Description

Technical Field

[0001] This utility model relates to the technical field of diaphragm compressor components, specifically to a multi-purpose diaphragm compressor crankshaft extender. Background Technology

[0002] A diaphragm compressor mainly consists of a motor, crankcase, crankshaft connecting rod mechanism, cylinder block components, oil and gas pipelines, electronic control system, and accessories. The motor's torque needs to be transmitted to the crankshaft. Currently, the transmission system connects the crankshaft extending from the crankcase to the flywheel or pulley via a coupling or belt, which in turn connects to the motor's output shaft. Depending on the customer's required medium flow rate, the calculated cylinder head size varies. Direct-drive diaphragm compressors use a coupling to make the motor and flywheel coaxial, avoiding interference between the transmission components and the cylinder head. Belt-driven diaphragm compressors, due to the excessively large cylinder head component size and the fixed length of the crankshaft extending from the crankcase, cause interference between the cylinder head and the flywheel. Belt-driven diaphragm compressors connect the crankshaft directly to the pulley via a key, with the motor driving the pulley via the belt. However, if the cylinder head size exceeds the crankcase width by a certain dimension, it can cause interference between the belt and the cylinder head. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-purpose diaphragm compressor crankshaft extender to overcome the aforementioned defects in the prior art.

[0004] A multi-purpose diaphragm compressor crankshaft extender includes a first flange, an extender body, and a friction-reducing pad. The first flange is disposed on the crankshaft body of the crankcase. The end of the extender body is provided with a second flange. The friction-reducing pad is disposed between the first flange and the second flange. The first flange, the second flange, and the friction-reducing pad are connected to each other. A first pulley is mounted on the extender body. The first pulley is connected to a second pulley on a motor via a drive belt.

[0005] Preferably, the friction-reducing pads are provided in a plurality of units.

[0006] Preferably, the flange is connected to the crankshaft body by a number of fastening bolts.

[0007] Preferably, the first flange, the second flange, and the friction-reducing pad are connected by limiting bolts.

[0008] Preferably, the end of the extender body is provided with a bearing seat.

[0009] Preferably, the bearing housing is connected to the extender body by screws.

[0010] The beneficial effects achieved by this utility model are as follows:

[0011] This application sets multiple anti-friction pads between flange one and flange two. Flange one, flange two and anti-friction pads are connected by limit bolts, which facilitates the assembly and disassembly of the three. Designers can adjust the connection length by changing the number of anti-friction pads according to design requirements to adapt to equipment of different specifications, thereby avoiding interference.

[0017] like Figure 1-3 As shown, this utility model provides a multi-purpose diaphragm compressor crankshaft extender, including a flange 2, an extender body 3, and a friction-reducing pad 4. The flange 2 is disposed on the crankshaft body 11 of the crankcase 1. The flange 2 and the crankshaft body 11 are connected by several fastening bolts, which facilitates the disassembly and assembly of the flange 2.

[0018] In addition, the end of the extension body 3 is provided with flange 2 31, and several anti-friction pads 4 are provided and located between flange 1 2 and flange 2 31. Flange 1 2, flange 2 31 and anti-friction pads 4 are connected by limit bolts, so as to facilitate the assembly and disassembly of the three. The axial distance can be adjusted by increasing or decreasing the number of anti-friction pads 4 to adapt to different specifications of equipment.

[0019] In addition, a pulley 5 is installed on the extender body 3. The pulley 5 is connected to the pulley 81 on the motor 8 via a drive belt 7. A bearing seat 6 is provided at the end of the extender body 3. The bearing seat 6 is connected to the extender body 3 by screws, which can prevent dust from entering and also prevent the pulley 5 from flying off during high-speed operation.

[0020] In summary, this application provides multiple anti-friction pads 4 between flange 1 2 and flange 2 31. Flange 1 2, flange 2 31 and anti-friction pads 4 are connected by limit bolts, which facilitates the assembly and disassembly of the three components.
