Abstract

The utility model belongs to the ordinary measures for generating and maintaining the effective operations of machines or equipment, which relates to a shaft sleeve protection device of casting machine crystallizer vibration device; the utility model is to conduct improvement to a pinhole structure, the shaft sleeve protection device is arranged at a pinhole; the device is composed of a shaft sleeve, the shaft sleeve inner part is provided with an oil groove to be packed with lubrication oil, the shaft sleeve is interference matched with the pinhole, the shaft sleeve outer part is provided with a location part to be located with a location hole left on the pinhole. The utility model has the advantages that the shaft sleeve is interference matched with the pinhole, which can prevent the shaft sleeve from sliding in axial direction and radial direction during the vibration; in addition, the shaft sleeve protection device is wear-proof with small wear and convenient replacement; the utility model can reduce the maintenance time and expenses, as well as greatly decrease the maintenance cost.

Description

A kind of axle sleeve protective gear

Technical field

The utility model belongs to for producing and keep the general measure of effective operation of machine or equipment, relates to a kind of axle sleeve protective gear of conticaster crystallizer shake unit.

Background technique

Casting machine is when carrying out strand, and conticaster crystallizer will ceaselessly vibrate, so that strand is evenly moulded adobe blocks.Existing conticaster crystallizer shake unit as shown in Figure 1 and Figure 2, vibrating table 1 is connected by bearing pin 3, bearing 4, axle head baffle plate 5 with shaker arm 2, forms shake unit.Because it is gapped between axle head baffle plate 5 and the bearing pin 3, when the conticaster crystallizer shake unit vibrates, produce slide relative between bearing pin 3 and the pin-and-hole, the hardness ratio bearing pin of pin-and-hole is low, and vibration frequency is very high, general per minute between 200～300 times, long-term vibration, the pin-and-hole of vibrating table 1 will be worn.After wearing and tearing reached certain interval, shake unit produced in vibration and rocks, and the vibration precision of shake unit does not reach usage requirement.This produces certain influence to slab quality, can't produce normally when serious, must change vibrating table 1, causes the tremendous economic loss to the user.

Summary of the invention

The purpose of this utility model is that the pin-and-hole structure is improved, and at the pin-and-hole place of vibrating table 1 the axle sleeve protective gear is installed, and reduces the wearing and tearing of pin-and-hole.

The utility model is achieved in that at the pin-and-hole place of vibrating table 1 installs the axle sleeve protective gear, and this device is made of axle sleeve, key or screw, oil groove.The pin-and-hole of axle sleeve and vibrating table 1 is an interference fit, and locatees with key or screw, and there is oil groove axle sleeve inside, can the packing lubrication grease.

The utility model compared with prior art has following advantage:

1. the material of axle sleeve can be selected high-abrasive material for use, and heat-treats, and increases surface hardness;

2. in the axle sleeve lubricant grease is arranged, can reduce the friction between bearing pin and the axle sleeve, reduce wear;

3. can change after the axle sleeve wearing and tearing, needn't change whole vibrating table 1, reduce engineering time and expense, significantly reduce maintenance cost.

Effect of the present utility model is that the pin-and-hole of axle sleeve and vibrating table 1 is an interference fit, can prevent at the vibration Intermediate shaft sleeve axially and radially slide; And the axle sleeve protective gear is wear-resisting, and it is little to wear and tear, and it is convenient to change.Can reduce engineering time and expense, significantly reduce maintenance cost.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model:

As seen from Figure 3: axle sleeve 6 is installed at the pin-and-hole place at vibrating table 1, and axle sleeve 6 is an interference fit with the pin-and-hole of vibrating table 1.

By Fig. 4～Fig. 6 as can be seen: there is oil groove 8 axle sleeve 6 inside, can the packing lubrication grease, and the keyway location of staying on the axle sleeve 6 external belt keys 7, key 7 and pin-and-hole.

By Fig. 7, Fig. 8 as can be seen: have screw 9 on the axle sleeve 6, the screw hole location of staying on screw 9 and the pin-and-hole.。

The material of axle sleeve 6 can be selected high-abrasive material for use, and heat-treats, and increases surface hardness.
