Abstract

The utility model relates to a buffering gear device comprising an external snap spring, an internal wheel of buffering gear, six polyurethane rods and an external wheel of buffering gear, wherein the six polyurethane rods are installed in the circular arcs of the external wheel of buffering gear, the internal wheel of buffering gear is installed in the external wheel of buffering gear, and the external snap springs are clamped in a snap spring groove on the external wheel of buffering gear for fixing the internal wheel of buffering gear with the external wheel of buffering gear. 6 circular arcs are arranged on the external wheel of buffering gear. The buffering gear device provided by the utility model is compact and reasonable in structure and is capable of avoiding damage on the gear and the whole motor structure caused by an impact force generated in the case of collision or an inertial impact force generated in the case of sudden stop of the door body of a translation door; and a part of force is buffered to protect the motor and the door body.

Description

The buffer gear cold device

Technical field

The utility model relates to a kind of gear, specifically is used for a kind of buffer gear cold device on the translation door motor output shaft, belongs to the translation door machine field.

Background technique

In prior art, the gear that adopts on translation door motor defeated place axle is general ordinary gear, and buffer function, in use do not run into collision and can not play buffer function, thereby can not protect motor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of buffer gear cold device is provided, and this gear has solved translation every body when being subject to colliding, and can play the protective action to motor and door body.

According to the technological scheme that the utility model provides, the buffer gear cold device comprises wheel in wild card jump ring, buffer gear cold, polyurethane rod, buffer gear cold foreign steamer; The polyurethane rod is placed in the circular arc of buffer gear cold foreign steamer, and wheel being arranged in the buffer gear cold foreign steamer in described buffer gear cold, and the wild card jump ring is stuck in jump-ring slot on the buffer gear cold foreign steamer, and wheel and buffer gear cold foreign steamer in buffer gear cold are fixed.

As further improvement of the utility model, described polyurethane rod adopts six.Described buffer gear cold foreign steamer is provided with six circular arcs.

Compared with the prior art the utility model has the following advantages:

The utility model compact structure, rationally, the destruction that the inertial impact force that has produced when having solved the impact force that produces when translation every body is subject to colliding or cut produces gear and whole electric machine structure; Buffering is fallen a part of power, thereby realize the protection to motor and door body.

Description of drawings

Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.

Embodiment

Following the utility model is further described in connection with the embodiment in accompanying drawing:

As shown in Figure 1, comprise wheel 2, polyurethane rod 3, buffer gear cold foreign steamer 4 etc. in wild card jump ring 1, buffer gear cold.

The utility model is provided with six circular arcs on buffer gear cold foreign steamer 4, first six polyurethane rods 3 are placed in six circular arcs of buffer gear cold foreign steamer 4, and then wheel 2 in buffer gear cold is arranged in the buffer gear cold foreign steamer 4 of putting polyurethane rod 3 well.At last wild card jump ring 1 is stuck in the jump-ring slot of reserving on buffer gear cold foreign steamer 4, is used for wheel 2 and buffer gear cold foreign steamer 4 in buffer gear cold are fixed.

Working principle of the present utility model and working procedure:

The utility model was contained in buffer gear cold on the output shaft of translation door motor in when work, then drove tooth bar on translation every body by this buffer gear cold and made door the action such as can open, stop, closing.When door was suddenly stopped or collides other object, the polyurethane rod in the utility model can cushion some impact forces, thereby can protect the effect of each structure on the translation door motor.
