Technical Field
The invention relates to the field of end covers, in particular to a water-cooled motor end cover.
Background
The end cover is a rear cover arranged behind the motor and other machine shells, is commonly called an end cover, and is used for fixing the whole motor through a rotating shaft. The general appearance of motor end cover on the existing market all has a lot of unsmooth holes for strengthen the motor heat dissipation, but this kind of mode radiating effect is not high.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to overcome the defects of the prior art and provides a water-cooled motor end cover.
The technical scheme is as follows: the utility model provides a water-cooled motor end cover, includes the end cover body, the end cover body is connected with a plurality of fixed ears, fixed ear is equipped with mounting hole, the inboard of end cover body is equipped with a plurality of strengthening ribs, the outside of end cover body is equipped with the annular fin of a plurality of rings, the end cover body is equipped with the centre bore that is used for installing the bearing, the inside of end cover body still is equipped with spiral helicine water-cooling channel, water-cooling channel's one end is the water inlet, one end is the delivery port, spiral water-cooling channel's total radian is greater than 360 x (N-1), N is the quantity of fin.
Further, the total radian of the spiral water-cooling channel is less than 360 × (N +1), and N is the number of the radiating fins, so that the water-cooling channel and the radiating fins are distributed correspondingly.
Further, the reinforcing ribs are distributed in a radial mode, so that the whole end cover can be integrally reinforced.
Further, the number of the reinforcing ribs is more than or equal to 6.
Further, the number of the radiating fins is more than or equal to 3, and the plurality of radiating fins are distributed in a concentric circle mode, so that the radiating fins can be uniformly distributed.
Furthermore, the number of the fixing lugs is more than or equal to 4, so that the end cover and the motor can be more stable when being fixed.
Has the advantages that: the motor end cover is provided with the radiating fins matched with the water cooling channels, so that heat in the running process of the motor can be effectively discharged, the radiating effect is good, and meanwhile, the motor end cover is reinforced by the reinforcing ribs.

Detailed Description
Reference numerals: 1, an end cover body; 1.1 fixing the ear; 1.11 installing a through hole; 1.2 a central hole; 2, radiating fins; 3, reinforcing ribs; 4 water cooling channel.
The utility model provides a water-cooled motor end cover, includes end cover body 1, end cover body 1 is connected with a plurality of fixed ears 1.1, fixed ear 1.1 is equipped with installation through-hole 1.11, end cover body 1's inboard is equipped with a plurality of strengthening ribs 3, end cover body 1's the outside is equipped with a plurality of ring form fin 2, end cover body 1 is equipped with centre bore 1.2 that is used for installing the bearing, end cover body 1's inside still is equipped with spiral helicine water-cooling passageway 4, water-cooling passageway 4's one end is the water inlet, one end is the delivery port, spiral water-cooling passageway's total radian is greater than 360 x (N-1), N is the quantity of fin 2.
The total radian of the spiral water-cooling channel 4 is less than 360 x (N +1), and N is the number of the radiating fins 2. The reinforcing ribs 3 are distributed in a radial shape. The number of the reinforcing ribs 3 is more than or equal to 6. The number of the radiating fins 2 is more than or equal to 3, and the plurality of radiating fins 2 are distributed in a concentric circle. The number of the fixing ears 1.1 is more than or equal to 4.
According to the motor end cover, the radiating fins are arranged on the outer side of the end cover, heat generated by the radiating fin motor is discharged, the water cooling channel is arranged corresponding to the radiating fins, cold water in the channel absorbs the heat discharged by the radiating fins, water flow in the water cooling channel is circulated to always keep low water temperature, and the heat generated by the motor in operation can be effectively dissipated. The strengthening rib that the end cover inboard was equipped with for the motor end cover is more firm, only needs to fix the end cover with the motor through the installation through-hole on the fixed ear during the use. The motor end cover disclosed by the invention is good in stability and strong in heat dissipation performance.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
