Abstract

The utility model relates to a speed reducer used for the meat chopper, which comprises a box body and a box cover which is arranged by being matching with the box body. The speed reducer is characterized in that an axial bearing is respectively arranged in the box body and the box cover, an input gear shaft is arranged on the axial bearing, a gear on the input gear shaft is meshed with an output gear, the output gear is fixedly arranged on an output shaft, the output shaft is fixedly arranged on the box body and the box cover, and a sealing device is arranged on the lateral surface of the axial bearing; the sealing device comprises asbestos, a nylon clamp ring, an oil slinger and a double-layer reinforced seal; the box cover is provided with a rabbet on an output end surface, and a bolt hole is also arranged on the rabbet. Therefore, the speed reducer has the advantages of small volume, high bearing capacity, reliable running, low noise, good sealing effect, etc.

Description

The meat grinder speed reducer

Technical field

The utility model belongs to food processing machinery, particularly relates to a kind of meat grinder speed reducer.

Background technique

In present meat product working machine, requirement to speed reducer is more and more higher, especially in the Minced Steak industry, existing meat grinder generally can not be directly with speed reducer and the reamer of meat grinder directly dock, but connect, so cause the volume of speed reducer and noise bigger by joiner or coupling; Because the meat grinder working particularity adopts above-mentioned connecting mode, card machine or stifled machine phenomenon occur through regular meeting, thereby speed reducer casing and gear are caused damage; Existing in addition speed reducer generally adopts seal ring to realize sealing, because working particularity, seal ring will wear out and wear and tear gradually, and simple seal ring is to reach sealing effect, so the speed reducer oil leakage phenomenon is more serious.

Summary of the invention

A kind of volume is little, bearing capacity is high, the meat grinder speed reducer of good sealing effect for the technical problem that exists in the solution known technology provides for the utility model.

The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of meat grinder speed reducer, comprise casing, cooperate the case lid of installing with casing, it is characterized in that: in casing and case lid, be separately installed with spring bearing, the input gear shaft is installed in the spring bearing, gear engagement output gear on the input gear shaft, output gear is packed on the output shaft, and output shaft is packed on casing and the case lid by spring bearing, is provided with seal arrangement in the side of spring bearing; Described seal arrangement comprises: asbestos, nylon hold-down ring, disc and double-deck outside framework oil seal; Described case lid is provided with seam at output end face, also has screw on seam.

The utility model can also adopt following technical measures:

The gear of described input gear shaft is a helical gear.

The big end of described output shaft is installed in the outer end of case lid.

One end of described output shaft is provided with thrust-bearing.

Advantage and the good effect that the utlity model has are: because the utility model helical gear adopts the hard flank of tooth, the ways of deceleration of roll flute, efficiently solve existing speed reducer overload capacity problem, guaranteed the reliability of gear engagement, reduced the noise of unit running; Output terminal at output shaft directly directly docks with meat grinder by seam and bolt, saved connection space like this, reduced the volume of whole speed reducer, for effectively solving card machine and the stifled machine phenomenon that the strand chilled meat causes, thrust-bearing has been installed at the other end of output shaft; Also adopt unique sealing means in addition, i.e. its big end of output shaft outside of stretching out case lid, and, solved oil leakage phenomenon effectively by multiple backflow sealing means such as asbestos, nylon hold-down ring, disc and double-deck outside framework oil seals; In addition the utility model also have simple in structure, volume is little, speed ratio is little, advantage such as reasonable in design.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an I portion enlarged view among Fig. 1.

Among the figure: 1, case lid; 2, bearing; 3, input gear shaft; 3-1, gear; 4, bearing; 5, casing; 6, thrust-bearing; 7, bearing; 8, flat key; 9, output gear; 10, bearing; 11, seal arrangement; 12, output shaft; 13, seam; 14, screw; 15, asbestos; 16, nylon hold-down ring; 17, disc; 18, double-deck outside framework oil seal.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, drive bearing 4 that is packed in the casing 5 and the input gear shaft 3 that installs 2 together support of bearing in the case lid 1 through the motor (not shown), gear 3-1 on the input gear shaft 3 is a helical gear, the helical gear 3-1 engagement output gear 9 of input gear shaft, output gear 9 is packed on the output shaft 12 by flat key 8, spring bearing 7 also is housed on the

output shaft

12,10 support output shaft 12 rotates, output shaft 12 is packed on the casing by spring bearing 7 and spring bearing 10, gear 3-1 and output gear 9 all adopt the hard flank of tooth, the ways of deceleration of roll flute, efficiently solve existing speed reducer overload capacity problem, guarantee the reliability of gear engagement, reduced the noise of unit running.For solving oil seepage phenomena effectively, be provided with unique seal device 11 in the side of spring bearing 10, it is the outside that its big end of output shaft stretches out case lid, the sealing device also comprises: asbestos 15, nylon hold-down ring 16, disc 17 and double-deck outside framework oil seal 18 guarantee sealing effect by multiple backflow sealing means such as asbestos 15, nylon hold-down ring 16, disc 17 and double-deck outside framework oil seals 18.For solving phenomenons such as card machine that the strand chilled meat causes and stifled machine, a thrust-bearing 6 also is housed at the other end of output shaft 12.Case lid 1 also is provided with seam 13 at output end face, also have screw 14 on seam, case lid 1 passes through bolton with casing 5, and case lid 1 directly is connected with bolt by seam 13 with the meat grinder (not shown), save connection space like this, reduced the volume of whole speed reducer.
