A kind of chisel holder system of food processor
Technical field
The utility model relates to a kind of chisel holder system of food processor, and the particularly chisel holder system of mixer or juice extractor belongs to the renovation technique of food processor chisel holder system.
Background technology
The chisel holder system of food processor such as the mixer on the market, juice extractor generally adopts oiliness bearing or ball bearing to support the structure of cutter shaft.Oiliness bearing is with low cost, but fluctuation of service, noise is very big after use a period of time, wearing and tearing easily, and service life is shorter.And use ball bearing, an independent ball bearing rocks greatly, influence is stirred or the effect of squeezing the juice, so need two ball bearings to use together usually, and uses two ball bearings, cost can be very high and during work noise very big.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of stable, long service life, the chisel holder system of nonabradable food processor.
In order to realize above-mentioned technical purpose, the utility model comprises following technical characterictic: a kind of chisel holder system of food processor, comprise blade, cutter shaft, bearing, tool rest and bearing insert, described blade is located on the cutter shaft, cutter shaft supports by bearing, bearing is bearing on the tool rest by the bearing insert that is arranged on its outside, described bearing comprises oiliness bearing and ball bearing, described oiliness bearing inboard is a loop wire groove around cutter shaft, and described ball bearing is located in the groove of oiliness bearing inboard.
The height of described ball bearing is less than the height of oiliness bearing, and described oiliness bearing embeds in the ball bearing.
Described oiliness bearing is one or more.
Described ball bearing is one or more.
The lower end of described cutter shaft is provided with clutch.
Be provided with sealing ring between described ball bearing and the bearing insert.
Described ball bearing upper end is provided with first packing ring.
Tool rest is plastic cement or five metals material tool rest.
Described oiliness bearing lower end is provided with second packing ring.
Described bearing insert upper end is provided with the 3rd packing ring.
The utility model compared with prior art, because being provided with ball bearing in oiliness bearing replaces traditional oiliness bearing structure, the form that promptly adopts sliding friction and rolling friction to mix, therefore it is short service life that it can overcome present oiliness bearing, easy to wear, the shortcoming of fluctuation of service, and the cost rising is very limited, bearing but is greatly improved service life.The utility model is reasonable in design, function admirable, and processing and manufacturing is simple, and is convenient and practical.
