Description

Gear with long service cycle

Technical Field

The utility model relates to the technical field of gears, in particular to a gear with a long service cycle.

Background

It is well known that gears are already very common today, for which wear between the teeth of a gear and the teeth of another gear is a major factor affecting the life cycle of the gear, and for which there are several ways today, such as enhanced lubrication and more wear resistant materials, but the main wear of a gear is at cold start, because at cold start the lubrication of the gear is not in place, there is no or only very little attached lubrication on the gear, and at this time there is a so-called direct wear between the gears, while waiting for lubrication of the gear by the lubrication oil, the gear has rotated several turns, thus resulting in a larger wear of the gear at cold start.

(II) technical scheme

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a long gear of life cycle, includes the tooth body and several teeth of a cogwheel to the several teeth of a cogwheel sets up on the tooth body, is provided with the oil trap on the tooth body between every two teeth of a cogwheel, one side of oil trap is darker than the opposite side, be the circular arc transition between shallow one side of oil trap and the tooth body, the left and right sides of both sides all becomes the opening form setting around the oil trap.

Further, the maximum distance between the front side and the rear side of the oil collecting groove and the front and rear distance of the tooth body is not more than 20%, and the minimum distance between the front side and the rear side of the oil collecting groove and the front and rear distance of the tooth body is not more than 10%.

Further, the shallow side of the oil collecting groove is in arc transition with the tooth body,

further, a side oil groove is formed in the deeper side of the oil collecting groove.

Further, the side oil grooves are arranged in a semi-cylindrical shape.

(III) beneficial effects

Compared with the prior art, the utility model provides a gear with long service cycle, which comprises the following components

The beneficial effects are that:

this long gear of life falls into the oil sump through the lubricating oil after the gear stop work to when cold start, let the lubricating oil in the oil sump flow to the teeth of a cogwheel, thereby play timely lubricated effect to the gear, make this gear receive the wearing and tearing littleer when cold start, and then effectually promoted the life cycle of gear.

In the figure: 1. a tooth body; 2. gear teeth; 3. an oil sump; 4. side oil groove.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the gear with a long service cycle of the present utility model includes a gear body 1 and a plurality of gear teeth 2, wherein the plurality of gear teeth 2 are arranged on the gear body 1, an oil collecting groove 3 is arranged on the gear body 1 between every two gear teeth 2, the oil collecting groove 3 can collect lubricating oil on the gear, when the gear stops rotating, the lubricating oil on the gear can slide down along with gravity, and the lubricating oil on the inclined surfaces on two sides of the gear teeth 2 can slide down along with gravity as in the oil collecting groove 3, so as to be collected by the oil collecting groove 3, when the gear is cold started, the gear rotates, so that the lubricating oil in the oil collecting groove 3 slides out of the oil collecting groove 3 along with gravity and slides into the gear teeth 2, thereby playing a role of timely lubrication.

One side of the oil collecting groove 3 is deeper than the other side, one shallow side of the oil collecting groove 3 is close to one side of the main friction surface of the gear teeth 2, one deep side of the oil collecting groove 3 is close to one side of the non-main friction surface of the gear teeth 2, and arc transition is formed between the shallow side of the oil collecting groove 3 and the gear body 1, so that lubricating oil can flow smoothly.

The left and right sides of the front and back sides of the oil sump 3 are all arranged in an opening shape, so that the area of the oil sump 3 for collecting oil can be increased, and lubricating oil can be lubricated more uniformly when flowing out of the oil sump 3.

The maximum distance between the front side and the rear side of the oil collecting groove 3 and the front and rear distance of the tooth body 1 is not more than 20% of the front and rear distance of the tooth body 1, and the minimum distance between the front side and the rear side of the oil collecting groove 3 and the front and rear distance of the tooth body 1 is not more than 10% of the front and rear distance of the tooth body 1, so that the rigidity of the influence gear can be reduced, and the size of the oil collecting groove 3 can be larger while the rigidity of the gear is less influenced.

The shallow side of the oil collecting groove 3 and the tooth body 1 are in arc transition, so that the resistance of the lubricating oil flowing can be reduced, and the lubricating oil can be guided to flow.

The deeper one side of oil sump 3 is provided with side oil groove 4, and the oil sump 3 of side oil groove 4 setting can let the gear right part also collect lubricating oil through side oil groove 4, and side oil groove 4 is the semicylindrical setting to owing to set up to be the semicylindrical, can let side oil groove 4 also can have a certain amount of lubricating oil, when the gear rotates, can have the lubrication effect the same as oil sump 3.

In this scheme, though oil collecting groove 3 only can lubricate the teeth of a cogwheel 2 at the gear top when cold start, but because factors such as tooth ratio etc. just can let all receive the lubrication of some lubricating oil on teeth of a cogwheel 2 after the gear rotates several circles, wait for the lubrication system of machine to lubricate the back with lubricating oil to the gear, the gear can normally use, although before the lubricating oil of the lubrication system of machine does not lubricate the gear, the quantity of lubricating oil in oil collecting groove 3 on the gear is less, but still can effectually reduce the wearing and tearing that partial teeth of a cogwheel 2 received to the life cycle of this gear can obtain growing.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
