Abstract
The utility model discloses a device adopting a groove metal piece for deforming clasping transmission and preventing a shaft sleeve from being damaged by screws. The device comprises a transmission seat (2), a metal corrugated pipe (6) and a movable ring (8), wherein the transmission seat (2) is arranged at the periphery of a pump shaft (9), a corrugated pipe seat (5) is connected with the transmission seat (2) by a hexagon socket head cap screw (1) which is arranged on the transmission seat (2), the corrugated pipe seat (5) is connected with the movable ring (8) by the metal corrugated pipe (6), the movable ring (8) is connected on a movable ring seat (7), a metal ring is arranged between the hexagon socket head cap screw (1) and the pump shaft (9) and is sleeved at the outer part of the pump shaft, and the metal ring (3) is connected with the corrugated pipe seat (5) by a flexible graphite sealing ring (4). The device has the beneficial effects of more reliable mechanical sealing and transmission as well as longer service life.
Description
Technical field
The utility model relates to a kind of various mechanical devices that lean on screw-driving transmission occasion that are suitable for, and particularly a kind ofly adopts the distortion of groove metalwork to hold transmission tightly and prevents the device of screw damage axle sleeve.
Background technique
The occasion of pump is used in chemical plant etc., because environment and safety requirement, every pump has all used mechanical seal.Owing to the replacing or the reasons such as light maintenance, overhaul and other part replacing of mechanical seal, all can be repeatedly on pump shaft, twist screw, when screw material hardness during greater than the pump shaft material hardness; Tighten screw and can cause the damage of pump shaft; Add and use the environment overwhelming majority of mechanical seal to have severe corrosive, hinder the pump shaft surface, form fine recesses because screw is twisted; Can accelerate the corrosion of medium, make the pump shaft surface occur many because the damage that screw causes to component.If change axle, not only cause more expense, more have influence on the efficient of production.
The model utility content
To the defective of existing machinery sealing, the utility model provides a kind of and has adopted the distortion of groove metalwork to hold transmission tightly and prevent the device of screw damage axle sleeve.
To achieve these goals, the measure taked of the utility model is:
A kind ofly adopt groove metalwork distortion to hold transmission tightly and prevent the device of screw damage axle sleeve; Comprise and be arranged on pump shaft peripheral retainer, metal bellows and rotating ring; The hexagon socket cap head screw that is provided with on the retainer links together corrugated header and retainer; Corrugated header links to each other with rotating ring on being connected rotating seat through metal bellows; Between hexagon socket cap head screw and pump shaft, be provided with a metal ring that is enclosed within the pump shaft outside, metal ring links to each other with corrugated header through the Expanded graphite seal ring;
Said metal ring is provided with the groove that staggers with the hexagon socket cap head screw position.
The beneficial effect of the utility model: adopt the groove metal ring to place between pump shaft and the screw, prevent to tighten screw and cause the pump shaft damage; Groove on metal ring utilizes screw metal ring is twisted distortion and to hold tightly on pump shaft, and the characteristics of utilizing the area transmission to be superior to a transmission make the mechanical seal device transmission more reliable.
Description of drawings
The structural representation of Fig. 1, the utility model;
The groove ring schematic representation of Fig. 2, the utility model.
Embodiment
A kind ofly adopt groove metalwork distortion to hold transmission tightly and prevent the device of screw damage axle sleeve; Comprise the retainer 2, metal bellows 6 and the rotating ring 8 that are arranged on pump shaft 9 peripheries; The hexagon socket cap head screw 1 that is provided with on the retainer 2 links together corrugated header 5 and retainer 2; Corrugated header 5 links to each other with rotating ring 8 on being connected rotating seat 7 through metal bellows 6; Between hexagon socket cap head screw 1 and pump shaft 9, be provided with a metal ring 3 that is enclosed within the pump shaft outside, metal ring 3 links to each other with corrugated header 5 through Expanded graphite seal ring 4; Said metal ring 3 is provided with the groove 10 that staggers with hexagon socket cap head screw 1 position.
When the Sealing of groove metal ring device is installed, should notice that groove should be avoided in the position of screw correspondence; In use; Rotating screw 1; Metal ring 3 is twisted distortion and held tightly on pump shaft 9, and the characteristics of utilizing the area transmission to be superior to a transmission make the mechanical seal device transmission more reliable, and metal ring 3 is between hexagon socket cap head screw 1 and pump shaft 9; Hexagon socket cap head screw 1 just can not contact with pump shaft 9, can not damage pump shaft 9.
The beneficial effect of the utility model: adopt the groove metal ring to place between pump shaft and the screw, prevent to tighten screw and cause the pump shaft damage; Groove on metal ring utilizes screw metal ring is twisted distortion and to hold tightly on pump shaft, and the characteristics of utilizing the area transmission to be superior to a transmission make the mechanical seal device transmission more reliable.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in related domain.
