Abstract
The utility model discloses a lightened large-size gear transmission device, comprising a box body. A group of supporting holes (1) are formed in the box body; an end cover (2) is arranged inside each supporting hole; positioning lug bosses (3) are arranged on the outer circle of the end covers; a positioning face (4) of each positioning lug boss is adhered to an inner cavity end face (5) of the box body; bearings (7) are arranged in inner holes (6) of the end covers; and the bearings are connected with a transmission gear (8) through transmission shafts. The bearing end covers provided by the utility model use a non-traditional internal structure; the positioning face of the positioning lug boss is adhered to the inner cavity end face of the box body instead of the traditional structure that the bearing end covers are mounted on the outer end faces of the box body; and the bearings are mounted in the inner holes of the bearing end covers. The gear transmission device has the advantages of simplified and compact structure, reduced volume and weight reduction; the market requirement of lightening the large-size gear transmission device can be met; the production and manufacturing cost of the product can be reduced; and the market competitive capacity of the product can be improved.

Technical field
The utility model relates to a kind of lightweight large gear transmission device, belongs to large gear transmission device technical field.
Background technique
Gear drive is important base parts and components, is widely used in the various machinery.Particularly in various types of engineering mechanical devices, gear drive is its indispensable important core component especially.Recently, along with foreign vendor enters the Domestic market one after another, market competition is growing more intense.China's construction machinery industry has obtained fast development, and various types of engineering mechanical devices are one after another towards maximizing even the future development of large.Meanwhile, as the core component of engineering mechanical device, gear drive is also towards maximizing even the future development of large.Require to maximize in addition the large development in, gear drive has been proposed light-weighted designing requirement, namely require gear drive in the situation that guarantees enough bearing capacitys, realize the purpose of reduced volume, weight reduction.
At present, the large gear transmission device that gear drive manufacturer produces still adopts traditional structural design, and its major defect is: small product size is large, Heavy Weight, manufacturing cost is high, does not satisfy the light-weighted market demand of large gear transmission device, and competitive power of product is lower.
Summary of the invention
The purpose of this utility model is, a kind of lightweight large gear transmission device is provided.Gear drive towards maximize in addition the large future development in alleviate as much as possible weight and the reduced volume of gear drive, reduce production costs, improve the market competitiveness.
The technical solution of the utility model:
A kind of lightweight large gear transmission device comprises casing; Casing is provided with one group of supported hole; Be provided with end cap in the supported hole, the end cap cylindrical is provided with positioning boss, and the interior resonator end surface of the locating face of positioning boss and casing is fitted; Be provided with bearing in the endoporus of end cap, bearing is connected with driving gear through transmission shaft.
In the aforementioned lightweight large gear transmission device, described casing comprises upper box and lower box, and the flange edge bolt that upper box is connected with lower box on the casing connects.
In the aforementioned lightweight large gear transmission device, the supported hole on the described casing is by two circular holes that semicircle orifice is combined on upper box and the lower box.
In the aforementioned lightweight large gear transmission device, described transmission shaft comprises input shaft and output shaft, and the driving gear direct-drive that input shaft is connected with output shaft connects; Or the input shaft upper transfer gear is connected with driving gear indirect drive on the output shaft through the driving gear on the above transition axis.
Compared with prior art, bearing (ball) cover of the present utility model all adopts unconventional embedding structure, the interior resonator end surface of the locating face of positioning boss and casing is fitted, rather than conventional construction is installed in the casing exterior edge face with bearing (ball) cover, and bearing is installed in the endoporus of bearing (ball) cover.Make designs simplification compactness, volume-diminished, the weight saving of gear drive, satisfy the light-weighted market demand of large gear transmission device, reduce simultaneously the manufacturing cost of product, improve the market competitiveness of product.
