Abstract
The utility model discloses a welded eccentric gear structure, which comprises a hub, a gear ring, an eccentric ring and a balancing weight which are welded; webs are welded on two sides of the hub respectively, a middle cavity is formed between the two webs, and a plurality of steel pipes are arranged between the two webs in a penetrating mode and connected through welding; the eccentric ring is arranged at the position of the hub close to the lower end; the balancing weight is arranged in the middle cavity and is close to the upper end of the hub. In the utility model, compared with the existing casting process, the eccentric gear with a welded structure is adopted, so that a complex gear structure can be avoided, more holes designed during casting are eliminated, and the comprehensive performance of the eccentric gear is improved; the structure is more simple and reasonable, the production, assembly and processing are relatively convenient and fast to carry out relative casting processes, the yield is higher, and the practicability and the economy are higher.
Description
Technical Field
The utility model relates to an eccentric gear makes technical field, concretely relates to welding formula eccentric gear structure.
Background
In the prior art, eccentric gears are usually produced by a casting process, as shown in fig. 1-2, the structure of a cast gear is complex, and in consideration of the casting process and cost, the eccentric gears have many holes, which greatly affects the comprehensive performance of the eccentric gears, has low yield, and has high production cost for non-mass-produced eccentric gears.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art, and provides a welded eccentric gear structure which comprises a hub, a gear ring, an eccentric ring and a balancing weight, wherein the hub, the gear ring, the eccentric ring and the balancing weight are welded; webs are welded on two sides of the hub respectively, a middle cavity is formed between the two webs, and a plurality of steel pipes are arranged between the two webs in a penetrating mode and connected through welding; the eccentric ring is arranged at the position of the hub close to the lower end; the balancing weight is arranged in the middle cavity and is close to the upper end of the hub.
In order to improve the integral structural strength of the eccentric gear, a plurality of vertical supporting plates are welded between the eccentric ring and the bearing mounting hole of the hub.
Furthermore, the vertical supporting plate is in a slope shape.
Furthermore, a horizontal supporting plate is welded between the eccentric ring and the bearing mounting hole of the hub.
In order to facilitate the discharge of gas left during welding, furthermore, the horizontal supporting plate is provided with a plurality of exhaust holes.
In order to furthest ensure that the problem of web collapse cannot be caused when the eccentric gear runs, furthermore, the six steel pipes are circumferentially distributed on the outer side of the eccentric ring.
Has the advantages that: in the utility model, (1) the eccentric gear with a welded structure is adopted, so that compared with the existing casting process, the complex gear structure can be avoided, more holes designed during casting are eliminated, and the comprehensive performance of the eccentric gear is improved;
(2) the structure is simpler and more reasonable, the production, assembly and processing are more convenient and faster compared with the casting process, the yield is higher, and the practicability and the economy are higher;
(3) the steel pipe welded between the two layers of webs can provide support for the webs, the problem of web collapse during operation is avoided, process clamping is facilitated, the sealing performance of the interior of the webs can be guaranteed through the welded steel pipe, and cutting fluid during processing and lubricating oil during operation cannot be poured into the middle cavity to affect the performance of the eccentric gear;
(4) the balancing weight close to the upper end of the hub enables the center of gravity of the eccentric gear to be centered as much as possible, so that the clamping during machining is facilitated, and the safety of machining equipment and operators is protected to a certain extent.
