Abstract
The utility model discloses a crushing tooth roller connected through expansion sleeves. The crushing tooth roller comprises a tooth roller (6), wherein toothed bars (1) are arranged on the outer surface of the tooth roller (6); the tooth roller (6) adopts a hollow structure; connecting holes (4) are formed in the two ends of the tooth roller (6); a core shaft (3) is mounted inside the connecting holes (4) in a sleeving manner; expansion sleeve steps (5) are arranged at the outer ends of the connecting holes (4); expansion sleeves (7) are arranged inside the expansion sleeve steps (5) and sleeve the core shaft (7). According to the utility model, the crushing tooth roller has the following benefits: the crushing tooth roller has the advantages of high connecting strength, convenience for dismounting and mounting, great crushing force and long service life.
Description
Technical field
The utility model relates to disintegrating machine attaching parts, the crushing toothed roller that particularly a kind of ringfeder connects.
Background technology
Crushing toothed roller, mainly in order on disintegrating machine, need to be connected with mandrel during installation, and discaling roll inside is hollow structure, discaling roll of the prior art and mandrel bindiny mechanism are that core sleeve is in discaling roll, and by key, fix, but due to discaling roll at work, bear very large impulsive force, key is easy to wear, can not meet discaling roll bonding strength, and connect by key, during assembling, working strength is larger, during maintenance, dismounting is inconvenient.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, the crushing toothed roller that provides a kind of easy accessibility, the broken great efforts ringfeder high with bonding strength to be connected.
The purpose of this utility model is achieved through the following technical solutions: the crushing toothed roller that a kind of ringfeder connects, it comprises discaling roll, on discaling roll outer surface, be provided with tooth bar, discaling roll inside is hollow structure, two terminations of discaling roll offer connecting hole, are set with mandrel in connecting hole, and connecting hole external end head is provided with ringfeder step, in ringfeder step, be provided with ringfeder, ringfeder is enclosed within on mandrel.
On described ringfeder outer face, offered a screwed hole, the screw coordinating with screwed hole was installed in screwed hole.
Described screw is hexagon socket countersunk flat cap head screw.
Described tooth bar is many groups, and the profile of tooth of tooth bar is the ox horn profile of tooth that leans forward.
Described multiple sets of teeth bar is parallel structure or the interlaced helical distributed architecture of being uniformly distributed.
The internal diameter of described ringfeder step is greater than connecting hole internal diameter
The utlity model has following advantage: crushing toothed roller of the present utility model adopts ringfeder bindiny mechanism, bonding strength and the rigidity of discaling roll and mandrel are significantly improved, and easy accessibility, tooth bar adopts the ox horn profile of tooth that leans forward, increased the broken dynamics of crushing toothed roller, and tooth bar is not easy to wear, thus it have advantages of that bonding strength is high, easy accessibility, broken great efforts and long service life.
Accompanying drawing explanation
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-tooth bar, 2-screw, 3-mandrel, 4-connecting hole, 5-ringfeder step, 6-discaling roll, 7-ringfeder.
the specific embodiment
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 depicted in figs. 1 and 2, the crushing toothed roller that a kind of ringfeder connects, it comprises discaling roll 6, on discaling roll 6 outer surfaces, be provided with tooth bar 1, tooth bar 1 is many groups, the profile of tooth of tooth bar 1 is the ox horn profile of tooth that leans forward, multiple sets of teeth bar 1 is parallel structure or the interlaced helical distributed architecture of being uniformly distributed, preferential employing interlaced helical shape distributed architecture, discaling roll 6 inside are hollow structure, two terminations of discaling roll 6 offer connecting hole 4, in connecting hole 4, be set with mandrel 3, connecting hole 4 external end heads are provided with ringfeder step 5, the internal diameter of ringfeder step 5 is greater than connecting hole 4 internal diameters, in ringfeder step 5, be provided with ringfeder 7, ringfeder 7 is enclosed within on mandrel 3, on ringfeder 7 outer faces, offered a screwed hole, the screw 2 coordinating with screwed hole is installed in screwed hole, preferential screw 2 adopts hexagon socket countersunk flat cap head screw.
The course of work of the present utility model is as follows: discaling roll 6 is arranged on mandrel 3, and by adjustment screw 2, discaling roll 6 and mandrel 3 is held tightly, it cannot be relatively rotated, then drive motors drives mandrel 3 to rotate, and mandrel 3 drives discaling roll 6 to rotate, and discaling roll 6 adopts the cattle horn shape tooth bar 1 that leans forward, making its tooth bar 1 and broken object is that point contacts, cause broken dynamics first mate to increase, improved operating efficiency, during equipment dismounting, only need slack adjuster 2 just can carry out dismounting to discaling roll 6, thereby dismounting is very convenient.
