Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
As shown in fig. 1 to 2, the utility model discloses circulating metal casting for equipment gear wheel of structure includes ring gear 100, ring gear frame 200, the ring gear includes annular ring gear body 101 and sets up the teeth of a cogwheel 104 on the circumference outside the ring gear body, a side end face at the ring gear is provided with a plurality of connecting holes 102 and supplies to be connected with the ring gear frame, ring gear frame 200 includes the ring gear frame body 201 of disc, with the coaxial gear hole 205 that is provided with of ring gear frame body, be provided with a plurality of connect the via hole 202 on the terminal surface of ring gear frame, connect the via hole 202 and the size and the position homogeneous phase of connecting hole 102 on the ring gear match, be used for being connected with the ring gear, ring gear and the coaxial setting of ring gear frame are through screw or bolt fixed connection and are integrative. Preferably, two end faces of the gear ring frame are both inwards concave to form grooves 203, the thickness of the outer circumference of the joint of the gear ring frame and the gear hole at the shaft joint is larger than that of other parts of the gear ring frame, and the supporting capacity of the gear ring frame for the gear ring is improved under the condition that the weight and materials of the whole gear ring frame are not obviously increased. Preferably, lightening holes 204 are formed in the end face of the ring gear carrier to further reduce the weight thereof. The gear wheel with the structure is adopted, because the gear teeth are arranged on the gear ring, the gear ring can be independently replaced when the gear teeth are abraded without replacing the whole gear wheel, the running cost of equipment is reduced, and a more convenient condition is that when the gear is manufactured, the gear teeth part directly participating in driving, namely the gear ring can be manufactured by high-quality materials, the gear ring frame can be manufactured by common materials, for example, the gear ring can be made by high-quality alloy steel 42CrMo, the gear ring frame is manufactured by 45 steel casting, the wear resistance and the like of the whole gear wheel can be greatly improved, the cost is correspondingly not increased, and the cost of the whole wearing part is reduced. In a more preferable embodiment, the gear ring is a gear block 103 in a block mode, the gear ring is composed of a plurality of sections of arc plates with teeth on the outer circumference, namely the gear block, the outer diameter and the inner diameter of each arc plate are equal, and the arc plates are butted to form a circular ring. The radian of each arc plate can be equal or unequal, and the structure that the radians of partial gear blocks are equal and the parts are unequal is generally adopted, so that the gear structure can be more suitable. The advantage of adopting sectional type ring gear lies in can changing the gear piecemeal alone when local teeth of a cogwheel wearing and tearing are serious, need not change whole ring gear, more need not change whole gear, reduces later stage maintenance cost.
In a more preferred structure, the outer diameter of the gear ring frame is smaller than the diameter of the tooth root circle of the gear ring.
The embodiment is as follows:
