Abstract
The utility model discloses a kind of ball blast axis system for sand-blasting machine, it includes the ball blast main shaft and main shaft bearing pedestal to cooperate, the outside of the main shaft bearing pedestal is provided with compressed air inlet and the main shaft water collar for radiating, has the water inlet and delivery port being oppositely arranged on the main shaft water collar；The main shaft bearing pedestal is provided with the bearing gland connected with the compressed air inlet with going out between shaft end for ball blast main shaft, the border that the ball blast main shaft goes out shaft end is additionally provided with the mechanical dust-proof labyrinth gland being engaged with the bearing gland, labyrinth cavity is formed between the dust-proof labyrinth gland of the machinery and bearing gland, the labyrinth cavity introduces compressed air by the compressed air inlet on bearing seat and forms positive air pressure.The utility model deft design, can effectively reduce ball blast main shaft caused heat in operation, at the same can be fabulous prevent the entrance of dust, as long as periodically adding lubricating grease, can greatly improve the service life of existing ball blast main shaft.
Description
Technical field
It the utility model is related to the impeller head of sand-blasting machine, more particularly to a kind of ball blast axis system for sand-blasting machine.
Background technology
The ball blast main shaft of sand-blasting machine when in use, because spindle nose is equipped with ball blast disk so that spindle nose bears very big
Radial load, simultaneously because ball blast spindle nose is located at sandblasting storehouse, thus ball blast and dust are all very big, most ball blasts
Main shaft bearing damage is all to be damaged by the dust-proof reinforced seal of its end and caused, and because sand grains enters main shaft bearing cavity, and is made
Into bearing premature breakdown；Another source of damage is due to that bearing heating is serious (it is larger to bear radial load), but radiating effect
It is bad, and cause the constant temperature of bearing to be in 80 to 110 ° of states of high temperature, such as now slightly lubricating bad or dust enters, axle
Holding to be damaged rapidly, and then causes stop production to overhaul.Existing ball blast main shaft service life between 2 to 3 months, it is short
With regard to 1 week or so, very big influence is brought to normal continuous production.
Utility model content
The purpose of this utility model is to be directed to above-mentioned deficiency of the prior art, there is provided a kind of ball blast for sand-blasting machine
Axis system, it is common in the art because sand grains enters main shaft bearing cavity to solve, and bearing premature breakdown is caused, and
The problem of bearing heating is serious, but radiating effect is bad.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of ball blast axis system for sand-blasting machine, it includes the ball blast main shaft and main shaft bearing pedestal to cooperate,
The outside of the main shaft bearing pedestal is provided with compressed air inlet and the main shaft water collar for radiating, has on the main shaft water collar
There are the water inlet and delivery port being oppositely arranged；The main shaft bearing pedestal and ball blast main shaft go out between shaft end to be provided with and the pressure
The bearing gland of contracting air intlet connection, the border that the ball blast main shaft goes out shaft end is additionally provided with the machine being engaged with the bearing gland
The dust-proof labyrinth gland of tool, labyrinth cavity is formed between the dust-proof labyrinth gland of the machinery and bearing gland, the labyrinth cavity passes through
Compressed air inlet on bearing seat introduces compressed air and forms positive air pressure, to play dust-proof and air-cooled effect.
The ball blast axis system deft design that the utility model is proposed, it can effectively reduce ball blast main shaft and produce in operation
Raw heat, while fabulous the entrance of dust can be prevented, as long as periodically adding lubricating grease, it can greatly improve existing ball blast
The service life of main shaft, and then production efficiency can be effectively improved, reduce cost, thus there is higher popularizing value.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- ball blast main shafts, 2- main shaft bearing pedestals, 21- compressed air inlets, 3- main shaft water collars, 31- water inlets
Mouthful, 32- delivery ports, 4- bearing glands, the dust-proof labyrinth gland of 5- machineries.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model discloses a kind of ball blast axis system for sand-blasting machine, it includes cooperating
Ball blast main shaft 1 and main shaft bearing pedestal 2, the outside of the main shaft bearing pedestal 2 is provided with compressed air inlet 21 and for dissipating
The main shaft water collar 3 of heat, there is the water inlet 31 and delivery port 32 being oppositely arranged on the main shaft water collar 3；The main shaft bearing
Pedestal 2 is provided with the bearing gland 4 connected with the compressed air inlet 21, so-called ball blast with going out between shaft end for ball blast main shaft 1
Main shaft goes out the shaft end i.e. outer end of ball blast main shaft；The border that the ball blast main shaft 1 goes out shaft end is additionally provided with to match with the bearing gland 4
The mechanical dust-proof labyrinth gland 5 of conjunction, labyrinth cavity, the labyrinth are formed between the dust-proof labyrinth gland 5 of the machinery and bearing gland 4
Cavity is introduced into compressed air by the compressed air inlet 21 on bearing seat 2 and forms positive air pressure in the labyrinth cavity, makes
Obtain the dust outside ball blast main shaft 1 and cannot be introduced into labyrinth cavity, while air-cooled effect can be also played to ball blast main shaft 1.
It is above illustrative to description of the present utility model and application, is not wishing to the scope of the utility model being limited in
In above-described embodiment；In the case where not departing from the scope of the utility model and spirit, embodiments disclosed herein can be entered
The other deformations of row and change.
