Description

Technical Field

[0001] This utility model relates to the field of roller sand making machine technology, and in particular to a roller press bearing seat structure with a cooling system. Background Technology

[0002] Roller sand making machines typically include fixed rollers and movable rollers. Material is fed from above the two rollers, continuously carried into the space between them by the compression rollers, and discharged from the bottom of the machine at an ideal particle size. The relative movement of the two rollers crushes stones into sand. Chinese patent document CN202021220681X, authorized and announced on April 13, 2021, entitled "A Double Roller Sand Making Machine," includes a frame, a first pressing roller, a second pressing roller, and a drive motor. A pressing channel is formed between the first and second pressing rollers. The first pressing roller is rotatably connected to the frame, and the drive motor is connected to the frame to drive the first pressing roller to rotate. The frame has several support legs, each including a base plate, a lifting plate, a top plate, and a column arranged sequentially from bottom to top. The base plate has a positioning ring. A shortcoming of existing roller sand making machines is that they cannot cool the outer ring of the bearings through a circulating cooling system. Utility Model Content

[0003] The present invention aims to provide a roller press bearing housing structure with a cooling system that can cool the bearings, thus solving the problem that existing sand making machine bearings cannot be adequately cooled.

[0004] The above technical problems are solved by the following technical solution: a roller press bearing housing structure with a cooling system, comprising a bearing housing with bearing mounting holes, characterized in that the bearing housing has a coolant inlet channel and a coolant return channel extending circumferentially along the bearing mounting holes; the inlet end of the coolant inlet channel has a coolant inlet penetrating the surface of the bearing housing; the outlet end of the coolant return channel has a coolant outlet penetrating the surface of the bearing housing; the outlet end of the coolant inlet channel is connected to the inlet end of the coolant return channel through a connecting channel; the bearing housing is made of a thermally conductive material. In use, coolant is input from the coolant inlet end, flows sequentially through the coolant inlet channel, the connecting channel, and the coolant confluence channel, and then flows out from the coolant outlet. During this circulation process, the coolant cools the bearing housing, thereby achieving bearing cooling.

[0005] Preferably, the coolant inlet channel and coolant return channel are distributed along the axial direction of the bearing mounting hole. This allows the coolant inlet channel and coolant return channel to be close to the circumferential surface of the bearing mounting hole, thereby improving the cooling effect.

[0006] Preferably, the connecting channel extends axially along the bearing mounting hole. This reduces the likelihood of wall breakage.

[0007] Preferably, the connecting channel extends through the surface of the bearing housing to form a sand discharge port, which is sealed by a plug. During the casting and fabrication of the bearing housing, the sand core forming the connecting channel can support the sand core forming the coolant inlet and coolant return channels, facilitating the removal of the sand core.

[0008] Preferably, the coolant inlet and coolant outlet are located on the same end face of the bearing housing. This facilitates connection to a coolant source.

[0009] Preferably, the coolant inlet channel and the coolant return channel are located on the same arc surface, and the axis of the arc surface is parallel to the axis of the bearing mounting hole. This improves the cooling effect.

[0010] Preferably, the coolant inlet has a straight structure, extending axially along the bearing mounting hole. The coolant outlet includes a first straight end connected to the outlet end of the coolant return channel at one end and a second straight segment connected to the first straight segment at the other end. The first straight segment penetrates the surface of the bearing housing to form a coolant outlet sand discharge port, which is sealed by a coolant outlet plug. The second straight segment penetrates the end face of the bearing housing and extends axially along the bearing mounting hole. During the casting of the bearing housing, the sand core forming the coolant inlet can support the sand core forming the coolant input channel, and the sand core forming the second straight segment can support the sand core forming the coolant return channel. Sand discharge is convenient during both the coolant inlet / outlet and the sand discharge port.

[0011] Preferably, the first straight segment and the coolant return channel are located on the same plane. During the casting process, the sand core forming the first straight segment is less likely to break.

[0012] Preferably, the coolant inlet channel and the coolant return channel are parallel, and the coolant inlet channel is perpendicular to the axis of the bearing mounting hole. This results in a high yield rate during manufacturing and good consistency in cooling effect across the inner circumference of the bearing housing.

[0013] Preferably, the coolant inlet channel has a flat opening shape, and its opening area gradually increases from the inlet to the outlet. The width of the coolant inlet channel is axial to the bearing mounting hole, and its thickness is radial to the bearing mounting hole. Similarly, the coolant return channel has a flat opening shape, and its opening area gradually increases from the inlet to the outlet. The width of the coolant return channel is axial to the bearing mounting hole, and its thickness is radial to the bearing mounting hole. The opening area at the outlet of the coolant inlet channel is smaller than the opening area at the inlet of the coolant return channel. This ensures consistent cooling performance across the inner circumference of the bearing housing.

[0014] The beneficial effects of this invention are: the cooling water can circulate fully, thereby fully cooling the bearing housing, and thus achieving cooling of the bearing, especially the outer ring of the bearing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1, see Figure 1A roller press bearing housing structure with a cooling system includes a bearing housing 2 with a bearing mounting hole 1. The bearing housing has a coolant inlet channel 3 and a coolant return channel 4 extending circumferentially along the bearing mounting hole. The inlet end of the coolant inlet channel has a coolant inlet 5 penetrating the surface of the bearing housing, and the outlet end of the coolant return channel has a coolant outlet 6 penetrating the surface of the bearing housing. The inlet and outlet can be reversed for the same purpose. The outlet end of the coolant inlet channel is connected to the inlet end of the coolant return channel via a connecting channel 7. The bearing housing is made of a thermally conductive material, specifically a metal casting. In use, coolant is input from the coolant inlet end, flows sequentially through the coolant inlet channel, the connecting channel, and the coolant confluence channel, and then flows out from the coolant outlet. During this circulation process, the coolant cools the bearing housing, thereby cooling the bearing.

[0019] The coolant inlet and return channels are distributed axially along the bearing mounting hole. Specifically, the coolant inlet and return channels are located on the same arc surface, and the axis of the arc surface is parallel to the axis of the bearing mounting hole. The coolant inlet and return channels are parallel, and the coolant inlet channel is perpendicular to the axis of the bearing mounting hole. The connecting channel extends axially along the bearing mounting hole. The connecting channel passes through the axial end face of the bearing housing to form a sand discharge port, which is sealed by a connecting channel plug 8. The coolant inlet and coolant outlet are located on the same end face of the bearing housing. This facilitates connection to a coolant source. The coolant inlet has a straight structure and extends axially along the bearing mounting hole. The coolant outlet includes a first straight end 9 connected at one end to the outlet end of the coolant return channel and a second straight segment 10 connected at one end to the first straight segment. The first straight segment penetrates the surface of the bearing housing to form a coolant outlet sand discharge port, which is sealed by a coolant outlet plug 11. The second straight segment penetrates the end face of the bearing housing to achieve coolant output, and extends axially along the bearing mounting hole. The first straight segment and the coolant return channel are located on the same plane.

[0020] Example 2 differs from Example 1 in that: the coolant inlet channel has a flat opening shape, and the opening area gradually increases from the inlet end to the outlet end. The width direction of the coolant inlet channel is the axial direction of the bearing mounting hole, and the thickness direction is the radial direction of the bearing mounting hole. The coolant return channel also has a flat opening shape, and the opening area gradually increases from the inlet end to the outlet end. The width direction of the coolant return channel is the axial direction of the bearing mounting hole, and the thickness direction is the radial direction of the bearing mounting hole. The opening area at the outlet end of the coolant inlet channel is smaller than the opening area at the inlet end of the coolant return channel.
