Abstract
The utility model provides a combined pulley, it includes a bearing piece and two weight stacks, the bearing piece presss from both sides with one heart to be established between two weight stacks, and the external diameter of bearing piece is less than the external diameter of weight stack. Compared with the prior art, the utility model discloses following beneficial effect has: by the working of plastics as counterweight and the metalwork pulley that the combination formed as load bearing member, the use of having practiced thrift metal material, the cost is reduced, it is not durable to have solved the pulley in addition, problem that the bearing capacity is low.
Description
Technical field
This utility model relates to a kind of combination type pulley, belongs to technical field of engineering machinery.
Background technology
The pulley of prior art, is typically all by homogenous material one molding, material or be metal, or is plastics, but, whether metal or plastics, all it is respectively arranged with drawback, such as the pulley lighter weight that plastics are made, but is not durable, bearing capacity is low；And metal pulley is durable, bearing capacity is strong, but relatively costly.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of combination type pulley.
This utility model is achieved through the following technical solutions:
A kind of combination type pulley, it includes a load-bearing piece and two weight stacks, and described load-bearing piece is folded between two weight stacks with one heart, and the external diameter of load-bearing piece is less than the external diameter of weight stack；Or
One skeleton and a reinforcing sleeve, described reinforcing sleeve is nested in outside skeleton, and the thickness of described skeleton is more than the thickness of reinforcing sleeve.
Preferably, the ratio of the thickness of described load-bearing piece and weight stack is 4:3.
Preferably, the material of described load-bearing piece is metal, and the material of described weight stack is plastics.
Preferably, the inside of described load-bearing piece is provided with the dead eye matched with bearing outline.
Preferably, the material of described reinforcing sleeve is metal, and the material of described skeleton is plastics.
Preferably, the inside of described skeleton is provided with the dead eye matched with bearing outline..
Compared with prior art, this utility model has following beneficial effect:
1, the pulley combined as supporting part as counterweight and metalwork by working of plastics, has saved the use of metal material, reduces cost, and solves pulley and be not durable, the problem that bearing capacity is low；
2, the pulley combined as reinforcing sleeve as skeleton and metalwork by working of plastics, has saved the use of metal material, reduces cost, and solves pulley and be not durable, the problem that bearing capacity is low.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in detail.Following example will assist in those skilled in the art and are further appreciated by this utility model, but do not limit this utility model in any form.It should be pointed out that, to those skilled in the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement.These broadly fall into protection domain of the present utility model.
Embodiment 1
The present embodiment provides a kind of combination type pulley, and as depicted in figs. 1 and 2, including a load-bearing piece 1 and two weight stacks 2, load-bearing piece 1 is folded between two weight stacks 2 its structure with one heart, and the external diameter of load-bearing piece 1 is less than the external diameter of weight stack 2.
Preferably, the ratio of the thickness of described load-bearing piece 1 and weight stack 2 is 4:3.
Preferably, the material of described load-bearing piece 1 is metal, and the material of described weight stack 2 is plastics.
Preferably, the inside of described load-bearing piece 1 is provided with the dead eye 11 matched with bearing outline.
Embodiment 2
The present embodiment provides a kind of combination type pulley, and as shown in Figure 3 and Figure 4, including a skeleton 3 and a reinforcing sleeve 4, reinforcing sleeve 4 is nested in outside skeleton 3 its structure, and the thickness of skeleton 3 is more than the thickness of reinforcing sleeve 4.
Preferably, the material of reinforcing sleeve 4 is metal, and the material of skeleton 3 is plastics.
Preferably, the inside of skeleton 3 is provided with the dead eye 31 matched with bearing outline.
Compared with prior art, this utility model has following beneficial effect:
1, the pulley combined as supporting part as counterweight and metalwork by working of plastics, has saved the use of metal material, reduces cost, and solves pulley and be not durable, the problem that bearing capacity is low；
2, the pulley combined as reinforcing sleeve as skeleton and metalwork by working of plastics, has saved the use of metal material, reduces cost, and solves pulley and be not durable, the problem that bearing capacity is low.
Above specific embodiment of the utility model is described.It is to be appreciated that this utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various deformation or amendment within the scope of the claims, and this has no effect on flesh and blood of the present utility model.
