Abstract
The utility model discloses a compound bearing for finely grinding an inner ring and an outer ring, which comprises a main shaft (2), a grinding wheel (1) arranged on the main shaft (2), a locking nut (3) for fixing the grinding wheel (1) and an inner/outer ring (4). The grinding wheel (1) can grind the raceway of the inner/outer ring (4). A compound bearing (5) is arranged at the lower end of the inner/outer ring (4), and the center of the compound bearing (5) is overlapped with the center of gyration of the inner/outer ring (4). The compound bearing provided by the utility model has a simple structure, can grind the inner ring and the outer ring at the same time, and solves the problem that when the inner ring and the outer ring are finely ground, tool set cushion blocks are required to be replaced. When the compound bearing is used to grind the inner ring and the outer ring, the used tool set cushion blocks are the same type and do not need to be changed, which is time-saving and labor-saving, so as to improve the machining efficiency, save the machining cost and enhance the competitiveness of products in the market.
Description
Technical field
The utility model relates to a kind of supporting, what be specifically related to is a kind of composite support that finish grindes inside and outside lasso.
Background technology
1.5MW about and the pitch variable bearings that adopts of above wind-driven generator comprise inside race, outer collar and steel ball.Two raceway quality of the inside and outside lasso of pitch variable bearings have crucial effects to whole pitch variable bearings, thus to carry out grinding to raceway, and the requirement of ovality and tapering is arranged.During the inside and outside lasso grinding of pitch variable bearings, with frock cushion block difference, processing when inside and outside lasso exchanges needs the expensive time to change frock, and this has just caused whole operation to process the waste in used man-hour, has caused waste for the cost of the manufacturing assembling of pitch variable bearings.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of composite support that reduces the inside and outside lasso of correct grinding of changing the frock time, has the minimizing manufacturing cost, reaches the purpose that abridged edition is spent more money on.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises main shaft, is arranged on the emery wheel on the main shaft, the locking nut that is used for fixing emery wheel and inside and outside lasso, described emery wheel can be internally, the raceway of outer collar carries out grinding, also comprise the composite support that is arranged on inside and outside lasso lower end, the center of composite support and the centre of gyration of inside and outside lasso coincide.Adopt composite support to finish the grinding of the inside and outside lasso raceway of pitch variable bearings, reduce the time of changing frock, reduce manufacturing cost, reach the purpose that abridged edition is spent more money on.
Described composite support length is 160mm, and width is 80mm, highly is 50mm.
The utility model is simple in structure, can process inside and outside lasso simultaneously, when having solved the inside and outside lasso of correct grinding, needs to change the problem of frock cushion block.When adopting the utility model to process inside and outside lasso conversion, do not need to change the frock cushion block, used frock cushion block is same, time saving and energy saving, thereby has promoted working (machining) efficiency, has saved processing cost, has promoted the competitiveness of product in market again.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, the utility model comprises main shaft 2, is arranged on the emery wheel 1 on the main shaft 2, the locking nut 3 that is used for fixing emery wheel 1 and inside and outside lasso 4, emery wheel 1 can be internally, the raceway of outer collar 4 carries out grinding, also comprise the composite support 5 that is arranged on inside and outside lasso 4 lower ends, the centre of gyration of the center of composite support 5 and inside and outside lasso 4 coincides.
When adopting the composite support 5 of the inside and outside lasso 4 of correct grinding, the center of finding out composite support 5 is put in the centre of gyration place of inside and outside lasso 4, composite support 5 is fixed on the grinding machine platform, do not moved bearing position when so not needing to grind inside and outside lasso 4, no matter grind inner ring or outer ring, workpiece can both lie against on the composite support 5.
Because composite support 5 length are longer, might collide composite support 5 by locking nut 3 when grinding like this, can reduce locking nut 3 highly accordingly, in order to avoid collision.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
- One kind the correct grinding inside and outside lasso composite support, comprise main shaft (2), be arranged on the emery wheel (1) on the main shaft (2), the locking nut (3) that is used for fixing emery wheel (1) and inside and outside lasso (4), described emery wheel (1) can be internally, outer collar (4) raceway carries out grinding, it is characterized in that, also comprise the composite support (5) that is arranged on inside and outside lasso (4) lower end, the centre of gyration of the center of described composite support (5) and inside and outside lasso (4) coincides.
- 2. the composite support of the inside and outside lasso of correct grinding according to claim 1 is characterized in that, described composite support (5) length is 160mm, and width is 80mm, highly is 50mm.
