Description

Silicone oil shock absorber for generating cyclone

Technical Field

The invention relates to the technical field of automobile manufacturing, in particular to a rotary silicone oil damper.

Background

The torsional vibration damper used in the present automobile engine includes two categories, namely a silicone oil damper and a rubber damper.

The traditional silicone oil damper consists of seven parts, namely a shell, a core plate, an inertia ring, silicone oil, a cover plate, a bearing, a plug and the like, wherein the shell, the core plate and the cover plate are connected together in an electron beam welding mode, the inertia ring is arranged inside the shell and the cover plate, and the periphery of the inertia ring is filled with the silicone oil. In use, the housing is connected to a crankshaft. When the engine rotates, the shell, the crankshaft and the inertia ring suspended in the inner cavity of the shell rotate simultaneously. When the shafting vibrates, the vibration energy is absorbed through inertia of the inertia ring and damping of the silicon oil, and the vibration damping effect is achieved.

Because the silicon oil shock absorber has too many assembled parts, each part has a tolerance, and the potential risk that the shock absorber can fail due to the fact that the parts are assembled together on the upper line of the tolerance or on the lower line of the tolerance is inevitable in the assembling process; the core plate needs to be welded with the shell and the cover plate together by an electron beam welding machine, the process is complex, the efficiency is low, and the welding deformation risk is easy to occur.

Disclosure of Invention

The invention aims to provide a silicone oil damper which is optimized to be that a shell and a core plate are directly rotated into a whole by adopting a spinning process, welding procedures of the core plate and the shell are reduced, and the excircle runout and related dimensions are better ensured.

In order to achieve the purpose, the invention adopts the following technical scheme: a rotary silicone oil damper comprises a cover plate (9), an inertia ring 4, a shell (5), a core plate (6), two thrust plates (7) with symmetrical positions and a bearing (8);

the shell (5) and the core plate (6) are connected into a whole to form a shell, the inertia ring (4) is placed in the shell, two thrust plates (7) are placed in counter bores of the inertia ring (4), and a bearing (8) is placed at the edge of the inertia ring;

the cover plate (9) is welded at a step reserved after the shell (5) is machined, and a complete silicon oil shock absorber is formed after silicone oil is injected through the oil injection hole and blocked;

when the engine rotates, the shell, the crankshaft and the inertia ring suspended in the inner cavity of the shell rotate simultaneously. When the shaft system vibrates, the vibration energy is absorbed through inertia of the inertia ring and damping of the silicon oil, and the vibration reduction effect is achieved.

The invention has the beneficial effects that: compared with the traditional design scheme, the device changes the process of manufacturing the core plate separately and then welding. The welding fixture has the advantages that the size is convenient to guarantee, and welding procedures and assembling risks are reduced; the manufacturing and labor cost is reduced; and the potential failure coefficient of the silicone oil damper is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a damper for generating rotary silicone oil comprises a tooth socket 2, a cover plate 9, an inertia ring 4, a shell 5, a core plate 6, a bearing 8 and two thrust plates 7 which are symmetrical in position, wherein after assembly and welding are carried out, a proper amount of silicone oil is filled into an oil filling hole, and then welding is carried out to block the oil filling hole, so that a complete silicone oil damper is formed.

The shell 5 and the core plate 6 are produced and screwed out together through a rotary production machine, the shell and the core plate are processed to a specified size, the inertia ring 4 which is processed to the specified size after casting is placed, thrust plates which reach the specified size are placed on counter bores of the inertia ring 4, and a bearing 8 is placed at the edge; putting the cover plate which is subjected to punch forming and then numerically controlled lathed to a specified size, welding the cover plate by using a beam welding machine, and then injecting silicone oil; and (5) after welding and blocking, finishing. And the radiating fins can be additionally welded according to the requirements of customers.

The shell 5 and the core plate 6 are connected into a whole, and the core plate 6 can be screwed on the bottom surface, the middle part and all required parts. The tooth grooves 2 connected with the belt can be screwed out together when the shell is screwed. The size of the inner cavity is 50 mm-300 mm, and the size of the shell is 100mm-500 mm; the height of the shell 5 can be 30 mm-200 mm to realize the rotation.

The working principle is as follows: when the engine rotates, the shell, the crankshaft and the inertia ring suspended in the inner cavity of the shell rotate simultaneously. When the shafting vibrates, the vibration energy is absorbed through inertia of the inertia ring and damping of the silicon oil, and the vibration damping effect is achieved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention should be covered by the scope of the present invention.
