Description
Technical Field
The utility model belongs to the technical field of elastic couplings, and particularly relates to an elastic rubber block coupling.
Background
The elastic rubber block coupling is used as a common coupling and consists of two half couplings which are matched with each other, an elastic element (also called an elastic rubber block) and a fixed outer sleeve. The coupling has good shock absorption, shock absorption and deviation compensation capabilities. However, the existing elastic rubber block coupling has the following disadvantages:
The service life is short: the service life of the existing elastic rubber block is short, and frequent maintenance and replacement are needed. Due to the different working environments and load conditions, the elastomeric blocks are susceptible to wear or damage, requiring periodic replacement, which increases maintenance costs and downtime.
The elasticity value lacks the ability to adjust: the elasticity value of the existing elastic rubber block is usually fixed and cannot be adjusted according to the needs of customers. However, different usage scenarios and application requirements may require different elasticity values to achieve better shock absorption and shock absorption. Because the elastic value of the existing elastic rubber block cannot be flexibly adjusted, customers often cannot meet specific requirements of the elastic rubber block, and optimization and performance of the coupler are affected.
The replacement process is inconvenient: the replacement process of the existing elastic rubber block is relatively complicated. In order to replace the elastomeric blocks, the motor needs to be moved and the entire coupling removed, which increases labor costs and replacement time.
Disclosure of utility model
In order to overcome the defects, the utility model aims to provide an elastic rubber block coupler, wherein an elastic element of the elastic rubber block coupler has the advantages of longer service life, adjustable elastic value and more convenient replacement.
The utility model is realized by the following technical scheme: the utility model provides an elastic rubber block shaft coupling, includes left half shaft coupling, right half shaft coupling, elastic rubber block and fixed overcoat, and its technical essential is: the fixed outer sleeve is sleeved on the outer side of the right half coupler; the elastic rubber block is arranged between the fixed outer sleeve and the gear teeth of the right half coupling; a supporting pipe column is axially arranged in the elastic rubber block, and threads are arranged on the inner wall of the pipe of the supporting pipe column; an annular baffle is arranged on the left side of the fixed outer sleeve; the left half coupler is connected with the fixed outer sleeve through bolts.
Further, a screw hole is formed in the left side of the fixed outer sleeve; the annular baffle is fixedly connected with the screw hole of the fixed outer sleeve through a baffle fixing bolt.
Further, the number of the elastic rubber blocks axially arranged between the fixed outer sleeve and the gear teeth of the right half coupler is two.
The utility model has the beneficial effects and characteristics that:
More convenient elastic rubber block replacement: the utility model is provided with a support pipe column in the elastic rubber block and is matched with the design of internal threads. Therefore, the elastic rubber block can be easily replaced through the long bolt, a user does not need to move a motor or detach the whole coupler, the problem that the traditional elastic rubber block replacing process is inconvenient is solved, the replacing time is greatly saved, and the labor cost is reduced.
Promote internal strength and increase of service life: the arrangement of the supporting tube column increases the internal strength of the elastic rubber block. The support pipe column is used as a structural support, and can provide better stability and strength support when the elastic rubber block is loaded. This effectively extends the useful life of the elastomeric element and reduces the need for frequent replacement of elastomeric blocks due to wear or damage.
Adjustable elastic value: the diameter of the support pipe column can be adjusted to change the elasticity value of the elastic rubber block. The larger diameter support string will result in a smaller elastic value for the elastomeric block, while the smaller diameter support string will result in a larger elastic value for the elastomeric block. The elastic value of the elastic rubber block can be flexibly adjusted according to specific application requirements and load conditions, better vibration absorption and vibration reduction effects are achieved in different couplings, and different optimization requirements are met.
