Description
Technical field
The present invention relates to a kind of fork truck small size camshafts to hold, and is applied to fork truck mechanical field, specially a kind of fork truck cam
Bearing.
Background technique
It is mainly made of outer ring, mandrel, rolling element, sealing ring, retaining ring etc. for fork truck mechanical bearing.Using in outer ring and
Rolling element is installed, rolling element uses roller, is evenly distributed between outer ring and inner ring, sealing ring plays dust-proof and anti-between inner ring
Water effect.Bearing capacity is higher in the operating condition as used in production fork truck cam, and pivoting friction is larger, and Bearing inner is easy mill
Damage, leads to premature failure, so just devising this new model bearing.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, and according to a kind of fork truck applying working condition demand, invention design is outer
Circle is internal to be provided with an oil storage tank, improves greasy property convenient for storage grease and forms oil film, mitigates internal friction；According to this hair
The technical solution of bright offer, micro precision bearing include outer ring, mandrel, rolling element, sealing ring, retaining ring, lubricating grease etc..
Primary solutions way of realization of the invention is as follows：
A kind of fork truck camshaft bearing is provided, which is characterized in that including：
Outer ring, mandrel, rolling element, sealing ring, retaining ring and oil storage tank；
The mandrel is located in outer ring, is circumferentially provided with multiple rolling elements uniformly at intervals between mandrel and outer ring,
It by setting retaining ring on the outside of the outer ring, is sealed between retaining ring and outer ring by sealing ring, the oil storage tank is provided in outer ring
On wall center,
Lubricating grease is filled in the oil storage tank.
Improvement to above-mentioned technical proposal, the oil storage tank is having a size of 0.8 × 0.6mm.
Improvement to above-mentioned technical proposal, outer ring outer diameter are 22.2 ± 0.1mm, and width is 12.7 ± 0.1mm, and internal diameter is
13.49±0.1mm。
Improvement to above-mentioned technical proposal, mandrel channel outdoor scene are 10.49 ± 0.1mm, and width is 36 ± 0.1mm, non-ditch
Outer diameter is 9.52 ± 0.1mm at road；
Improvement to above-mentioned technical proposal, the size of rolling element 4 are 1.5 × 9.8mm of φ, and quantity is that 25 intervals are uniformly distributed knot
Structure；
68 outer diameter of sealing ring is 17.55 ± 0.1mm, and internal diameter is 15.25 ± 0.1mm；
12 outer diameter of retaining ring is 15.4 ± 0.1mm, and internal diameter is 9.75 ± 0.1mm.
The advantage of the invention is that：
By needing to reinforce bearing internal lubrication effect to analyzing in the past using bearing effect, an outer ring is thus devised
Inside is provided with the bearing of a groove, has the function of storing lubricating grease.The main function of this patent is exactly to enhance greasy property,
The phenomenon that reducing Bearing inner abrasion premature failure.
Detailed description of the invention
Fig. 1 is bearing arrangement schematic diagram of the present invention.
Specific embodiment
Below with reference to specific drawings and examples, the invention will be further described.
As shown in Figure 1, the present invention provides a kind of fork truck camshaft bearing, which is characterized in that including：
