[0022] DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0024] This embodiment provides a heat dissipation sleeve sleeved on the bearing, the heat dissipation sleeve connects the bearing box and the cooling device, and uses the coolant in the cooling device of the bearing box to dissipate heat from the bearing.

[0025] Specifically, Figure 1-3 As shown, this embodiment is composed of an inner ring 1 and an outer ring 2 installed by coaxial welding. The inner ring 1 and the outer ring 2 are installed by shrink sleeve after interference fit, and then connected into a whole by welding. The bearing is located on the inner side of the inner ring 1. The inner ring 1 and the outer ring 2 are made of heat-conducting metal materials, such as steel, copper, etc., so as to enhance the heat dissipation effect. A heat dissipation groove is arranged on the outer peripheral side of the inner ring 1. The heat dissipation groove is in sealed contact with the inner wall of the outer ring 2. The heat dissipation groove includes an annular groove 12 and a linear groove 13. The annular groove 12 is connected to the linear groove 13. A liquid inlet 3 and a liquid outlet 4 are arranged at the welding groove at one end. The cooling interface of the bearing box is connected to the liquid inlet 3, and the cooling device is connected to the liquid outlet 4. Either one of the liquid inlet 3 and the liquid outlet 4 is connected to the annular groove 12, and the other is connected to the linear groove 13. That is, the liquid inlet 3 and the liquid outlet 4 are arranged on the same end face of the heat dissipation sleeve, and the other end face of the heat dissipation sleeve needs to contact with the spindle in actual processing.

[0026] In this embodiment, eight positioning grooves 5 are provided at both ends of the inner ring 1 and the outer ring 2, and the eight positioning grooves 5 are equally distributed along the end faces of the inner ring 1 and the outer ring 2. The positioning grooves 5 are used for positioning and installing the heat dissipation sleeve on the bearing box.

[0027] like Figure 4-5 As shown, inner ring welding grooves 11 are provided on the outer ring side at both ends of the inner ring 1, and outer ring welding grooves 21 are provided on the inner ring side at both ends of the outer ring 2. The inner ring welding grooves 11 and the outer ring welding grooves 21 together constitute welding grooves, and the inner ring 1 and the outer ring 2 are connected by welding at the welding grooves.

[0028] In one embodiment, the annular groove 12 includes a plurality of unclosed annular groove monomers, the openings of the plurality of annular groove monomers are connected at the ends, and the linear groove 13 is parallel to the axial direction of the inner ring 1 and passes through the openings of the plurality of annular groove monomers, that is, a linear groove 13 is firstly machined axially on the outer peripheral side of the inner ring 1, and then an annular groove monomer is machined circumferentially at one end of the linear groove 13, and when the annular groove monomer is about to touch the linear groove 13, it turns and another parallel annular groove monomer is machined, until the outer peripheral side of the inner ring 1 is almost covered, and the linear groove 13 and the annular groove 12 have only one flow channel as a whole, thereby ensuring that the coolant can fully flow through the outer peripheral side of the inner ring 1, and enhancing the heat dissipation effect on the bearing. The design of using the linear groove 13 in conjunction with the annular groove 12 is mainly considered to be that in some cases, there is an obstacle at one end of the heat dissipation sleeve, and the liquid inlet 3 and the liquid outlet 4 can only be set at the other end, and the linear groove 13 in conjunction with the annular groove 12 can well achieve that the coolant enters and exits at the same end and flows through the entire circumference of the heat dissipation sleeve.

[0029] like Figure 6As shown, the right end of the linear groove 13 is connected to the annular groove monomer at the rightmost edge of the annular groove 12, and the left end of the linear groove 13 and the annular groove monomer at the leftmost edge of the annular groove 12 are respectively connected to one of the liquid inlet hole 3 or the liquid outlet hole 4. A notch is provided at the annular groove monomer at the left end of the annular groove 12, and the notch faces left and is almost flush with the left end of the linear groove 13. If the notch is connected to the liquid inlet hole 3, the left end of the linear groove 13 is connected to the liquid outlet hole 4; if the notch is connected to the liquid outlet hole 4, the left end of the linear groove 13 is connected to the liquid inlet hole 3.

[0030] In one embodiment, the heat dissipation grooves may also be arranged on the inner side of the outer ring 2 , but it is not as convenient to process as on the outer peripheral side of the inner ring 1 .
