5results about How to "Reduce axial stress" patented technology

This utility model provides a monitoring module for a granulator grease heating system, comprising: a base bolted to one side of the granulator spindle box; a positioning support rod welded to one side of the base; a vibration-transmitting slide plate fitted onto the side of the positioning support rod away from the bottom; and a mounting base plate welded to the bottom of the side of the vibration-transmitting slide plate away from the positioning support rod; a damping plate 5 positioned on the left or right side of the top of the mounting base plate; and a sensor threadedly inserted into the center of the side of the damping plate away from the mounting base plate. This utility model employs a two-section damping bracket. One section features a damping plate with a connecting waist hole fitting design for buffering effect, preventing the sensor from breaking compared to rigid fixation. The second section comprises a vibration-transmitting slide plate, a positioning support rod, and a base, transmitting some vibration to the external bracket, reducing the axial stress acting on the hexagonal bolt threaded rod, and preventing the hexagonal bolt from loosening.

The invention discloses a novel micro-channel type cooling structure device for a disc laser. The novel micro-channel type cooling structure device comprises a sealing cover, a heat sink, a crystal, a supporting ring and a vortex-shaped channel. The sealing cover and the shell are made of copper-tungsten alloy vortex-shaped flow channels, the main body material of the vortex-shaped flow channels is diamond, and the vortex-shaped flow channels are realized through an etching process, and the vortex-shaped flow channels have the structural advantages that water inlets are formed in the periphery and water outlets are formed in the center, so that the influence on the crystal surface shape caused by overlarge stress generated on the back surface of a heat sink during collision of a traditional jet flow structure is avoided; the light beam quality is reduced; meanwhile, the four vortex flow channels are combined with local impact, so that the fluid generates strong secondary flow and boundary layer disturbance, the convective heat transfer coefficient is increased, a circular heat source of a light spot with the diameter of 17 mm is well adapted, and compared with a traditional micro-flow-channel structure, the temperature uniformity is greatly improved. The invention has the advantage that the problems of stress deformation and non-uniform heat dissipation existing in large-area sheet crystal heat exchange are solved through a unique bionic flow channel structure.

The application relates to the field of heat exchangers, in particular to a pure counterflow heat exchanger for tube and shell processes, which comprises a front-end tube box, a tube process inlet is fixedly communicated with the outer wall of the top end of the front-end tube box; a fixed tube plate is fixedly communicated with the right end of the front-end tube box; a shell process cylinder is fixedly communicated with the right end of the fixed tube plate, a shell process inlet is fixedly communicated with the top of the right end of the shell process cylinder, a shell process outlet is fixedly communicated with the bottom of the left end of the shell process cylinder; a rear-end tube box is fixedly communicated with the right end of the shell process cylinder; the tube process inlet is arranged at the left end and the tube process outlet is arranged at the right end, so that the same fixed tube plate is prevented from being simultaneously contacted with the inlet medium and the outlet medium and from having an excessively large temperature difference, the heat exchange effect is improved, an expansion joint is further arranged, the tube bundle can freely stretch and shrink along the axial direction, and the axial stress between the tube process and the shell process is reduced.

The utility model discloses an anti-seismic protective corrugated pipe assembly with axial buffer joint structures, which comprises a corrugated pipe main body, external pipelines are arranged on both sides of the corrugated pipe main body, the axial buffer joint structures are arranged between both ends of the corrugated pipe main body and the external pipelines, and a protective structure is arranged outside the corrugated pipe main body. The axial buffering connector structure comprises a first connecting ring, a second connecting ring, a buffering spring and a limiting rod, the first connecting ring is fixedly connected with one end of the corrugated pipe body, the second connecting ring is fixedly connected with an external pipeline, and the two ends of the buffering spring are fixedly connected with the first connecting ring and the second connecting ring respectively. And one end of the limiting rod is fixedly connected with the first connecting ring, and the other end of the limiting rod penetrates through the second connecting ring and extends to the outside, so that the anti-seismic property of the corrugated pipe assembly can be improved, and joint damage caused by axial stress can be effectively avoided.

The utility model relates to an electric roller end sealing structure and a roller conveying line. The technical problem that an existing electric roller end cover is unreasonable in sealing design is solved. The electric roller end sealing structure comprises an end cover which is of a cylindrical structure, and a central cavity, a rotating cavity and a roller cavity which are axially arranged in a stepped mode are sequentially arranged in the end cover outwards in the radial direction of a central shaft; the positioning mandrel is axially arranged in the end cover in a penetrating mode, one end of the positioning mandrel penetrates out of the outer side of the end cover, and an outer oil seal connected to the circumferential outer wall of the positioning mandrel in a sleeving mode is embedded in the bottom of the center cavity; the bearings are located and embedded in the rotating cavity, and the bearings are connected to the circumferential outer wall of the locating mandrel in a sleeving mode; and the supporting outer cylinder is fixedly connected with the end cover, and the roller cavity is an annular groove which is concave in the axial direction. According to the end sealing structure of the electric roller, the axial pressure of the outer oil seal is reduced, the mutual influence is reduced, and the overall sealing performance of the electric roller is improved.
