Abstract
The invention provides a tensioning method of a belt of an air-conditioning compressor of a small excavator. which is characterized by comprising the following steps of: firstly, regulating a belt according to the horizontal direction of a compressor bracket assembly to enable a compressor clutch belt slot, an engine belt slot and a tension pulley belt slot to be kept on the same horizontal plane; and then, regulating the belt in the vertical direction by a tension pulley assembly to ensure that the belt has corresponding pretightening force. According to the tensioning method of the belt of the air-conditioning compressor of the small excavator, provided by the invention, the defects of the prior art are overcome, the device structure is compact, the belt is convenient to disassemble, assemble and regulate, and the reliability of an air-conditioning refrigeration system is improved.
Description
Technical field
The present invention relates to a kind of compressor of small excavator air belt tension method, belong to air condition compressor field of power equipment technology.
Background technique
In excavator and other construction machinery production fields, usually adopt air condition compressor compression and drive refrigeration agent in the refrigeration system of air-conditioning, what drive DRIVEN BY AIR CONDITIONING COMPRESSOR is the flywheel gear of motor, adopts belt to realize transmission of power.In this transmission device, belt needs certain pretightening force, and the size of belt tension and position relationship directly affect the reliability of air-conditioning refrigeration system and the working life of belt.
At present conventional belt tension method has two kinds, and a kind of is regulated by the movement of Idle wheel, and another kind is regulated by the rotation of compressor itself or movement.These two kinds of methods have that requisite space is large, inconvenient operation and the shortcoming such as easily to loosen.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of apparatus structure is compact, dismounting is easy to adjust and the compressor of small excavator air belt tension method of reliable performance.
In order to solve the problems of the technologies described above, technological scheme of the present invention is to provide a kind of compressor of small excavator air belt tension method, it is characterized in that: the method is made up of following 4 steps:
Step 1: stretching wheel assembly is arranged on the downside belt between engine flywheel place belt pulley and compressor clutch belt pulley, compressor bracket assembly is arranged on engine bearer;
Step 2: the position being regulated compressor clutch belt pulley by the waist shaped hole substantially horizontal on compressor bracket assembly, compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves are remained on after in same plane, by compressor bracket assembly tools for bolts ' pretension;
Step 3: vee belt is installed on belt pulley, belt is adjusted at vertical direction by adjusting bolt and cap-type self-locking nut, by Idle wheel pretension, ensure belt most long span place tension force, used new belt tension is not had to be 637 ± 108N, used belt tension is 441 ± 88.2N, locking adjusting bolt and cap-type self-locking nut;
Step 4: inspection compressor clutch belt pulley, engine flywheel place belt pulley and Idle wheel whether in a plane, if not in a plane, get back to step 2.
A kind of compressor of small excavator air belt tension method provided by the invention, always horizontally adjusts belt by compressor bracket, and compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves are kept at grade; Adjust belt by stretching wheel assembly at vertical direction, ensure that belt has suitable pretightening force, and then ensure and improve the reliability of air-conditioning refrigeration system.
A kind of compressor of small excavator air belt tension method provided by the invention overcomes the deficiencies in the prior art, and apparatus structure is compact, and dismounting is easy to adjust, improves the reliability of air-conditioning refrigeration system.

Embodiment
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 1 is air condition compressor mounting unit assembly structural representation in the present embodiment, and a kind of compressor of small excavator air belt tension method is made up of following 4 steps:
Step 1: stretching wheel assembly 3 is arranged on the downside belt between engine flywheel place belt pulley 1 and compressor clutch belt pulley 4, compressor bracket assembly 5 is arranged on engine bearer;
Composition graphs 3, compressor bracket assembly 5 comprises mainboard 5-6, first plate 5-2 is contained in mainboard 5-6 left, and the second plate 5-3 and the 4th plate 5-5 are fixed on the side of mainboard 5-6 and are connected with the first plate 5-2, and the 3rd plate 5-4 is fixed on the opposite side of mainboard 5-6 and is connected with the first plate 5-2.Mainboard 5-6 right-hand part has waist shaped hole 5-1.The mainboard 5-6 of compressor bracket assembly 5 and the upper surface of engine bearer are fitted, and are locked by the waist shaped hole 5-1 Bolt Connection on mainboard 5-6 right-hand part and engine bearer.Compressor clutch belt pulley 4 is fixed on the first plate 5-2 of compressor bracket assembly 5 by Bolt Connection.
Step 2: the position being regulated compressor clutch belt pulley 4 by the waist shaped hole 5-1 substantially horizontal on compressor bracket assembly 5, compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves are remained on after in same plane, by compressor bracket assembly 5 tools for bolts ' pretension;
Step 3: vee belt is installed on belt pulley, by the adjusting bolt 3-1 shown in Fig. 2 and cap-type self-locking nut 3-2 at vertical direction adjustment belt 2, by Idle wheel 3-3 pretension, in the most long span place belt tension measurement amount belt tension power of belt 2, guarantee does not have used new belt tension to be 637 ± 108N, and used belt tension is 441 ± 88.2N.If cross belt tension power not to be inconsistent requirement, continue adjustment, until after meeting the requirements, locking adjusting bolt 3-1 and lid shape self-locking nut 3-2;
Step 4: inspection compressor clutch belt pulley 4, engine flywheel place belt pulley 1 and Idle wheel 3-3, whether in a plane, if not in a plane, get back to step 2, continue adjustment, until meet the requirements.
