Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gears, and particularly relates to a small gear with a cover structure. Background Art
[0002] During the transmission of a small gear, lubricating grease needs to be applied to the gear to reduce wear during transmission. However, due to the complex processing environment, foreign dust in the external air will fall onto the gear, resulting in contamination of the lubricating grease on the gear and affecting the service life of the gear.
[0003] The existing small gears used in transmission lack a protective structure, which is prone to causing the risk of accidental entanglement of external objects or personnel's limbs, affecting the safety of use.
[0004] Based on the existing drawbacks of small gears: the existing small gears used in transmission have no protective structure, which is prone to causing contact between external objects and the sprocket of the gear, affecting the service life of the lubricating oil, and at the same time, the operation of personnel around the gear is highly dangerous. For this reason, we propose a small gear with a cover structure. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a small gear with a cover structure, which can effectively solve the problems in the background art.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A small gear with a cover structure includes a gear, an arched protective cover and a damping hinge, and also includes a transmission shaft rod, a transmission shaft rod slot and an installation ear. The arched protective cover covers the gear. One end of the bottom of the arched protective cover is provided with a damping hinge. The hinge at one end of the damping hinge is welded to one end of the bottom of the arched protective cover. The other end of the bottom of the arched protective cover is welded with an installation ear.
[0008] Further, a transmission shaft rod is installed in the center of the gear through a key pin.
[0009] Further, transmission shaft rod slots corresponding to the transmission shaft rod are respectively opened at both ends of the arched protective cover.
[0010] Further, installation holes are respectively opened on the hinge at the other end of the damping hinge and the installation ear.
[0011] Compared with the prior art, the utility model has the following beneficial effects: The assembly composed of a gear, an arched protective cover, a damping hinge, a transmission shaft rod, a transmission shaft rod notch and a mounting ear realizes providing a protective structure for the pinion assembly for assisting the processing environment, and the pinion structure with the protective structure can effectively reduce the contact of external foreign objects and dust with the gear tooth disc, so as to avoid the service life of the lubricating oil when the gear is smeared with lubricating oil and reduce the problem of the lubricating oil being polluted by external dust and foreign objects. At the same time, through the addition of the protective structure, the safety of the gear working time can be improved, and accidental contact and entanglement of surrounding articles or personnel can be avoided. At the same time, the arched protective cover for protection can be opened and closed flexibly. The pinion with the protective cover structure of the present application has good use stability, and solves the problems that the existing pinion for transmission has no protective structure, is easy to cause the contact of external articles with the tooth disc of the gear, affects the service life cycle of the lubricating oil, and at the same time, the operation risk of the personnel around the gear is high.

[0017] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.
[0018] Such as Figures 1-4As shown in the figure, a pinion gear with a protective cover structure includes a gear 1, an arched protective cover 3, and a damping hinge 5. It also includes a transmission shaft rod 2, a transmission shaft rod notch 4, and a mounting ear 6. The gear 1 is covered with an arched protective cover 3. One end of the bottom of the arched protective cover 3 is provided with a damping hinge 5. The hinge at one end of the damping hinge 5 is welded to one end of the bottom of the arched protective cover 3. The other end of the bottom of the arched protective cover 3 is welded with a mounting ear 6. The transmission shaft rod 2 is installed in the center of the gear 1 through a key pin. Transmission shaft rod notches 4 corresponding to the transmission shaft rod 2 are respectively opened at both ends of the arched protective cover 3. Mounting holes 7 are opened on the hinge at the other end of the damping hinge 5 and on the mounting ear 6.
[0019] It should be noted that the present utility model is a pinion gear with a protective cover structure.
[0020] During operation, the operator covers the top of the gear 1 with the arched protective cover 3 and ensures that the arched protective cover 3 does not contact the gear 1 and the transmission shaft rod 2, so that the gear 1 can perform normal transmission work. Subsequently, the mounting holes 7 on the damping hinge 5 and the mounting ear 6 are installed on the frame, ground, etc. of the working environment of the gear 1 through bolts, so that the periphery of the gear 1 is protected. It can prevent external objects from directly contacting the gear 1 and improve the stability of gear use. When it is necessary to repair and maintain the gear 1, the operator removes the screws on the mounting ear 6, and then can turn over and open the arched protective cover 3 from the mounting ear 6 end of the arched protective cover 3, so that the gear 1 can be exposed, enabling the operator to contact and maintain the gear 1.
