But gear drive can exist transmission sideshake, sideshake can prevent from the one hand due to error and thermal deformation, gear being blocked, and gives lubricating oil film retaining space, but makes on the other hand mechanism accurately not locate.Therefore, in the occasion that needs high accuracy transmission, must adopt suitable Error Adjustment Method, with departure amount, reach better operational effect.At present, what the assembling of toothed planet-gear speed reducer adopted mostly is manual debugging mode, relies on assembler's experience, cannot ensure installation accuracy, is therefore badly in need of a set of assembly tooling of design and solves this practical problem.

Utility model content

The purpose of this utility model is for the deficiency in above-mentioned background technology, a kind of simple in structure, easy to operate, planetary speed reducer with small tooth number difference assembly tooling that operating efficiency is high is provided, by adjusting gear centre apart from eliminating backlash, can effectively ensure assembly precision.

The technical scheme that the utility model provides is: a kind of assembly tooling of planetary speed reducer with small tooth number difference, is characterized in that this frock comprises the planet carrier clamp axis that is fixed on the ring gear support frid of locating for decelerator ring gear on pedestal, the planet carrier eyelid retractor of locating for decelerator planet carrier and locates for reducer input shaft.

Described planet carrier eyelid retractor comprises vertical lifting gripper shoe to decelerator planet carrier outer circumference surface location use, for the vertical Sliding Structures of vertical lifting gripper shoe vertical direction position adjustments and for the horizontal sliding structure of vertical lifting gripper shoe horizontal direction position adjustments.

Described horizontal sliding structure comprises the frid that is fixed on base-plates surface and is shaped with horizontal concrete chute and the slide block being slidably matched with horizontal concrete chute.

Described vertical Sliding Structures comprises the position, both sides of the edge of vertical lifting gripper shoe, is slidably matched and bottom is fixed on the guide plate on described slide block and is positioned at vertical lifting gripper shoe below and vertical lifting gripper shoe is applied from lower and toward the spring of uplifting pressure by two vertical lifting chutes and position, aforementioned both sides of the edge.

End face and the matched inner concave of outer circumference surface with decelerator planet carrier made in one end of described planet carrier clamp axis, the other end by a capacity eccentric bearing rotationally horizontal location on a baffle plate.

Make and the matched inner arc surface of decelerator ring gear outer circumference surface on the top of described vertical lifting gripper shoe.

Described ring gear supports the top of frid and makes and the matched groove of decelerator ring gear outer circumference surface.

The beneficial effects of the utility model are: hold the centre-to-centre spacing that can change planetary gear and ring gear by eccentric rotation axis, thereby reach the object of eliminating gear backlash, without external power supply.This assembly tooling is simple in structure, easy to operate, can significantly improve the efficiency of assembling of planetary speed reducer with small tooth number difference, laborsaving when joint, can ensure certain assembly precision simultaneously, and the gap that disappears is effective.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.

A kind of planetary speed reducer with small tooth number difference assembly tooling as shown in Figure 1, comprises from left to right successively for the ring gear support frid 11 of decelerator ring gear location, the planet carrier eyelid retractor of locating for decelerator planet carrier and the planet carrier clamp axis 4 for reducer input shaft location.

On described pedestal 1, be welded with successively ring gear and support frid 11, the frid 12 that is shaped with horizontal concrete chute and baffle plate 13.Wherein, ring gear supports the top of frid 11 and makes and the matched groove of decelerator ring gear outer circumference surface, can be used for fixing planetary reduction gear ring gear 8; Its both sides circular arc trough rim is also provided with screw, by holding screw 11-1, planetary reduction gear ring gear is fixed, and prevents that ring gear 8 from adjustment gear backlash process, radial and axial motion occurring.Slide block 14 can move as transverse horizontal in horizontal concrete chute, thereby makes vertical lifting gripper shoe 3 upper end arc-shaped edges and planet carrier 9 concentric all the time.On baffle plate 13, certain altitude place has a hole, for setting-up eccentricity bearing 5(sliding bearing).

On described slide block, symmetry has been installed two guide plates 2 and two spring mounting holes, and spring 6 is all the time in compressive state, thereby vertical lifting gripper shoe 3 upper end arc-shaped edges and planet carrier 9 outer circumference surfaces are close to.Each vertical lifting chute of making on two guide plates, the dual-side of vertical lifting chute and vertical lifting gripper shoe 3 is slidably matched along position, adds upper spring and forms vertical Sliding Structures; Vertical lifting gripper shoe can move up and down along vertical lifting chute, by the position of the holding screw lockable vertical lifting gripper shoe 3 on guide plate.

Described vertical lifting gripper shoe 3 is for lifting planet carrier 9, follows planet carrier 9 and moves adjusting in gear backlash process, and its upper end arc surface equates with planet carrier 9 outer circumference surface radiuses, and lower end is provided with two spring mounting holes.

End face and the matched inner concave 4-1 of outer circumference surface with decelerator planet carrier made in described planet carrier clamp axis 4 one end (showing left end in Fig. 1); When work, decelerator planet carrier can embed in this concave surface, then can make planet carrier and planet carrier clamp axis be fixed together by holding screw.The other end of planet carrier clamp axis is rotatably positioned on baffle plate 13 by the capacity eccentric bearing 5 of socket (key connection).For two baffle plates guaranteeing that planet carrier clamp axis axis is horizontal, can adopt to be arranged in parallel support the two ends (as shown in Figure 5) of planet carrier clamp axis; Capacity eccentric bearing wherein, can adopt the capacity eccentric bearing of a lengthening to intert respectively on two baffle plates.
