When the jackscrew passes through the support sleeve 130 and is connected with the high-temperature-resistant nut in the countersunk hole, under the action of external force, the jackscrew moves along the radial direction of the axis of the roller body 110 along the roller body 110, and under the action of reaction force, the high-temperature-resistant nut sleeved on the jackscrew can move in the direction back from the axis of the roller body 110, and because the opening cross section of the support sleeve 130 is smaller than that of the countersunk hole, the nut moves in the direction departing from the axis of the roller body 110 and can be abutted against the support sleeve 130, namely, a part of the jackscrew is positioned in the through hole of the support sleeve 130, a part of the jackscrew is positioned in the nut of the countersunk hole, and the jackscrew is wrapped by the nut in the countersunk hole, so that the connection of.

L1 is less than d/2, and on the same cross section of the roller body 110, a plurality of counter bores can be arranged in the radial direction so as to limit the stable connection between the support sleeve 130 and the roller body 110.

(2) S2 is less than S1, L1 is less than d/2, the nut is placed in the countersunk hole (not connected, the roller body 110 falls after rotating 180 degrees, and the specification of the nut is smaller than the size of the countersunk hole, namely the height of the nut is far smaller than the depth of the mounting part 112).

When the jackscrew (with screw thread) passes through the support sleeve 130 and is connected with the high temperature resistant nut in the countersunk hole, the connection between the limit support sleeve 130 and the roller body 110 is realized. The top thread is partially positioned in the through hole 132 of the support sleeve 130, partially positioned in the nut of the countersunk hole, and one end of the top thread is wrapped by the nut in the countersunk hole, so that the connection of the limit support sleeve 130 and the roller body 110 is realized.

The depth L of the countersunk hole formed on the carrier roller can be d/2 < L < d, and is only connected with one through hole 132 of a pair of through holes 132 (corresponding up and down) of the support sleeve 130.

(3) The depth L of the countersunk hole formed in the roller body 110 can be d/2 < L < d, and is connected with only one through hole 132 of a pair of through holes 132 (corresponding up and down) of the support sleeve 130.

Further, the specification of the nut is M, for example: m6 (nominal diameter of 6mm), M8 (nominal diameter of 6mm), one skilled in the art can select a nut of the appropriate size depending on the condition of the mounting portion 112.

Example 15:

according to a second aspect of the embodiments of the present invention, the present invention provides a heat treatment apparatus, including: sintering furnace; a plurality of idler assemblies 100 as provided in any one of embodiments 1 to 14 above, the idler assemblies 100 being rotatably laid side by side in a shaft of a sintering furnace.
