Abstract
The utility model relates to the field of tractor transmission case, which is a creep drive internal gear ring apparatus. The initially processed gear ring is connected to the gear ring seat as a whole, welding is performed on the welding position, the gear ring is a forging stock, and the gear ring seat is cast steel billet. As the technical scheme is adopted, the casting technique performance of the gear ring seat body is improved, the phenomenon of casting shrinkage is cast gear ring seat is eliminated, the casting yield is improved, the fabricating cost is reduced, and simultaneously the gear ring intensity is improved as the gear ring adopts steel forging piece.
Description
Technical field
The utility model relates to the tractor transmission case field, is a kind of transmission ring gear device of creeping.
Background technique
The transmission ring gear of creeping is the vital part of transmission of creeping in the big-powered tractor transmission case, its complex structure, adopt integral cast steel spare, remake machining, because of the design of part complexity, entity and shape difference in thickness are bigger, cause the blank castability poor, ring gear position in key easily exists shrinkage porosite and pore, is difficult to eliminate and control, has influenced the usability and the life-span of product.And the cast steel blank up-to-standard rate is low, and cost of goods manufactured is high.
Summary of the invention
The purpose of this utility model is that a kind of new structure will be provided, and can solve the quality problems of ring gear.
The utility model is achieved in that the gear ring of preparatory processing and gear ring base is connected as one that weld, gear ring is a forging stock spare on welding position, gear ring base is a cast steel blank.
Owing to adopted technique scheme, gear ring base body casting technique performance improves, and foundry goods shrinkage porosite phenomenon is eliminated, and casting qualified rate improves, and has reduced manufacture cost, and gear ring adopts steel satin spare simultaneously, has improved gear ring intensity.
Description of drawings
Fig. 1 is an internal structure schematic representation of the present utility model.
In the drawings: 1, gear ring; 2, gear ring base; 3, welding position.
Embodiment
The utility model is further described below in conjunction with drawings and Examples.
In Fig. 1, the gear ring 1 and the gear ring base 2 of preparatory processing connected as one, on welding position 3, weld, gear ring 1 is a forging stock spare, gear ring base 2 is a cast steel blank.Again the transmission ring gear of creeping that is welded as a whole is carried out internal gear processing.
