The withdrawal sleeve is arranged on the spindle head through a flat key and a connection transmission part. The withdrawal sleeve is simple in structure, easy to manufacture, convenient to install and maintain, long in service life, low in manufacturing cost and suitable for disassembly of the connection transmission parts when various devices are maintained, especially disassembly of the connection transmission parts of motors with large-and-middle-sized shaft diameters, rollers, pulping machine, sorting devices and the like.

Description

A kind of withdrawal sleeve

Technical field

The utility model relates to a kind of withdrawal sleeve of equipment joint transmission part dismounting.

Background technique

Traditional equipment joint transmission part design and installation employing transferring power or moment of torsion, but have following deficiency: one, the fit tolerance of spindle nose and joint transmission part requires tighter, and gap is too small, and inconvenience is installed, and needs to spend larger manpower etc.; Excesssive gap, spindle nose and pore volume are easy to wear, affect transmission.They are two years old, use after the long period, when m of e need be dismantled joint transmission part, need employ the dismounting of the extracting tool such as La Ma or jack, if coordinate tighter, especially the reason such as corrosion interlock when long, by being still difficult to dismounting after heating, immersion oil, even adopt failure mode to dismantle, effort when flower, and cause waste, affect work efficiency.

Model utility content

The purpose of this utility model is to provide a kind of simple in structure, installation and maintenance convenience, low cost of manufacture, withdrawal sleeve that work efficiency is high.

The technical solution of the utility model is achieved in that he comprises equipment, spindle nose, and withdrawal sleeve is arranged on spindle nose by bolt by flat key and joint transmission part.

The utility model has the advantages that: 1, simple in structure, be easy to manufacture, installation and maintenance are convenient; 2, be convenient to dismounting, work efficiency is high; Shelf life is long, low cost of manufacture.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model

Embodiment

As shown in Figure 1, comprise equipment 1, spindle nose 2, withdrawal sleeve 5 is arranged on spindle nose 2 by bolt 3 by flat key 4 and joint transmission part 6.

Withdrawal sleeve 5 selects carbon steel material to make, and withdrawal sleeve 5 endoporus coordinate connection with the spindle nose 2 of equipment 1, and endoporus is processed with the keyway corresponding with spindle nose 2; Cylindrical is designed to cone, consistent with joint transmission part 6 hole tapers; End face flange part is designed with equally distributed through hole, is designed with equally distributed harness cord simultaneously, and through hole and harness cord center circle size are consistent with the thread center's circle size on joint transmission part 6 end faces; After withdrawal sleeve 5 processes, process a flexible narrow groove at axial direction again, be convenient to withdrawal sleeve 5 and coordinate installation with joint transmission part 6; Joint transmission part 6 end faces are processed with concave station, are convenient to install withdrawal sleeve 5, bolt 3 and relevant device component.

Before installation, withdrawal sleeve 5 and joint transmission part 6 process according to transferring power and loading condition design.When installation, first withdrawal sleeve 5, joint transmission part 6 are connected to (temporarily not exclusively fastening) by bolt 3, corresponding flat key 4 is installed in the keyway of spindle nose 2.Then withdrawal sleeve 5, joint transmission part 6 are coordinated to installation with spindle nose 2, because of withdrawal sleeve 5 completely not fastening with the connecting bolt 3 of joint transmission part 6, there is a little loosening leeway, and withdrawal sleeve 5 is processed with the narrow groove of axial stretching, utilize pressure or hammering method to make withdrawal sleeve 5 constantly push spindle nose 2, until spindle nose 2, withdrawal sleeve 5, joint transmission part 6 fit like a glove and work good.Finally that connecting bolt 3 is completely fastening, work the transmitting torque effect that connects.In the time that equipment needs maintaining, first bolt 3 is removed, and the bolt of the corresponding size of harness cord of withdrawal sleeve 5 end face flanges is screwed into, along with bolt is constantly screwed into, bolt constantly pushes and contacts with joint transmission part 6 simultaneously, 5 of withdrawal sleeves relatively constantly exit, and owing to being that cone coordinates between withdrawal sleeve 5, joint transmission part 6, are easy to so just can dismantle and exit withdrawal sleeve 5, joint transmission part 6.

Claims (1)

1. a withdrawal sleeve, comprise equipment (1), spindle nose (2), it is characterized in that: withdrawal sleeve (5) is arranged on spindle nose (2) by bolt (3) by flat key (4) and joint transmission part (6).
