Abstract
The utility model discloses an oil leakage prevention gear sleeve. Including setting up the gear sleeve body in bevel gear extension department, gear sleeve body outer wall circumference is provided with a plurality of water conservancy diversion sand grips. The utility model discloses an add the gear sleeve, be connected gear sleeve and bevel gear cooperation, reduce and the aluminium parts between the clearance, promote dustproof effect to the air current that produces through fan blade formula structure loops back the oil that leaks, thereby avoids the oil leak.
Description
Technical Field
The utility model belongs to the technical field of electric tool technique and specifically relates to leak protection oil gear cover.
Background
An angle grinder, also called a grinder or a disc grinder, is a portable electric tool for cutting and grinding glass fiber reinforced plastics, and is mainly used for cutting, grinding and brushing metal and stone materials.
In the existing angle grinder, the rotation direction is usually converted through a bevel gear structure, in the actual use process, the oil leakage phenomenon is easy to occur at the position, the oil quantity at the position of a rotor is insufficient, and the damage to the internal structure is easy to cause due to untimely treatment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough to among the prior art, provide leak protection oil gear sleeve, it is through addding the gear sleeve, be connected gear sleeve and bevel gear cooperation, reduce and the aluminium part between the clearance, promote dustproof effect to the air current that produces through fan blade formula structure loops back the oil of leaking, thereby avoids the oil leak.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: leak protection oil gear cover, including setting up the gear cover body in bevel gear extension department, gear cover body outer wall circumference is provided with a plurality of water conservancy diversion sand grips.
In the above scheme, preferably, the water conservancy diversion sand grip circumference and even setting are in on the outer wall of gear sleeve body. The even air current body that sets up the water conservancy diversion sand grip in circumference and guarantee its production has stability, helps promoting leak protection oil effect.
In the above scheme, preferably, the setting angle of the flow guide protruding strip corresponds to the setting angle of the gear teeth of the bevel gear. Prevent to lead to the air current body confusion that the gear sleeve produced because of the hindrance of the teeth of a cogwheel of bevel gear, guarantee its stability.
In the above scheme, preferably, a plurality of grooves are formed in the side surface of the gear sleeve body facing the bevel gear. Increase this department gas and hold the volume, strengthen the intensity of gas-liquid, increase leak protection oil effect.
In the above scheme, preferably, the groove bodies are circumferentially and uniformly arranged on the side surface of the gear sleeve body. Guarantee the gaseous stable distribution of this department, strengthen the leak protection oil effect.
In the above scheme, preferably, the gear sleeve body is arranged at the bevel gear extension portion in an interference fit manner and rotates along with the rotation of the bevel gear. Guarantee gear sleeve and bevel gear synchronous revolution, strengthen the leak protection oil effect.
The utility model has the advantages that: the utility model discloses simple structure has dustproof, the effect of leak protection oil, and it is through addding the gear sleeve, is connected the gear sleeve with the bevel gear cooperation, reduce and the aluminium part between the clearance, promote dustproof effect to the air current that produces through fan blade formula structure loops back the oil of leaking, thereby avoids the oil leak.
Drawings
Fig. 1 is a schematic view of the present invention.
Fig. 2 is the matching schematic diagram of the present invention and bevel gears.
Fig. 3 is an exploded view of the utility model in use.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1-3, the oil leakage prevention gear sleeve comprises a gear sleeve body 1 disposed at an extension 21 of a bevel gear 2 toward a rotor 3, preferably, the gear sleeve body 1 is disposed at the extension 21 of the bevel gear 2 in an interference fit manner and rotates with the rotation of the bevel gear 2.
The outer wall circumference of gear sleeve body 1 is provided with a plurality of water conservancy diversion sand grips 11, and is preferred, the angle that sets up of water conservancy diversion sand grip 11 with the angle that sets up of the teeth of a cogwheel 22 of bevel gear 2 is corresponding, and its circumference and even setting are in on the outer wall of gear sleeve body 1.
The setting direction of the flow guide convex strip 11 is opposite to the setting direction of the blades on the air guide ring 4, and the flow guide convex strip is arranged in an inclined upward direction from one side facing the bevel gear 2 to the other side.
The side face, facing the bevel gear 2, of the gear sleeve body 1 is provided with a plurality of groove bodies 12, and the groove bodies 12 are circumferentially and uniformly arranged on the side face of the gear sleeve body 1. Increase this department gas and hold the volume, guarantee this department gaseous stable distribution, strengthen the intensity of gas-liquid, increase leak protection oil effect.
The utility model discloses an add in bevel gear 2 department rather than synchronous pivoted gear sleeve, reduce and the motor casting between the clearance to promote dustproof effect, simultaneously, be provided with water conservancy diversion sand grip 11 because of circumference on the gear sleeve body 1, make it produce the gas fluid when rotatory, this gas fluid can be enough with oil toward loopback, thereby avoid the emergence of oil leak phenomenon.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
