Abstract
The utility model relates to a locking structure of a synchronous pulley. The locking structure comprises a synchronous pulley inner taper sleeve, the synchronous pulley and connecting bolts, wherein a protruded loop is arranged at one end of the synchronous pulley inner taper sleeve, an inner hole is formed in the middle portion of the synchronous pulley, the shape and the size of the loop is adaptive to those of the inner hole so as to sleeve the inner hole on the loop, and the synchronous pulley inner taper sleeve is connected with the synchronous pulley through the connection bolts. The locking structure is stable, reliable, convenient to install and detach, and capable of effectively overcoming defects of existing synchronous pulley locking structures.
Description
Technical field
The utility model relates to a kind of locking mechanism of synchronous pulley.
Background technique
Shedding device of weaving machine be mainly by loom excess power cut apart transmission as power resources, its transmission type for band transmission, be to drive the synchronous pulley on shedding motion to carry out power transmission by the synchronous pulley on loom by Timing Belt.Be now locking hood type locking for the general Placement of the synchronous pulley on loom opening and shedding motion input shaft, its synchronous pulley locking mechanism cracks for attachment hole is installed, make synchronous pulley and shaft locking by a lock bolt, this kind of locking mode exists that locking is not firm, synchronous pulley is bad with the coaxality of installation coupling shaft, synchronous pulley teeth surface jitter is larger, Timing Belt is beated while moving, and great Yi causes the drawbacks such as Timing Belt damage.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of locking mechanism of locking firm synchronous pulley.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of locking mechanism of synchronous pulley, comprise belt wheel inner conical drogue, synchronous pulley and connecting bolt, one end of described belt wheel inner conical drogue is provided with protruding ring set, the intermediate portion of described synchronous pulley is provided with an endoporus, shape and the size of the shape of described ring set and size and described endoporus all match, described inner hole sleeve is contained on described ring set, and described belt wheel inner conical drogue is connected with described synchronous pulley by described connecting bolt.
The beneficial effects of the utility model are: the utility model is reliable and stable, and easy installation and removal can effectively overcome the shortcoming of original synchronous pulley locking mechanism.
On the basis of technique scheme, the utility model can also do following improvement.
Further, on a sidewall of described belt wheel inner conical drogue, have a groove.
Accompanying drawing explanation
Fig. 1 is the structural representation of the locking mechanism of the utility model synchronous pulley;
In accompanying drawing, the list of parts of each label representative is as follows:
1, belt wheel inner conical drogue, 2, synchronous pulley, 3, connecting bolt, 4, ring set, 5, endoporus, 6, groove.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of locking mechanism of synchronous pulley, as shown in Figure 1, comprise belt wheel inner conical drogue 1, synchronous pulley 2 and connecting bolt 3, one end of described belt wheel inner conical drogue 1 is provided with protruding ring set 4, the intermediate portion of described synchronous pulley 2 is provided with an endoporus 5, shape and the size of the shape of described ring set 4 and size and described endoporus 5 all match, and described endoporus 5 is sleeved on described ring set 4, and described belt wheel inner conical drogue 1 is connected with described synchronous pulley 2 by described connecting bolt 3.
On one sidewall of described belt wheel inner conical drogue 1, have a groove 6.
Working principle of the present utility model is as follows:
Belt wheel inner conical drogue 1 is sleeved on axle, the endoporus 5 of synchronous pulley 2 is sleeved on the ring set 4 of belt wheel inner conical drogue 1, when connecting bolt 3 rotational lock, synchronous pulley 2 and belt wheel inner conical drogue 1 are moved axially relatively and decreased distance, cause belt wheel inner conical drogue 1 and synchronous pulley 2 to form taper fit, belt wheel inner conical drogue 1 circumferentially shrinks and clamp shaft, thereby realizes the locking of synchronous pulley 2 and coupling shaft.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. the locking mechanism of a synchronous pulley, it is characterized in that: comprise belt wheel inner conical drogue, synchronous pulley and connecting bolt, one end of described belt wheel inner conical drogue is provided with protruding ring set, the intermediate portion of described synchronous pulley is provided with an endoporus, shape and the size of the shape of described ring set and size and described endoporus all match, described inner hole sleeve is contained on described ring set, and described belt wheel inner conical drogue is connected with described synchronous pulley by described connecting bolt.
2. the locking mechanism of synchronous pulley according to claim 1, is characterized in that: on a sidewall of described belt wheel inner conical drogue, have a groove.
