Description
Technical field
The utility model relates to a kind of syndeton, especially relates to a kind of quartz-ceramics roller rod and metal end cover johning knot structure.
Background technology
Quartz-ceramics roller rod is a most important parts in the glass horizontal annealing furnace roller-way, is used for carrying glasswork.Roller rod is through after the retrofit, need be on its termination point casing the metal end cover be beneficial to being connected of roller rod and annealing furnace orbital transmission.
Existing quartz-ceramics roller rod overlaps in the johning knot structure with metal end; Commonly adopt material such as silica gel to connect roller rod termination and metal end cover; Because materials such as silica gel have very strong elasticity and viscosity; Can make the outside surface of roller rod termination and the internal surface bonding of metallic sheath be one simultaneously,, accomplish the excellent rotation of roller in order to carry-over moment.But; When in 300 degree to 700 degree even higher temperature,, silica gel and roller rod and being connected of metal end cover are produced become flexible because the differences in expansion between quartz-ceramics roller rod and metallic sheath is very big; Simultaneously; High temperature uses and can quicken the aging of silica gel, also causes becoming flexible between roller rod and the metallic sheath, influences the article transmission quality.According to measuring and calculating, the termination diameter is the quartz-ceramics roller rod of 65mm, adopt this mode of connection after; Moment of torsion is no more than 150NM when temperature is the 400 degree left and right sides, and when temperature reached the 500 degree left and right sides, moment of torsion sharply descended; Be no more than 80NM, this moment of torsion can not satisfy the requirement of transmission.In addition, this mode of connection requires very high to the silica gel that is adopted, and the price of these silica gel is also very expensive, so increased product cost.
Another kind of syndeton is taked the directly upwards boring in quartz-ceramics roller rod termination, and in a plurality of metallic pin patchholes, metallic pin is connected with the metal end cover again.Relatively poor by mechanical properties such as the hardness of quartz-ceramics, fracture toughness propertyes, metallic pin and quartzy multiple impact in rotation process can make ceramic termination cracking and damage quartz-ceramics roller rod.
Also have a kind of syndeton to take upwards to process concave surface, use key to be connected between quartz-ceramics roller rod and metallic sheath at quartz-ceramics roller rod shaft pertaining.This key mode of connection can guarantee the transmission of moment at high temperature; The phenomenon that gets loose can not appear; But because quartz-ceramics roller rod is very big with metal end inner room expansion coefficient difference, form the gap between the two easily, can not guarantee the centering degree of the excellent and metal end inner room of quartz-ceramics roller at high temperature; Cause the diameter run-out when using under the high temperature, thereby influence articles conveyed quality.
The utility model content
The applicant has carried out research and has improved to above-mentioned problem, and a kind of quartz-ceramics roller rod and metal end cover johning knot structure are provided, and guarantees at high temperature to transmit enough big moment of torsion and reduction manufacturing cost between the quartz-ceramics roller rod and metal end cover.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of quartz-ceramics roller rod and metal end cover johning knot structure; Comprise quartz-ceramics roller rod and metal end cover; Said metal end cover is sleeved on the axle head of said quartz-ceramics roller rod; At least two elastic cylindrical pin symmetries that axially are provided with are inlaid between the mating surface of said quartz-ceramics roller rod axle head and said metal end cover, and half cotter way of said quartz-ceramics roller rod axle head and half cotter way of said metal end cover constitute the cylinder pin hole of the said elastic cylindrical pin of setting-in.
Further:
The inwall of said metal end cover is provided with and holds the glue-line crack, and silica gel is filled in said quartz-ceramics roller rod axle head of bonding and said metal end cover in the said appearance glue-line crack; Said metal end cover middle part is provided with hole for injecting glue, and said hole for injecting glue is communicated with half cotter way that said metal end puts, and the middle part of half cotter way of said quartz-ceramics roller rod axle head is provided with and the corresponding spew groove of said hole for injecting glue.
Said elastic cylindrical pin extends to the end face of said metal end cover.
The technique effect of the utility model is:
Disclosed a kind of quartz-ceramics roller rod of the utility model and metal end cover johning knot structure; The setting-in elastic cylindrical pin is used to transmit moment of torsion between the mating surface of quartz-ceramics roller rod axle head and metal end cover; Avoiding at high temperature, quartz-ceramics roller rod loosening phenomenon occurs with the metal end inner room; Guarantee at high temperature can to transmit enough big moment of torsion between quartz-ceramics roller rod and the metal end cover, reduce the usage quantity of silica gel simultaneously, the reduction manufacturing cost.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Shown in Fig. 1 ~ 6, the utility model comprises quartz-ceramics roller rod 2 and metal end cover 1, and metal end cover 1 is sleeved on the axle head of quartz-ceramics roller rod 2; Three elastic cylindrical pins 3 axially are provided with; Between the axle head that three elastic cylindrical pin 3 symmetries are inlaid in quartz-ceramics roller rod 2 and the mating surface of metal end cover 1, elastic cylindrical pin 3 plays the mechanical attachment effect between the axle head of quartz-ceramics roller rod 2 and metal end overlap 1, be used to transmit moment of torsion; Half cotter way of half cotter way 201 (Fig. 5,6) of the axle head of quartz-ceramics roller rod and metal end cover 1 constitutes the cylinder pin hole of setting-in elastic cylindrical pin 3; The diameter of cylinder pin hole is slightly smaller than the diameter of elastic cylindrical pin 3, and in the present embodiment, elastic cylindrical pin 3 extends to the end face of metal end cover 1; Both make things convenient for elastic cylindrical pin 3 to install, can transmit moment of torsion better again.Elastic cylindrical pin 3 is cylindrical body of a kind of hollow without a head; Axially grooved; Two cephalic pars have chamfering; Can be used for location, connection, fixing etc. between the part, need possess good elasticity and anti-shearing force, its effect has: 1, utilize the good characteristics of its anti-shearing force enough big moment of transmission between quartz-ceramics roller rod 2 and metal end cover 1; 2, can compensate metal end cover 1 expansion at high temperature through corresponding elastic deformation, guarantee centering, avoid quartz-ceramics roller rod 2 diameter run-out to occur.
The inwall of metal end cover 1 is provided with and holds the glue-line crack, and silica gel 4 is filled in axle head and the metal end cover 1 that holds bonding quartz-ceramics roller rod 2 in the glue-line crack; Metal end is overlapped 1 middle part and is provided with hole for injecting glue 5, and hole for injecting glue 5 is communicated with half cotter way on the metal end cover 1, and the middle part of half cotter way 201 of the axle head of quartz-ceramics roller rod 2 is provided with and the corresponding spew groove 6 of hole for injecting glue.Charge into silica gel through hole for injecting glue 5 to the axle head of quartz-ceramics roller rod 2 and the mating surface of metal end cover 1; Because the insertion of elastic cylindrical pin 3 can be blocked silica gel and can't be full of whole appearance glue-line crack; So the middle part at half cotter way 201 of quartz-ceramics roller rod 2 axle heads is offered and hole for injecting glue 5 corresponding spew grooves 6, can let silica gel circulate smoothly.
