Abstract
The utility model discloses a high and low speed roller driven tooth-wedge belt tension device of a pneumatic flour mill. A pneumatic flour mill body bearing beam is provided with an eccentric shaft; the eccentric shaft is fixed on the mill body bearing beam by a clamping bolt and a clamping block; a tension pulley is arranged on the eccentric shaft; one end of an annular tooth-wedge belt is sleeved inside the tension pulley, while the other end of the annular tooth-wedge belt is sleeved in a high-speed roller multi-wedge belt pulley; and the outer surface of the annular tooth-wedge belt is wound on a part of the outer surface of a low-speed tooth-wedge belt pulley. The high and low speed roller driven tooth-wedge belt tension device has the characteristics of being simple in structure, convenient to use and adjust and capable of ensuring the precision of speed ratio transmission of the tooth-wedge belt in a driving process, can effectively prevent the tension of the tooth-wedge belt from being influenced by the aging, the strength reduction and the deformation of a tension spring, ensure the normal work of the pneumatic flour mill and the precision of speed-ratio transmission, prolong the service lives of the tooth-wedge belt and a tension pulley bearing, and can be widely used for various flour mills or ball mills.
Description
Technical field
The utility model relates to the parts of pneumatic flour mill, and what be specifically related to is pneumatic flour mill speed roller transmission toothed wedge belt tensioning apparatus.
Background technology
The steady operation condition of pneumatic flour mill is its key factor that reaches design work efficient, and the toothed wedge belt strainer of speed roller transmission mechanism is the influence factor that its assurance pneumatic flour mill accurately transmits speed ratio, operate as normal.In existing pneumatic flour mill; What the toothed wedge belt strainer of speed roller transmission mechanism used is spring take-up; This makes pneumatic flour mill have following shortcoming: 1, spring is a kind of flexible structure, so that toothed wedge belt exist to be opened is not tight, and in pneumatic flour mill work; If the toothed wedge belt degree of tightness constantly changes, will cause that then the grinding roller lock is apart from variation; 2, spring in use for some time, the intensity of spring, elastic force will descend to some extent, deform easily, cause the trouble in the use to the user; If 3, toothed wedge belt often is in half tensioning state, will have a strong impact on the service life of toothed wedge belt.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure; Use and easy to adjust; Cost is low; Can guarantee the toothed wedge belt accuracy that speed ratio transmits in transmission process, overcome a kind of pneumatic flour mill speed roller transmission toothed wedge belt tensioning apparatus of the above-mentioned defective of existing pneumatic flour mill speed roller transmission toothed wedge belt tensioning existence simultaneously.
In order to overcome the deficiency of prior art; The technical scheme of the utility model is to solve like this: a kind of pneumatic flour mill speed roller toothed wedge belt transmission tensioning apparatus comprises speed polywedge bet wheel, slow roller profile of tooth belt wheel, annular toothed wedge belt, regulating wheel, fishbolt, clamp, eccentric shaft, body carrier bar; The special character of the utility model is on the said pneumatic flour mill body or an eccentric shaft is installed on the carrier bar that this eccentric shaft is through fishbolt and lean on clamp that eccentric shaft is fixed on body or the carrier bar; A regulating wheel is installed on the said eccentric shaft; Said annular toothed wedge belt one end is inserted in regulating wheel, and the annular toothed wedge belt other end is inserted in fast roller polywedge bet wheel, and said annular toothed wedge belt outer surface was scratched the part outer surface of slow roller profile of tooth belt wheel.
The tooth of the inner surface of said annular toothed wedge belt is semicircular arc or triangle.
Said regulating wheel is provided with the hole to bearing filling lubricating oil.
The utility model compared with prior art has simple in structurely, uses and easy to adjust; Cost is low, can guarantee the characteristics of the toothed wedge belt accuracy that speed ratio transmits in transmission process, overcomes existing pneumatic flour mill speed roller transmission toothed wedge belt tensioning simultaneously and has defective; Can effectively prevent because tensioning spring is aging; Intensity descends and is out of shape, and influences the tensioning of toothed wedge belt, guarantees the accuracy that pneumatic flour mill operate as normal and speed ratio transmit; Prolong the service life of toothed wedge belt and the service life of tension wheel shaft bearing simultaneously, be widely used in various flour mills or the ball mill.

The specific embodiment
Accompanying drawing is the embodiment of the utility model.
Be described further below in conjunction with the content of accompanying drawing invention:
With reference to Fig. 1, shown in Figure 2; Pneumatic flour mill speed roller transmission toothed wedge belt tensioning apparatus; This device comprises speed polywedge bet wheel, slow roller profile of tooth belt wheel, annular toothed wedge belt, regulating wheel, fishbolt, clamp, eccentric shaft, body carrier bar; An eccentric shaft 7 is installed on said pneumatic flour mill body or the carrier bar 8, and this eccentric shaft 7 is fixed on eccentric shaft 7 on body or the carrier bar 8 through fishbolt 5 and clamp 6; A regulating wheel 4 is installed on the said eccentric shaft 7; Said annular toothed wedge belt 3 one ends are inserted in regulating wheel 4, and annular toothed wedge belt 3 other ends are inserted in fast roller polywedge bet wheel 1, and said annular toothed wedge belt 3 outer surfaces were scratched the part outer surface of slow roller profile of tooth belt wheel 2.
The tooth of the inner surface of said annular toothed wedge belt is semicircular arc or triangle.
Said regulating wheel 4 is provided with the hole to bearing filling lubricating oil.
When needs adjustment toothed wedge belt 3 degrees of tightness, through unclamping the fishbolt 5 on the clamp 6, eccentric rotation axis 7 adjustment eccentric positions can carry out tensioning to toothed wedge belt 3 again, tighten fishbolt 5 after the tensioning again, reach the purpose with toothed wedge belt 3 tensionings.
