Abstract
The utility model discloses a symmetric key joint tooth roller. The symmetric key joint tooth roller comprises a tooth roller body (5) which is hollow, a plurality of groups of racks are arranged on the outer surface of the tooth roller body (5), the racks distributed on the same circumference form a group, each group of racks consist of circular arc-shaped racks (1) and regular trapezoidal racks (2), the regular trapezoidal rack (2) is arranged between every two adjacent circular arc-shaped racks (1), the groups of racks are spirally distributed on the tooth roller body (5) at intervals, connection holes (4) are formed in the two ends of the tooth roller body (5), and a symmetric key slot (3) is formed in the horizontal inner wall of each connection hole (4). The symmetric key joint tooth roller has the benefits and advantages of being good in crushing effect, high in crushing efficiency, simple in structure and convenient in mounting.
Description
Technical field
The utility model relates to the connected mode of disintegrating machine parts, the discaling roll that particularly a kind of symmetrical key connects.
Background technology
Discaling roll is mainly used in disintegrating apparatus, need to be when mounted connected with driving shaft, due to discaling roll in the course of the work, suffered impulsive force and load are larger, so the bonding strength of discaling roll is had relatively high expectations, traditional connected mode is that singly-bound connects at present, this kind of connected mode, bonding strength can not meet the large burden requirement of discaling roll, causes the impulsive force of discaling roll to reduce, and affects crushing efficiency and the effect of disintegrating machine.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, the discaling roll that provides a kind of symmetrical key simple in structure, that simple installation is high with bonding strength to be connected.
The purpose of this utility model is achieved through the following technical solutions: the discaling roll that a kind of symmetrical key connects, it comprises discaling roll, discaling roll inner hollow, on discaling roll outer surface, be provided with multiple sets of teeth bar, the tooth bar being distributed on same circumference is same group of tooth bar, and every group of tooth bar is made up of arc-shaped rack and trapezoid tooth bar, and be provided with a trapezoid tooth bar between adjacent two arc-shaped racks, the multiple sets of teeth bar of telling is distributed on discaling roll twist, two terminations of discaling roll offer connecting hole, offer a symmetrical key in the horizontal interior walls of connecting hole.
Described symmetrical key runs through whole connecting hole.
Described arc-shaped rack size is greater than the size of trapezoid tooth bar.
The utlity model has following advantage: discaling roll of the present utility model, discaling roll tooth bar adopts many group spiral spacer to distribute, not only can increase crushing efficiency, and trapezoid tooth bar can also carry out second-time breakage to material, increase crushing effect, by symmetrical key syndeton, without the bonding strength and the rigidity that have increased discaling roll and driving shaft, also meet the instructions for use of large load, and simple in structure, easy for installation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is that schematic diagram is looked on a left side of the present utility model
In figure, 1-arc-shaped rack, 2-trapezoid tooth bar, 3-symmetrical key, 4-connecting hole, 5-discaling roll.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, the discaling roll that a kind of symmetrical key connects, it comprises discaling roll 5, discaling roll 5 inner hollow, on discaling roll 5 outer surfaces, be provided with multiple sets of teeth bar, the tooth bar being distributed on same circumference is same group of tooth bar, and every group of tooth bar is made up of arc-shaped rack 1 and trapezoid tooth bar 2, and be provided with a trapezoid tooth bar 2 between adjacent two arc-shaped racks 1, arc-shaped rack 1 size is greater than the size of trapezoid tooth bar 2, in the time of fragmentation, can prevent that bulky grain is stuck between arc-shaped rack 1, and trapezoid tooth bar 2 can carry out second-time breakage to material, strengthen the breaking strength of discaling roll, the multiple sets of teeth bar of telling is distributed on discaling roll 5 twist, spaced apart by spirality, further reduce the gap between tooth bar, two terminations of discaling roll 5 offer connecting hole 4, in the horizontal interior walls of connecting hole 4, offer a symmetrical key 3, described symmetrical key 3 runs through whole connecting hole 4, adopt two keyway syndetons, not only increase bonding strength and the rigidity of discaling roll 5 with driving shaft, also meet the real requirement of large load, and simple in structure, easy for installation.
Claims (3)
