positioning ring positions in the middle of the described split type ring gear.
(3) beneficial effect
The crown gear coupling of a kind of split type inner gear ring of the present utility model is compared with prior art, has following beneficial effect:
The utility model has adopted subdivision ring gear and positioning ring location.Owing to adopted the axial subdivision ring gear, be convenient to very much the abrasion condition that installing/dismounting decomposes, watches the tooth of ring gear.Owing to adopted the positioning ring location, the size of order of ring gear spare part can reduce half, thereby has significantly reduced replacing maintenance time and spare part cost, can be the user and brings great economic benefit simultaneously.
