DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model discloses a quick-install structure of a belt synchronous wheel assembly for a piston air compressor, comprising an aluminum frame 1, a first synchronous belt wheel 2, a second synchronous belt wheel 4 and a belt 3 or a multi-V belt.

[0022] Example 1

[0023] In the present embodiment 1, the first synchronous pulley 2 is a large synchronous pulley, the second synchronous pulley 4 is a small synchronous pulley, and the transmission is carried out by the belt 3. The belt is a preferred solution.

[0024] like Figure 1 - Figure 2 As shown, the aluminum frame 1 is integrally formed, and the inside of the shell is used to install power transmission components, such as a large synchronous pulley, a piston linkage rod, etc. The power transmission component receives the power of the motor 5 of the air compressor and outputs it to the cylinder to drive the piston to reciprocate. One side of the shell of the aluminum frame 1 is fixedly connected to the motor 5 of the air compressor, and the other side is connected to the cylinder group of the air compressor.

[0025] The aluminum frame 1 is provided with a first mounting groove 11 and a second mounting groove 12, and the size thereof is consistent with the large synchronous belt wheel and the small synchronous belt wheel. The first mounting groove 11 and the second mounting groove 12 are arranged parallel to each other to ensure that the large synchronous belt wheel and the small synchronous belt wheel are located in the same plane after assembly, and the transmission is stable.

[0026] The first synchronous pulley 2 is located outside the first mounting groove 11 of the aluminum frame 1. The center of the first synchronous pulley 2 is fixedly connected to the linkage rod of the piston located inside the first mounting groove 11, which is used to drive the connecting rod to rotate forward and reverse. The center of the second synchronous pulley 4 is installed on the output shaft of the motor 5 of the air compressor. The end of the second synchronous pulley 4 away from the motor 5 is located outside the second mounting groove 12. The belt 3 is sleeved on the outside of the first synchronous pulley 2 and the second synchronous pulley 4. The protrusions on the inner surface of the belt 3 correspond to the grooves of the first synchronous pulley 2 and the second synchronous pulley 4 one by one, synchronizing the movement of the first synchronous pulley 2 and the second synchronous pulley 4. And the speed ratio of the first synchronous pulley 2 and the second synchronous pulley 4 is 1:10.

[0027] The aluminum frame 1 and the motor 5 are fixed in the following manner: a pair of fixing ear seats 1 7 are provided on the outer side of the assembly portion 6, and a pair of fixing ear seats 2 8 are provided on the outer shell of the motor 5; the positions of the fixing ear seats 1 7 and the fixing ear seats 2 8 correspond to each other, and the long bolts 9 pass through the fixing ear seats 2 8 and the fixing ear seats 1 7 in sequence, and the ends are locked by nuts 10. In order to improve the connection firmness of the fixing ear seats 1 7 on the aluminum frame 1, a reinforcing connection section 13 is provided between the fixing ear seats 1 and the outer surface of the assembly portion 6.

[0028] The aluminum frame 1 is provided with an assembly portion 6 having a semicircular cross section, and the assembly portion 6 is located on the side of the second installation groove 12 away from the first installation groove 11, and the center axis of the semicircle center of the assembly portion 6 is coaxial with the center axis of the output shaft of the motor 5. The assembly portion 6 has the following functions: to predefine the position of the belt 3 when the second synchronous pulley 4 is not installed to prevent the belt 3 from deviating too much; to guide the second synchronous pulley 4 to be inserted toward the second installation groove 12 during installation; to protect the belt 3, the first synchronous pulley 2 and the second synchronous pulley 4 after installation; to provide protection for the staff during disassembly to prevent the staff from directly touching the belt 3, the first synchronous pulley 2 and the second synchronous pulley 4 with residual heat, or directly touching the second synchronous pulley 4 that has not stopped working in time under unexpected circumstances.

[0029] The installation process of Example 1 is as follows: During installation, first fix the first synchronous pulley 2 with the connecting rod in the aluminum frame 1, put on the belt 3, and put down the aluminum frame 1; take the motor 5, fix the second synchronous pulley 4 on the output shaft, and pre-fix the two long bolts 9 in the fixed ear seat 2 8; the staff holds the aluminum frame 1 in one hand and the motor 5 in the other hand, and moves the second synchronous pulley 4 on the motor 5 in the direction of the second installation groove 12 of the aluminum frame 1, and at the same time, the two long bolts 9 are inserted into the fixed ear seat 1 7; when the long bolts 9 are gradually inserted into the fixed ear seat 1 7 and deeper and deeper, the second synchronous pulley 4 gradually approaches the belt 3 along the semicircular assembly part 6, and is gradually inserted into the belt 3. When the end of the long bolt 9 exceeds the fixed ear seat 1 7, the installation is basically completed. At this time, the staff manually rotates the first synchronous pulley 2 so that the belt 3 is slightly rotated and adjusted to mesh with the second synchronous pulley 4. At this time, the belt 3 is tightened. The staff manually tightens the nut 10 to complete the fastening installation. When disassembling, the staff loosens the nuts 10 of the bolts on both sides, then holds the aluminum frame 1 with one hand and the motor 5 with the other hand, and pulls the two apart to separate them.

[0030] The working time of the belt 3, the first synchronous pulley 2 and the second synchronous pulley 4 of Example 1 is up to 100 hours.

[0031] Example 2

[0032] The quick-install structure of the synchronous wheel assembly of belt 3 is basically the same as that of embodiment 1, except that a poly-V belt is used instead of belt 3, which has the advantages of high transmission power, thin belt body and high flexibility.

[0033] Embodiments 1-2 of the utility model include but are not limited to being applicable to the above-mentioned air compressor, and are also applicable to other mechanical equipment with a belt 3 synchronous pulley group with a small center distance.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any mark in a claim should not be regarded as limiting the claim involved.
