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 mini-excavator air condition compressor belt tension method, belong to the air condition compressor field of power equipment technology.
Background technique
Make the field at excavator and other engineering machinery, adopt the air condition compressor compression in the refrigeration system of air-conditioning usually and drive refrigeration agent, what drive DRIVEN BY AIR CONDITIONING COMPRESSOR is the flywheel gear of motor, adopts belt to realize transmission of power.Belt needs certain pretightening force in this transmission device, and the size of belt tension and position relation directly affect the reliability of air-conditioning refrigeration system and the working life of belt.
Belt tension method commonly used at present has two kinds, and a kind of is to regulate through moving of Idle wheel, and another kind is through the rotation of compressor itself or moves and regulate.These two kinds of methods have all that requisite space is big, inconvenient operation and shortcoming such as loosening easily.
Summary of the invention
The technical problem that the present invention will solve provides a kind of apparatus structure compactness, dismounting is easy to adjust and the mini-excavator air condition compressor belt tension method of reliable performance.
In order to solve the problems of the technologies described above, technological scheme of the present invention provides a kind of mini-excavator air condition compressor belt tension method, it is characterized in that: this method is made up of following 4 steps:
Step 1: stretching wheel assembly is installed on the downside belt between engine flywheel place belt pulley and the compressor clutch belt pulley, the compressor bracket assembly is installed on the engine bearer;
Step 2: the position of regulating the compressor clutch belt pulley through the waist shaped hole substantially horizontal on the compressor bracket assembly; After making compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves remain in the same plane, the compressor bracket assembly is used the bolt pretension;
Step 3: the vee belt is installed on the belt pulley; Adjust belt through regulating bolt and lid type self-locking nut at vertical direction; With the Idle wheel pretension, guarantee the long span place of belt tension force, not having used new belt tension is 637 ± 108N; Used belt tension is 441 ± 88.2N, and bolt and lid type self-locking nut are regulated in locking;
Step 4: whether check compressor clutch belt pulley, engine flywheel place belt pulley and Idle wheel in a plane, if not in a plane, get back to step 2.
A kind of mini-excavator air condition compressor belt tension method provided by the invention through compressor bracket assembly substantially horizontal adjustment belt, makes compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves keep at grade; Adjust belt through stretching wheel assembly at vertical direction, guarantee that belt has suitable pretightening force, and then guarantee and improved the reliability of air-conditioning refrigeration system.
A kind of mini-excavator air condition compressor belt tension method provided by the invention has overcome the deficiency of existing technology, and apparatus structure is compact, and dismounting is easy to adjust, has improved the reliability of air-conditioning refrigeration system.

Embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Fig. 1 is an air condition compressor mounting unit assembly structural representation in the present embodiment, and a kind of mini-excavator air condition compressor belt tension method is made up of following 4 steps:
Step 1: stretching wheel assembly 3 is installed on the downside belt between engine flywheel place belt pulley 1 and the compressor clutch belt pulley 4, compressor bracket assembly 5 is installed on the engine bearer;
In conjunction with Fig. 3; Compressor bracket assembly 5 comprises mainboard 5-6; The first plate 5-2 is contained in mainboard 5-6 left, and the second plate 5-3 is fixed on the side of mainboard 5-6 with the 4th plate 5-5 and is 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.Have waist shaped hole 5-1 on the mainboard 5-6 right-hand part.The mainboard 5-6 of compressor bracket assembly 5 and the upper surface of engine bearer are fitted, and lock with Bolt Connection and engine bearer through the waist shaped hole 5-1 on the mainboard 5-6 right-hand part.Compressor clutch belt pulley 4 is fixed on the first plate 5-2 of compressor bracket assembly 5 through Bolt Connection.
Step 2: the position of regulating compressor clutch belt pulley 4 through the waist shaped hole 5-1 substantially horizontal on the compressor bracket assembly 5; After making compressor clutch belt grooves, dynamo belt groove and Idle wheel belt grooves remain in the same plane, compressor bracket assembly 5 is used the bolt pretension;
Step 3: the vee belt is installed on the belt pulley; Adjust belt 2 through adjusting bolt 3-1 shown in Figure 2 and lid type self-locking nut 3-2 at vertical direction; With Idle wheel 3-3 pretension; With belt tension instrumentation amount belt tension power, guarantee that not having used new belt tension is 637 ± 108N at the long span place of belt 2, used belt tension is 441 ± 88.2N.Be not inconsistent requirement if cross belt tension power, continue adjustment, after meeting the requirements, bolt 3-1 and lid shape self-locking nut 3-2 are regulated in locking;
Step 4: whether check compressor clutch belt pulley 4, engine flywheel place belt pulley 1 and Idle wheel 3-3 in a plane, if not in a plane, get back to step 2, continue adjustment, until meeting the requirements.
