Description

Technical Field

[0001] The utility model relates to the technical field of ceramic balls, in particular to a spliced ​​zirconia ceramic ball. Background Art

[0002] Zirconia ceramic balls exhibit high strength and toughness at room temperature, excellent wear resistance, high temperature and corrosion resistance, high rigidity, and are non-magnetic. At 600°C, their strength and hardness remain virtually unchanged. Their density is 6.00g / cm³, and their thermal expansion coefficient is close to that of metal, allowing them to be used in conjunction with metals. They are suitable for use in bearings, seals, and other applications.

[0003] The density of zirconia ceramic balls is slightly lower than that of steel. In special circumstances, solid zirconia ceramic balls are still heavy. Therefore, a spliced ​​zirconia ceramic ball is needed to reduce its weight. Utility Model Content

[0010] The utility model has the following beneficial effects:

[0011] In the utility model, grooves and protrusions are respectively provided on the left hemisphere and the right hemisphere. When injecting glue, molten resin or industrial glue is injected into the first glue groove on the protrusion through the glue injection hole. Under the action of the through hole between the first glue groove and the second glue groove, the molten resin or industrial glue enters the second glue groove. During the glue injection process, the right hemisphere is rotated slowly and uniformly, thereby driving the first glue groove and the second glue groove to rotate, making the glue injection more uniform and the connection effect between the left hemisphere and the right hemisphere better.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1-5The utility model embodiment is a spliced ​​zirconia ceramic ball, which includes a left hemisphere 1 and a right hemisphere 2. The left hemisphere 1 and the right hemisphere 2 are respectively provided with a groove 11 and a protrusion 12 on the side close to each other. The protrusion 12 is slidably connected to the groove 11 and is adapted to the groove 11. The groove 11 and the protrusion 12 are both annularly arranged. A glue injection hole 3 is provided on the left hemisphere 1, and the glue injection hole 3 is interconnected with the groove 11. The inner and outer sides of the protrusion 12 are respectively provided with a first glue groove 121 and a second glue groove 122. The first glue groove 121 is located at the second glue groove 122. On the outside, a through hole is provided between the first glue groove 121 and the second glue groove 122. When injecting glue, molten resin or industrial glue is injected into the first glue groove 121 on the protrusion 12 through the glue injection hole 3. Under the action of the through hole between the first glue groove 121 and the second glue groove 122, the molten resin or industrial glue enters the second glue groove 122. During the glue injection process, the right hemisphere 2 is rotated slowly and uniformly, thereby driving the first glue groove 121 and the second glue groove 122 to rotate, making the glue injection more uniform and improving the connection effect between the left hemisphere 1 and the right hemisphere 2;

[0023] A spherical support net 4 is provided between the left hemisphere 1 and the right hemisphere 2. The spherical support net 4 is made of metal wire. A sponge net 5 is fixedly connected to the spherical support net 4. The sponge net 5 is arranged in a grid shape. A metal sheet 6 is provided in the middle of the sponge net 5. A centrifugal ball 7 is provided in the middle of the sponge net 5. The sponge net 5 and the metal sheet 6 added inside the left hemisphere 1 and the right hemisphere 2 are used to cool the zirconia ceramic ball. The setting of the centrifugal ball 7 can squeeze the sponge net 5 and the metal sheet 6 when the zirconia ceramic ball rotates, so that the sponge net 5 and the metal sheet 6 fit better with the inner wall of the zirconia ceramic ball, thereby improving the cooling effect.

[0024] Working principle: When in use, first place the spherical support net 4, sponge net 5 and centrifugal ball 7 between the left hemisphere 1 and the right hemisphere 2, then slide the bump 12 on the right hemisphere 2 into the groove 11 on the left hemisphere 1, and then inject molten resin or industrial glue into the first glue groove 121 on the bump 12 through the glue injection hole 3. Under the action of the through hole between the first glue groove 121 and the second glue groove 122, the molten resin or industrial glue enters the second glue groove 122. During the glue injection process, rotate the right hemisphere 2 slowly and uniformly, thereby driving the first glue groove 121 and the second glue groove 122 to rotate, so that the glue injection is more uniform and the connection effect between the left hemisphere 1 and the right hemisphere 2 is better.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
